Founding Engineer – AI for Procurement

Competitive programmer, quant, or a founder who gave it a real shot? Build an AI workforce for an industry that is begging for a real product.

A seed-stage startup in San Francisco builds AI agents for direct procurement at large manufacturers, and is already closing substantial enterprise contracts. It's an unglamorous industry with a huge need, and a small, driven team. You'd own everything from the first customer conversation to deployment, own an enterprise account, and grow into a team lead.

They're hiring 3 founding engineers.

What you'll own

• Backend-leaning full-stack work on LLM agents, tool use and evals
• Deployments at enterprise customers, end to end
• An enterprise account of your own, and later a team

Must-haves

• Backend-leaning full stack in Python, TypeScript, Java or C++, with LLM agents, tool use and evals (front-end-only won't fit)
• A clear technical spike: ICPC, USACO, IOI or olympiad results, quant work, or a startup you founded
• 1+ year of experience (roughly 1–4); exceptional new grads are welcome
• Based in the US and no visa sponsorship needed now (US citizen, green card or, for example, STEM OPT)
• In person in San Francisco, 9-9-5

Bonus points

• Something you built unprompted that has real users
• Agent evaluation and guardrail work

What's in it for you

• $160k–$180k base + 0.5–1% equity
• Founding-level ownership and a path to team lead

Good to know

• Full-time, in person in San Francisco, 9-9-5
• Process: intro call with a co-founder short screen-recorded take-home (AI tools allowed) technical conversation paid work trial of two to five days offer

When you apply, please include

• Your CV (PDF), your LinkedIn URL, and GitHub if you have one
• Your contest or quant results, or the startup you founded and what happened
• Why you'd join a three-person company in an unsexy space like procurement (an honest answer is the best answer)
• Your current location, and confirmation that in person in San Francisco works for you
• Your work authorization status
• Your base salary expectation, your notice period, and any other interview processes you're in
