- Comfortable owning a customer-facing feature from idea to production without a lot of hand-holding
- Based in the US — SF Bay Area or LA strongly preferred
Why Cora:
- Work on cutting-edge applied AI: voice agents, knowledge graphs, multi-agent systems, evals, simulations, and more
- Real users, real impact, high autonomy
- Fast, fair interview loop — no BS
- Fully covered healthcare for you and your dependents
- 401(k) plan
- Flexible time off

Our customers (real customers you've heard of) have thousands of packaging assets spread across dozens of markets, languages, regulations, and brand standards.
Every change needs to be reviewed before launch. Humans currently do most of that work.
We are automating it. The challenge isn't generating text. The challenge is building systems that can be wrong almost never.
We're looking for:
- Forward Deployed Engineers who enjoy sitting with customers, figuring out what's actually broken, and building solutions faster than a roadmap ever could.
- Applied AI Engineers who obsess over retrieval, evaluation, orchestration, reliability, and all the ways AI systems fail in production.
- Account Executives

YC is hiring Product Engineers to build the future of YC -- and increasingly, software for startups everywhere.
We're a team of ~20 engineers building everything from Work at a Startup and Demo Day to investor software, founder tools, AI systems, and new open source projects. We don't have PMs. Engineers talk to users, decide what to build, and ship quickly.
Some of what we've been building:
* New products: GStack rethinks the software stack for an AI-native world. GBrain explores persistent memory and knowledge systems for AI. Paxel and other AI-powered products help founders—and increasingly everyone else -- build software and companies faster.
* Products at scale: We build and operate Work at a Startup (2M+ candidates, 1000s of early startups), Demo Day, our investor marketplace, SAFE signing, founder CRM, and the software that powers YC itself.
* Data: YC has over 20 years of proprietary startup data. We're applying it to how we think about the future of YC's batch, fundraising tools, hiring, recommendations, and entirely new ways to help people start and grow successful companies.
AI has fundamentally changed how we build software, and we're looking for engineers who are already experimenting with coding agents, MCP, LLMs, context engineering, evals, developer tooling, and whatever comes next. Our stack includes Rails, React, Postgres, Python, TypeScript, LLM APIs, and plenty of experimental infrastructure, but we're much more interested in great builders than expertise in any particular framework.
We're in person in San Francisco (Dogpatch). You'll work closely with founders and alongside people like Garry, Jared and Diana, helping define how YC—and startups more broadly—build software in the AI era.
We offer competitive compensation, carry in the YC fund, and a small, high-autonomy engineering team.

Kinelo solves "context myopia": autonomous and semi-autonomous AI agents don't know what they don't know, so they can't search or find the background information required to accomplish tasks accurately and effectively. The result looks like slop but it's not due to model performance, more due to workflow integration. From there, we're rapidly moving into organizing humans together with autonomous "AI coworkers" into workflows that span both. Our goal is to change how organizations are run and structured.
We're hiring for two roles right now:
- Product Engineer / Senior Software Engineer (https://job-boards.greenhouse.io/kinelo/jobs/4205846009) -- do you have the software engineering wisdom not yet encoded in an LLM? and do you have product sense and the willingness and desire to think several steps ahead in the market?
- Founding GTM Lead (https://job-boards.greenhouse.io/kinelo/jobs/4215784009) -- there's no playbook for go-to-market in the category we're creating + the landscape is changing daily. Come architect a strategy and then move mountains to execute on it and help us grow insanely fast.
Competitive salary, meaningful (~first batch of hires) equity, founder previously exited to Apple, strong fundraising history (~$10m).
Please email us at jobs@kinelo.com.
If you want to stand out:
- For the product engineer role, tell us how you think the job of a software engineer is changing.
- For the GTM role, tell us about a time you got massive results with limited resources, all through your ingenuity, creativity, and hard work.

Conductor lets builders run teams of coding agents. We're a small team, we recently announced our $22m Series A, and we're looking for exceptional software engineers and designers to join us.
We are a new robotics company based in Palo Alto, California, building wearable robotic devices that improve the endurance of humans on foot.
Our first product is a lightweight, bilateral hip product that reduces the physical cost of carrying heavy loads over distance, allowing personnel to move farther, carry more, and arrive at the objective less fatigued and more effective. The company is early but already operating in the field, with a direct feedback loop in the most demanding conditions imaginable.
We are backed by Y Combinator and a group of leading deep-technology investors.
We've recently moved to the Bay area to grow the team, and are hiring three lead engineers who will own product/ their domains, and have full authority with no inherited design decisions and no one between them and the problem. What you build will be worn in weeks by real users:
- Mechanical: structures, joints, actuator integration, ruggedness
- Firmware: real-time motor control, sensor fusion, embedded systems
- Software: device-to-cloud telemetry, test infrastructure, user apps
Shoot me (founder) a text (+1 857-327-3414) and I'll tell you exactly what we're building :)
Roles:
- Senior Software Engineer, 3D Measurements
- Engineering Manager, 3D Measurements

At Shepherd, we're pursuing the most ambitious technical vision in commercial insurance: fully autonomous underwriting. Shepherd is an AI-native commercial insurance platform transforming how high-hazard industries get covered.
The infrastructure behind the AI boom (data centers, semiconductor fabs, renewable energy assets) has to be built and insured, but traditional carriers weren't built for this speed. We built Shepherd to solve that.
We just recently announced our $42M Series B! That brings our total funding to over $60M — led by Intact Private Capital, the investment arm of one of the largest insurers in the world. Intact is not only our lead investor but also a carrier partner, a testament to the confidence the incumbent industry has in what we're building.
We’re looking for product-minded, high ownership engineers to join our team! We’re hiring various mid-level, senior-level and staff-level engineers. Engineers own projects end-to-end so full stack ability is expected.
