Ask HN: Who is hiring? (April 2025)

Elicit | San Francisco + remote (US timezones) | https://elicit.com/careers

Elicit is an AI research assistant that uses language models to help researchers figure out what’s true and make better decisions. We scaled to >$5MM annual revenue and 450k MAU fast. We're hiring for multiple roles and are primarily interested in people with early-stage company experience, who are comfortable in high-agency, fast-paced teams.

Reasons you might want to join Elicit:

1. We have been thinking about how to apply AI for high-stakes knowledge work since even before GPT-1. Elicit was spun-out from Ought (https://ought.org/) which was an applied research lab.

2. If you're concerned about the potential downsides and risks of super-powerful AI: so are we! Happy to explain more of this story on a call, or you can also check e.g. https://ought.org/updates/2022-04-06-process for a primer.

3. We like spending time with each other, and have get-togethers every 6 weeks, but we're flexible on location.

Reasons you might not want to join Elicit:

1. We've found a level of product market fit (as evidenced by metrics) but we've not proven everything out yet. If you want predictability, Elicit is not for you.

2. We aim to hire people who thrive in low-bureaucracy environments, and let them loose. If you need structure, lots of support, close mentorship, or tightly-defined work assignments, Elicit is not for you.

Tired of trying to beat kube into shape? Does writing YAML to ship code fill you with utter dread? Dream of a future where deploying software is simple, and you don't need an army of infrastructure engineers to build that perfect janky bash script™ to make life easy?

We're Railway, and we think infrastructure can be better. So far we've built out a platform loved by hundreds of thousands of users who simply tell us "Give me Postgres", "Deploy this repo", and we make it happen

Fair warning! The problems are complex: home-rolled hypervisors, cut-above container orchestration, over/under/whateverlay networks, virtio device drivers, edge proxies, IAM that doesn't suck, kitchen sinks - we need to build it and we're looking for likeminded individuals who think this stuff is fun.

Four open roles (apply below!):

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.

Fulcrum | Senior and Staff Full Stack Engineer | MSP | $160k - 200k+ + benefits and equity | Full-time, REMOTE (US) or HYBRID (Minneapolis) | https://fulcrumpro.com Our mission is clear and staggeringly important: we're building the manufacturing operating system of the future from the ground up, one that’s engineered to create network effects as we grow. A beautiful, sophisticated quantum leap forward for the most important core industry in the world. The market tells us we’re on the right track and we're growing. Currently seventeen developers. (Many from HN!). Series A-2: https://fulcrumpro.com/ignite

We’re serious about doing great work and we empower people to make it happen. Our favorite tools include C#, Angular, Vue, and serverless TypeScript. We’re primarily interested in finding intensely smart people with talent at their fingertips, regardless of what tech stack you come from. We value autonomy over routine, and empathy over ego.

Manifesto: Manufacturing is important. It’s the fundamental industry on which everything else is built. We take it for granted. In 1989, 35% of the entire software industry was manufacturing systems. Back then, services, hand holding, customization, and consulting were necessary to get the systems to where they are today. What was the first massive burst in productivity from technology has stagnated into incremental diminishing returns and exponentially increasing complexity. We can only continue to add complexity for so much longer until the whole system collapses. "Any intelligent fool can make things bigger and more complex. It takes a touch of genius and a lot of courage to move in the opposite direction." Manufacturing is important. We must deliver a touch of technological genius to reintroduce simplicity, efficiency, and integration.

Roboflow | Solutions Architects, Implementation Engineer, Recruiter, Full Stack Engineers | Full-time (Remote, SF, NYC) | https://roboflow.com/careers?ref=whoishiring0425

Roboflow is the fastest way to use computer vision in production. We help developers give their software the sense of sight. Our end-to-end platform [1] provides tooling for image collection, annotation, dataset exploration and curation, training, and deployment.

Over 1 million engineers (including engineers from 2/3 Fortune 100 companies) build with Roboflow. We now host the largest collection of open source computer vision datasets and pre-trained models [2]. We are pushing forward the CV ecosystem with open source projects like Autodistill [3] and Supervision [4]. And we've built one of the most comprehensive resources for software engineers to learn to use computer vision with our popular blog [5] and YouTube channel [6].

We have several openings available but are primarily looking for strong technical generalists who want to help us democratize computer vision and like to wear many hats and have an outsized impact. Our engineering culture is built on a foundation of autonomy & we don't consider an engineer fully ramped until they can "choose their own loss function". At Roboflow, engineers aren't just responsible for building things but also for helping us figure out what we should build next. We're builders & problem solvers; not just coders. (For this reason we also especially love hiring past and future founders.)

We're currently hiring for full-stack engineers to help build our product, field engineers that work directly with our customers to solve their business needs with computer vision, and several technical roles on the sales team.

We just raised our Series B round, led by GV. With this round, we will continue building the open source tools, platform, and community so developers and enterprises can deploy computer vision applications to production. [7]

Chorus One | https://chorus.one/careers | Platforms Engineer | REMOTE (Switzerland ± 6 hours)

Chorus One operates validators on many proof-of-stake blockchains (the ones where security is based on a Byzantine fault-tolerant consensus algorithm rather than wasting energy). We are hiring for several roles, but the one I will highlight is what we call Platforms Engineer. Some companies call this Site Reliability Engineering or Devops.

The main thing we do is take upstream software, build it, run it on our infrastructure, and then monitor it and optimize that setup. Some things that make this interesting are:

    * Building automation that enables us to do this for many networks (70+ currently).
    * Doing this with high uptime, building automation for failover, etc.
    * Working with software that is on the one hand cutting-edge and doing interesting things (consensus algorithms, distributed systems, cryptography), but on the other hand that means it’s immature and often not easy to operate and monitor. Often we have to build custom tools, and dive into the source code of the project. We contribute patches upstream when it makes sense.
    * Some of these projects are exercising the limits of what a machine can do, we have to do some low-level investigation that requires understanding of what the Linux kernel and network hardware are doing to properly identify what’s going on.

A recent example of what I personally find fascinating: last month Ethereum’s Holesky testnet experienced loss of liveness. This is a real-world, globally distributed system that implements Byzantine fault tolerance, with multiple independent implementations of the protocol. Several of these implementations had a bug in an update, which caused a split in the network. The protocol is designed to handle this situation in theory, but in practice it is triggering previously unexplored failure modes in the implementations, that are hard to test for in synthetic small-scale tests. I think there are very few places where you get to be involved in a planet-scale distributed system exhibiting “interesting” behavior, especially one that is not in control of a single entity. Of course, there is also the less fun part that the testnet was broken, alerts are firing, and it was hard and chaotic to coordinate a fix when the network is not controlled by a single entity. Fortunately it’s a testnet.

Not actually hiring in the US. Check Connor's previous postings. Now they're not even pretending that they can afford US hires.

They take forever to reply (2 months since my first email, meanwhile they regularly kept posting the job on HN) and after the initial call had me take a home assignment that I spent almost an entire day on, then went total radio silence again - not even a generic "sorry for the delay" or a rejection email. I see I'm not an outlier, given others' comments under their postings. I don't think the job's fake - they just really don't care about their candidates' time.

Don't bother applying to this one, as it's a ghost job posting (you can check for yourself in previous Who is Hiring posts dating all the way back to 2023)
