Coop (https://smart.coop.farm)| 2nd Founding Engineer | iOS Heavy Engineer | Hybrid onsite | Austin, TX | Full-time, Part-time

My name is AJ Forsythe and I'm the Founder / Chief Chicken Tender at Coop! We're an Austin TX based company on a mission to build the world’s largest decentralized food production network, starting with AI powered chicken Coops. We’ve been in the market for about 18 months and our customers are in 48 states and will generate about >10M eggs this year. It's insanely fun to work on and we have a shot at building a huge business in the connected urban farming space. If you’re big into computer vision, consumer products that are fun, and an awesome team we would love to chat. The Coop has an automatic door + cameras doing computer vision work (predator detection, egg alerts, remote health monitoring, etc). It's a super exciting time and are seeing directional product market fit which I'm thrilled about. Seriously go check out our website, it's a super fun + amazing product.

We’re a tight-knit team of 5 people with 15+ years of experience working together. We’ve been through YC, started and scaled multinational million-dollar businesses together, taking them from idea to acquisition by a Fortune 50 company. We’re gritty and passionate without taking ourselves too seriously - and we’re here to build something really exciting that helps people reconnect with their food and the planet. We're VC backed (call it $5M) by some of the world's best investors but we are a scrappy small team that moves fast.

We have an absolutely fantastic CTO Ryan that I'm looking for his / our right hand person to work alongside with. I think the term full stack is overused but that's closest to what we're looking for. Also this really isn’t a traditional Eng role, I look at it as we’re a small growing team and you would be one of us working on a ton a cool projects on day 1. Also, we LOVE working with founders so if you've started a company before that's epic.

Oh also, I have a fun project where I want to make a water gun turret that uses our cameras to detect predators and allows you to aim and blast them. If you're into hacking robotics and gimbals etc, please reach out.

You can also reach out to me directly at: aj[at]coop.farm - Just email me your LinkedIn / GitHub / portfolio + why you think you'll be an awesome fit and I'll respond. Please don’t use GPT too much. This is my 3rd company (2 have exited) and I want to build the super solid core team and you might be the perfect fit for us and vice versa.

Loophole Labs | Senior Systems Engineer | REMOTE (Americas & Europe) | $150k–195k USD + equity | Go, Zig, Rust, C, eBPF, CRIU, Kubernetes

We make Architect: a Kubernetes runtime that hibernates idle pods in place and wakes them in 50ms with TCP connections intact. Five engineers. You'd be the 6th.

If tracing an x86 instruction in the morning and hunting a control-plane race in the afternoon both sound fun, and you insist on measuring rather than guessing, this is the job.

Customers run Architect for workloads where cold starts hurt: real-time voice & video AI agents, long-warming JVM apps, stateful data services that can't be rescheduled cheaply. 1.0 shipped Q1 2026; you'd join mid-way through 2.0. Seed-stage, VC-funded, a few years of runway. Fully distributed across the Americas and Europe.

What you'd work on:

- Hibernation surface: containerd shims and CRUISE, our Zig-native CRIU replacement.

- Control plane: per-node DaemonSet streaming checkpoints; admission controller resizing hibernated pods in place.

- Networking and migration: eBPF/XDP at line rate; cross-node live migration to production; cross-cloud next.

You're a senior generalist. Years across the stack: assembly to frontends, hardware-near, comfortable in x86. Tests ship with the code, decisions get worked out in writing, and you measure rather than guess. Strong in Go; willing to use Zig, Rust, or C.

Bonus: eBPF/XDP, CRIU, Linux kernel internals, containerd, gVisor, live migration, or public writing in kernel/container/eBPF land. Strong systems depth and the willingness to pick up the rest is enough on its own.

Apply: https://loopholelabs.io/careers - we respond within the week (typically a few days).

Vantage | Founding Solutions Architect / FDE | NYC and Remote | Full Time

Vantage is an a16z-backed FinOps / Cloud Cost Management platform that helps 15,000+ organizations globally like Block, Canva, Temporal, Rippling, FanDuel, CircleCI, etc manage their cloud, SaaS and AI costs. As a Solutions Architect, you will work hands-on with Vantage’s most strategic and technically complex customers to ensure successful adoption and long-term value. This is a highly technical, customer-facing role focused on implementation, architecture, and problem-solving, rather than pure support or customer success.

We're a well funded Series A company and [backed by a16z, Scale venture partners and founders of Cloudflare, DigitalOcean and Segment]. The company is between 50-75 people today and scaling up quickly.

We're headquartered in NYC but US-remote friendly (sorry, we can't handle international at this time).

Wick | Applied AI Product Engineer | REMOTE | Contract (to hire) We're a funded, Atlanta-based audience intelligence platform — we sit between enterprise teams' raw market data (surveys, engagement, research) and their AI stack, giving models the market context they need to reason accurately. Looking for someone who lives in prompts. You'll own the AI experience end-to-end: write them, eval them, watch real users break them, make them measurably better. We have an AI architect. We don't need another one. You're either shipping production LLM features professionally, or you're running local models at home because you can't help yourself. Either works. Familiarity with RAG, evals tooling (Braintrust, Langfuse), and the major model providers matters. Domain background in market research or audience analytics is a bonus. Apply: [email protected]

Startup working on AI Healthcare solutions (plus some random experiments) | REMOTE(US, Pacific time zone) | Full time and project based

Full time engineering role (Remote, US person required; Pacific time zone)

Stack: C#, Python, Gemini API on Windows, lots of legacy systems/constrained enterprise environment. Health systems experience preferred. Understanding of cost effective, reliable LLM API use. Should be flexible: do PM-like work with less-technical client domain experts, solve problems end to end, willing to data cleaning and detailed work for client goals and security/compliance gruntwork, even when it's not technically elegant. Self motivated, willing to understand legacy and undocumented codebases, but also willing to take instructions.

Ideal candidate has real (pre-Claude Code) experience, but is ready to do fast iteration in post-AI world, while actually reading what the AI does. We're ok if your stack is different, if you're both technically mature and up to date on modern fast-turnaround AI-based development. Probably in the 5+ year experience range.

REMOTE anywhere, project based or initially part time: startup generalist hacker, maintain systems and websites, code one-off prototypes. Should be good enough to code without an AI in a few languages, but an effective AI harness coder. Can do a small but complete app/project end to end, including basic marketing. 2+ year exp or a new grad with a good portfolio or major project; happy to consider more experienced person. Good role for someone who's working on their own startup to pick up some side money and experience. Projects could be anything from game-like apps/novelties to voice tools to utility apps.

REMOTE anywhere, project based or initially part time: help on some more experimental mathy projects. M.S./Ph.D. in statistics, physics or related, with pragmatic programming experience. Possible projects: gaussian process modeling; designing evaluation metrics; compression; Bayesian tools for radiology imaging. May be good for a grad student part time. This is the fun stuff the founder would rather be doing himself if he had the time.

REMOTE (US person) Half-time remote admin/chief of staff type: deal with bookkeeping, compliance, communications, social media, phone calls - save us time on everything non-technical. Should be effective AI user; should have some relevant experience supporting tech business.

Please reply with a salary target. [email protected]

COVU | Data Engineer, Full Stack Engineers (Sr & Staff/Lead), Sr. Product Manager | San Francisco (Hybrid) or REMOTE (US) | Full-time

COVU is an AI-first insurtech startup rebuilding the 20-year-old legacy infrastructure of the $365B+ insurance distribution industry.

We recently announced our $16M funding round (bringing our total to ~$50M) and launched COVU OS. We aren't just slapping an "AI wrapper" onto old software; we built a task-native orchestration layer from scratch. COVU OS converts messy, unstructured insurance workflows (emails, PDFs, manual triage) into defined tasks, dynamically routing them to the right execution layer—whether that's an AI agent, a licensed human professional, or an offshore team.

We are a scrappy, execution-focused team of builders. We heavily encourage using AI tools (Cursor, Copilot, Gemini) in your daily workflow to ship code faster. If you hate spending months in "discovery" and prefer to just build and own production systems end-to-end, you will fit right in.

The Stack:

Data: Snowflake, dbt, Airflow, Python

Product: TypeScript, React, Node.js / Python backends, Cloud Infrastructure

Open Roles:

Staff Full Stack Engineer (Technical Lead): You will be a foundational technical leader shaping the architecture of COVU OS. Expect deep, architecture-level design work paired with heavy, hands-on IC contributions.

Sr. Full Stack Engineer: You will own complex product surfaces end-to-end, building out the agentic orchestration layer, user interfaces, and enterprise API integrations.

Data Engineer(Remote): You'll be the primary builder of our "Golden Policy Journal," transforming highly complex, messy carrier data into our single source of truth using Snowflake, dbt, and Airflow.

Sr. Product Manager (COVU OS): You will own the roadmap for our core operating system. We need a highly technical PM who can dive into the weeds of agentic workflows and write specs that engineers actually want to read.

Yassi|Senior Fullstack Engineer (Golang, Node.js/React, AWS) 3 days in-office Chicago

YASSI provides real-time access to vehicle title, lien, and registration data directly from U.S. state motor vehicle agencies. Unlike traditional bulk data providers, YASSI retrieves each vehicle record live at the time of request, ensuring the most accurate and current information available.

YASSI is the only provider offering an enterprise-grade solution purpose-built for real-time vehicle data at national scale. In addition, YASSI is uniquely positioned as the only platform that combines real-time vehicle record access with digital repossession title processing, enabling lenders to verify lien status and complete repo titling workflows within a single, integrated solution.

We’re rethinking how vehicle data, titling, and compliance infrastructure works— bringing real-time connectivity and transparency to an industry that’s long overdue for modernization. We are already profitable 6 years in. That is unique for a start-up.

Actively building out our engineering team in downtown Chicago and we are open to senior/staff level.

Y Combinator | Product Engineers on YC's own team | San Francisco | Full Time | $185K-$485K

I'm Ryan, an EM and engineer here at YC. We have a small, 18-person software team with no PMs -- engineers own everything end-to-end.

We build the software behind YC's $6B in investments: tools that help partners evaluate thousands of startups per batch, AI-powered apps that founders use every day, and platforms like Work at a Startup that connect candidates with YC companies. Engineers get unlimited AI tokens -- both for development and to build AI-powered products. What wouldn't you build to help founders + YC with that much firepower?

What makes this different from other roles:

* You'd learn more about startups here than you could possibly imagine. Every batch brings hundreds of founders building things across every industry, and you're right in the middle of it.

* We attend Demo Day, founder dinners, and work directly with partners and many of the companies. (They make great products!)

* We pay well, offer carry in the fund (like equity), and provide generous relocation support if you're not in SF yet.

Two roles open:

* Product Engineer -- full-stack, own the product lifecycle. Rails/React stack. Build tools that power how YC invests in and supports startups. It's a wide range, and sometimes it feels like labs-like work, other times it feels like a supersuit to power founders and our Partners like Garry and Jared.

* Community Builder and Software Engineer -- hybrid role. Run YC's talent-facing programs (meetups, tech talks, career expos) AND build the software that makes them scale. You need to be a great engineer and LOVE to build and support communities.

We're also exploring a Technical Chief of Staff role to work with one of our GPs -- someone who can think analytically, drive operations, and scale what they do with software.

Checkout more about the roles, and email me directly if you're excited to learn more about startups than you will anywhere else - [email protected]

Opendate is the operating system for live music venues — booking, ticketing, marketing, and settlement, all in one place.

Customers range from 200-cap clubs to multi-day festivals.

We're a Rails shop with real backend problems: multi-tenant ticketing at on-sale scale, financial settlements that have to reconcile to the penny, and integrations with the rest of the music industry's plumbing (Stripe, Dwolla, Seats.io, Twilio, SendGrid). If you like systems where correctness actually matters and the users are people you can go meet at a show, you'll fit in.

Stack: Rails, React/Redux, PostgreSQL, Redis, BigQuery, AWS, GCP, Docker, Terraform. Flutter on mobile. AI-first engineering culture — Cursor, Claude Code, and Copilot are part of the daily workflow, not banned from it.

100% remote within the US (no sponsorship), with optional Indianapolis or Chicago offices if you want them. Looking for 5+ years of senior full-stack experience, comfortable owning projects end-to-end and shipping to production weekly.
