Job summary

Modo is looking for a founding engineer to shape product, company, and engineering culture from day one. You will write production code and drive customer-facing features, with an outsized role in roadmap and architectural decisions.

You’ll own features end-to-end, collaborate with pilots, and work across the stack (TS/React/Next.js/Postgres/Electron). Expect hands-on delivery, fast feedback loops, and a path to leadership as we scale in SF.

Qualifications

• Experience shipping full-stack production-ready products in fast-moving environments.
• Strong with TypeScript, React, Next.js, backend APIs, and Postgres.
• Comfortable building across web and desktop (Electron, Tauri, or similar).
• Has built LLM-powered features in production.
• Production habits: CI/CD, testing, observability, pragmatic system design.
• Native with AI coding agents (Claude Code/Codex).
• Obsessive about customer needs, not just abstract users.
• Comfortable debugging, writing tests, talking to customers, and jumping on a pilot call.

Responsibilities

• Talk to customers and join pilot calls.
• Turn feedback into product changes the same week.
• Influence the roadmap directly.
• Help close deals by building what matters fast.
• Own features end-to-end, from prototype to production.
• Ship production code to real pilot customers in your first weeks.
• Build the core product surfaces: employee-facing guidance UX and manager dashboard.
• Work across the stack (TypeScript, React, Next.js, Postgres, Electron/Tauri).
• Wire up LLM features that actually work in production, not just in a demo.
• Set up the telemetry and eval systems that make our insights credible.
