About Opaxa

Opaxa is the AI agent platform that runs restaurant back-office operations. We aren't building another dashboard; we are building agents that take the work off the operator's plate and act. Our agents build schedules, place orders with distributors, audit invoices for overcharges, and draft review replies. The operator approves what matters; the rest gets done.

The Unfair Advantage: The founder owns and runs a 40-location restaurant company with over 750 employees. Opaxa's first customer is a real, operating restaurant group with real data and real stakes from day one. Your work runs in real restaurants immediately, not after a six-month hunt for a design partner. We are well-funded.

The Role

A working prototype is already built. We are looking for a founding full-stack engineer to take it from prototype to production. You will:

• Own the architecture, the agent runtime, the backend, and the integrations the agents act through (Toast, Paycom, Sysco, and more).
• Set the technical bar for the company.
• Grow the team behind you.
• Work directly with the founder, who owns product, customers, and the domain, while you own the AI and the build.

Requirements

You are a fit if you:

• Have shipped agentic systems to production (plan-and-act systems, not just chatbots or wrappers).
• Are a strong full-stack builder (Python and/or Node, Postgres, real infra).
• Use the latest AI tooling (Claude Code / Cursor) as your default.
• Want to own a whole product as the first engineer and eventually lead the team.

Tech Stack

• Frontend: React/TypeScript
• Backend: Python/Node, Postgres
• AI/Integrations: Anthropic API, integrations across the restaurant stack

How to Apply

Email colton@opaxa.ai with:

1. The most impressive agentic system you've personally shipped (what it did, what you owned, and what made it hard).
2. Your resume or relevant links.

Note: I read every application and reply. Please write your application yourself; if it is clearly AI-generated, I will pass.
