Description

Opaxa is the AI agent platform that runs restaurant back-office operations. Agents build the schedule and push it to action, place the order with distributors, audit the invoice for overcharges, and draft the review reply while the operator approves what matters. Opaxa is hiring a founding full-stack engineer to take a working prototype from prototype to production. The role involves owning the architecture, the agent runtime, the backend, and the integrations the agents act through (Toast, Paycom, Sysco, and more), setting the technical bar, and growing the team behind you. You would work directly with the founder (who owns product, customers, and the domain) while you own the AI and the build, with additional engineers and account managers to be hired within the first year. You are a fit if you have shipped agentic systems to production (plan-and-act, not chatbots or wrappers), are a strong full-stack builder (Python and/or Node, Postgres, real infra), and use the latest AI tooling (Claude Code / Cursor) as your default. Stack: React/TypeScript, Python/Node, Postgres, the Anthropic API, and integrations across the restaurant stack. To apply: email colton@opaxa.ai with the most impressive agentic system you’ve personally shipped (what it did, what you owned, what made it hard) plus your resume or links. Application must be written by you; if clearly AI-generated, they will pass.
