Ask HN: Who is hiring? (December 2025)

BuildBetter | Senior Engineer (Backend, Full-stack) | Full-Time | Remote (US) | 170-200k base + equity | Visa Sponsorship not provided

BuildBetter is the product operations platform for customer-led teams. We've built an AI-first product that lets our customers, like Rappi, n8n, Posthog, and Brex automate the operations work that lets them provide their customers with world-class product experiences.

We're looking for two senior engineers to join the team; our headcount has remained small while growing revenue, and we're now bottlenecked by development speed in a way that will make you invaluable. You'll have real ownership over your code from product ideation to customer support, and we'll be making substantive product updates weekly. We're looking for team players who are as fun to work with as they are productive, and are willing to compensate these two rolls commensurately - our aim is to be in the 95th percentile of equity compensation, and we expect that in exchange we'll have value-aligned employees who will help us grow the business.

Joining us will mean solving hard problems at the frontier of AI adoption, including:

- maintaining performance at scale

- building and maintaining rich frontend user experiences that maintain the standards of usability and delight that our customers know us for.

- building agent and workflow systems that automate real work for customers

- playing around with the latest models to figure out new experiences that we can offer our customers as cutting-edge models get released monthly

- building automation that's grounded in supporting product teams rather than automating them - our bet is that this is the likelier outcome out of the current generation of AI systems

Stack: Postgres / TS (Nest + React) / Hasura / EKS / S3 / LLM APIs / Python

Benefits:

- unlimited PTO

- $100/mo education stipend

- flexible hours: we measure productivity in terms of outcomes, not time, so as long as you're able to stay aligned, productive, and in regular communication, we don't really care what hours you work

- health insurance

Please reach out to: nikhil (at) buildbetter (dot) app

Zed Industries | North America, South America, Europe REMOTE | https://zed.dev/

Zed is a company for developers, by developers. All 3 of our founders have spent years in the trenches writing software and still do it almost every single day. We know the only way to build the world's best code editor is by equipping every single member of the team to do the best work of their career.

We've raised $42M (https://zed.dev/blog/sequoia-backs-zed) to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.

Mulligan Post, Inc - On-Site near Millbrae BART/CalTrain Station in Burlingame - $60-120/hour Contract - Mechanical Design Engineer / Mechatronics / Industrial Automation.

Software hacker seeking hardware hacker to make custom robots for Magic: The Gathering automated storage and retrieval system to power an online e-commerce store (think CardKingdom competitor or eventual TCGPlayer competitor.) In terms of scale, the eventual target is >100k different _skus_, million items in inventory, tens of thousands picks per day. The industry is large; eBay bought TCGPlayer for $300M about 3 years ago.

I am looking for a mechanical/electrical/hardware generalist to complement my software expertise. Someone who knows how to integrate off the shelf parts into custom automation to solve problems. If fast iterations, direct connection with the project in use, autonomy and minimal bullshit overhead appeals to you then this could be a great fit. You are: someone who makes stuff and solves problems, is a clear communicator and fast study. You know how to challenge a requirement, source an off-the-shelf-part or design custom manufacturable part and when to do each. I don't really care where or when or what your degree is in if you have demonstrated driving things to completion and we vibe well enough.

We will use OnShape (license/seat will be provided) for collaboration and document management reasons. Much of what we need to build is integrating FUYU linear rails, Clearpath motors, pneumatics with some custom Send Cut Send / Xometry parts, 8020 frames, etc.

Pros: Small team / minimal overhead and wide scope. Clear guidance on what to build. Flexible-ish schedule (core hours 9-5 in office, flexibility for school breaks, etc.) Real problem with established market.

While I'm primarily looking for a contractor for now, I am open to the possibility of bringing the right person on full-time with equity if they are interested and invested in the space, but that is not a requirement and it probably makes sense to establish that after working together for a bit.

No recruiters or third parties, not able to sponsor at this time. Compensation dependent on experience.

Hiring process: resume/project review, vc chat < 1 hour, then paid 1-day work trial where we see if we fit.

If you're interested, send me an email - [email protected]

SpruceID (YC W21) | REMOTE (US-Based Preferred) | Full-Time | spruceid.com

Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.

The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.

We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.

We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.

Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.

We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

Join as the 4th team member to redefine the most universal interface in business: the spreadsheet. We are building an AI spreadsheet that automates knowledge work, allowing users to describe tasks in plain English and get immediate, trustworthy results. We launched a few months ago, already have paying customers, and are backed by top investors like Base10 (Brex, Figma). This is a massive opportunity to take the interface for this market shift.

Compensation & Equity: $150,000 - $200,000 + meaningful early-stage ownership

We're building the tool that saves users hours of manual work (data cleaning, formula building) currently required by legacy spreadsheets. Our team includes engineers who shipped production AI and distributed systems at Microsoft and VMware. We intend to replace Excel and Google Sheets by building the spreadsheet that truly understands what users want.

Why We’re Hiring a Founding Engineer You will own the core product end-to-end, building AI agents that reason over data and evolving our spreadsheet engine for correctness and scale. You'll ship critical UX that allows non-technical teams to get analysis in plain English. We need a generalist who moves fast across the full stack: Node.js, TypeScript, Express, and Rust + WASM. High agency, high ownership, and a focus on user trust are essential.

Aloe | Vancouver, BC, Canada (ONSITE preference)

Aloe is the critical thinking layer for agents – to know why they believe what they do, how confident they are, and what actions they can take to increase that confidence. It’s the only path to AI we can trust, delegate to, and rely on.

Aloe exists to build tools to help human cognition succeed in an information-dense world it did not evolve to handle. We believe this is the most important problem to solve today.

MixRank (YC S11) | Software Engineers | 100% REMOTE (Global) | Full-Time MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security.

We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.

We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.

Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.

We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.

We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.

-- Junior Software Engineer - Remote (Global), Full-Time

We're looking for remote junior engineers that have 0-3 years of professional experience in software, and 5+ years of curiosity exploring computers, programming, and technical hobby projects. This is an open-ended entry role with mentorship and diverse opportunities to work on all areas of our product: databases, distributed systems, infrastructure and tooling, data analysis, machine learning, frontend/backend web development, APIs, data mining, data modeling, and more. To stand out, please highlight what makes you unique: passion for computing, curiosity and side projects, work ethic, niche research, etc.

Ideally you've already graduated, but if you still have one or more years left of school, please feel free to apply anyway, and if you're the right fit for the team we'll figure out a way to accommodate your schedule.

Saildrone | Multiple Roles | Onsite/Hybrid (US Only) | SF Bay Area (Alameda) | Full-Time | https://www.saildrone.com/

Saildrone is the world's leading collector of ocean-related in situ data via uncrewed vehicle, above and below the sea surface. We work with navies across the world to deliver insights about waterways, contribute to safety of life at sea, and mitigate illegal fishing and trafficking. Additionally, we work with governments, civic agencies, foundations, universities, and private companies around the globe to derive better information about our oceans and seas - be it sailing drones into the eye of hurricanes to obtain new scientific storm data, mapping out the ocean floor, collecting new CO2 data in hard-to-reach areas, or counting biomass to establish fishing quotas.

Maybe you saw that we've repeatedly hucked drones into category 4 hurricanes[1]. Or maybe that we completed a transoceanic cable survey for Meta[2]. And maybe you saw that we just announced a large partnership with Lockheed Martin[3]. Or maybe you didn't see any of that, but you're still intrigued by the idea of autonomous, long endurance sailboats that help us better understand and secure our planet.

Whatever the case, we're hiring for a breadth of different positions across our organization. In software, we're hiring for folks in our Perception, Platform, Frontend, and Vehicle teams. Stacks vary from team to team, but we're looking primarily for folks with backgrounds in C++, Python, and/or JavaScript (Node, TypeScript, React). All software positions are hybrid roles based out of Alameda, just a quick ferry ride across the Bay from San Francisco.

In addition to software engineers, we're also hiring for a bunch of other positions across the company in production/manufacturing, technical operations, and more.

You can see a list of open positions on our career page: https://www.saildrone.com/careers

Goblins | https://goblinsapp.com | Founding Engineer #3 | Williamsburg, New York | ONSITE | $100-200k (+ generous equity)

At Goblins, we're building America's favorite teacher, starting with K-12 math. We're live in thousands of classrooms for in-class assignments, extra practice, and homework. Students work on a whiteboard while our models analyze their work in real time and nudge them with questions that make them think. Teachers get instant visibility into how the class is doing, who needs help, and what to assign next.

We just raised our seed round and are backed by the Gates Foundation, giving us the ability to build something transformative in education.

Here's what you might work on:

- Create shareable "aha moment" videos from real student sessions.

Turn anonymized whiteboard work and Goblin–student dialogues into short videos or interactive replays that highlight the value of Goblins. Automatically identify the best moments, strip out sensitive data, and produce artifacts that teachers, parents, and districts want to watch and share.

- Rewrite our diffusion transformer real-time avatar stack.

Our Goblin avatars are already in production. Improve audio–motion sync, temporal coherence, and expressiveness, while cutting latency and cost so they run smoothly at 100k+ student scale.

- Extend continuous diagnostics to high-stakes like the SAT and ACT.

We track mastery against state standards with our spin on IRT. Extend this to SAT/ACT-style exams: infer score distributions from behavior, validate on real data, and compute minimal targeted practice that reliably moves predicted scores.

- Design uncheatable problem formats.

Generative AI can solve most traditional math problems and show fake work. Build formats where copying is harder than thinking: dynamic graphs, constructive proofs, counterexample generation, debugging flawed solutions, multi-step conceptual checks. Make them auto-gradable, resistant to copy-paste, and stable at scale.

- Build real-time instructional agents.

Detect underlying student misconceptions from their work and have an agent "drop in" only when needed. It should generate short, visual, 3blue1brown-style explanations tailored to the specific misunderstanding, and create diagrams, animations, and interactive examples that adapt as the student responds.

The role is based in our Williamsburg, Brooklyn office in NYC (on-site only). You'll join our tight-knit founding engineering team of 3—myself (the CTO) and two founding engineers with collective experience from Stanford, Stripe, Amazon, and X1.

As our third founding engineer, you'll have full ownership of critical projects and ship production systems that impact thousands of students and teachers in real classrooms within your first few weeks.

If this sounds fun, and you want to help inspire 1 billion kids to love to learn, email [email protected] :)

Duranta | Full-Time | Staff backend engineers | Location: Seattle, WA or NYC | On-site

Company: we're a small startup (pre Series A) building a business-in-a-box solution for landscaping companies, initially targeting the US. It's a huge market with more than 700000 companies in the US alone but with very little good software. We're looking for a very experienced backend engineer (senior/staff level) capable of taking ownership and leading the development of entire systems.

We keep our infrastructure as simple as possible, so the entire backend is in Golang with Postgres+S3 as the data storage layer. And a bit of Terraform for the infrastructure.

We're NOT a standard "AI startup" doing LLM wrappers, but we do have our own computer vision AI that we use to produce models from satellite imagery. So if you're interested in working on unusual AI pipelines, we have plenty of work there too.

Our frontend is a React.Native app, and we're working towards having full feature-parity inside a regular webapp.

Experience:

* Go backend experience

* A lot of experience with distributed systems

* Designing robust APIs (we're using ConnectRPC)

* Ideally experience with offline apps and database synchronization

* The usual: infrastructure-as-code, Docker, Github actions, OpenTelemetry, etc.

Salary: $170-$210k and equity

I’m not sure if this is the right place to post this, but to everyone commenting here saying they’re hiring and asking people to send their CVs —

please have the basic decency to send a simple acknowledgement or revert after receiving them.

This has happened repeatedly over the past few months after sending dozens of emails from these threads, sometimes 10+ at a time. Not getting even a basic response feels extremely disheartening.

I know it’s a tough time for everyone searching for a job, and we all understand if things are slow —

but a small confirmation like “Received, we’ll check” or “Not hiring anymore” takes 5 seconds and makes a world of difference.

Let’s be kinder to each other. It’s been a very hard year
