Job description

You've put tool-using AI agents in production and debugged the harness yourself. Be the second technical co-founder in all but name.

A seed‑stage startup in New York runs an agentic operating system for restaurant back‑of‑house work: inventory, ordering, prep and invoices. Signed restaurants grow week over week. You'd own the product from zero to one, from the agent that drafts a purchase order to the screen where a manager approves it, with agents that move real money every day.

What you'll own

• The agent harness: context, tool execution, state, failure recovery, human approval and evals
• The product around it, from approval UIs to integrations
• Customer conversations and the roadmap, with a voice in strategy from day one

Must-haves

• You've shipped tool‑using LLM agents to production and built or debugged the harness itself
• A product spike with taste: React and full stack (infra‑only profiles won't fit)
• A founder mentality: you own outcomes, not tickets
• 1+ year of experience (roughly 1–3)
• In the New York office at an intense early‑startup pace, 9‑9‑6

Bonus points

• Something you founded or built for real users
• Early‑employee time at a fast‑scaling startup
• A strong computer science education

What's in it for you

• $150k–$220k base + 1–3% equity
• A founding seat with real influence on product and strategy

Good to know

• Full‑time, in the New York office, 9‑9‑6
• Sponsorship is limited: please tell us your exact work authorization up front
• Process: phone screen with the CTO -> take-home (an open build with AI tools) -> review plus a system-design talk without AI -> conversation with the co‑founder -> offer
