Senior Full Stack Engineer (Team Lead)

About the role

You'll be an engineer who happens to be exceptionally good at working with AI. Not an ML researcher, not a prompt engineer — a builder. You'll write production code across the full stack while leading a small team of engineers doing the same.

Responsibilities

• Ship full vertical slices across a TypeScript monorepo — schema migration, backend service, frontend component — in a single PR
• Drive the rebuild through its remaining phases, including the web dashboard, admin surface, mobile app, and a public API
• Build for a multi-region, data-residency-sensitive product from day one
• Integrate with the messy real world: property management systems, smart locks, payments, and a high-frequency telemetry pipeline
• Lead and mentor through code review, architectural guidance, and pairing — and set the quality bar
• Establish AI-assisted development practices that scale with the team

Requirements

• 5+ years writing production TypeScript / JavaScript
• 2+ years leading engineers — tech lead, EM, or senior engineer who genuinely owned team output
• True full-stack range: you can write a schema migration, a backend service, and a typed frontend component in the same afternoon
• Demonstrated fluency with AI coding tools — you can articulate where they accelerate you and where they quietly mislead you
• Strong relational database instincts: schema design, migrations, indexes, query plans
• Good architectural judgment — knowing when to build, buy, refactor, or ship as-is
• Clear written communication. We're async-first; decisions happen in writing
• Modern full-stack TypeScript framework experience (Nest-style backends, App-Router-style frontends)
• Offline-first mobile architectures
• Schema-first stacks with end-to-end type safety
• High-frequency event pipelines or IoT telemetry
• Multi-region or data-residency-sensitive systems
• Vertical SaaS with deep integration surface area
• TypeScript end to end, in a strict monorepo
• A modular backend, a modern App-Router web app, an offline-first mobile app, and an edge layer for public-facing surfaces
• Managed Postgres with row-level security and an ORM that owns the schema
• Background jobs on a managed queue
• End-to-end type safety from database row to frontend form, validated by a single shared schema layer

Qualifications

• Small team, high ownership. You own features end to end, including their failure modes
• AI-first development, structurally. The codebase is deliberately built for AI comprehension: narrow module boundaries, strict types, schema-first data flow. AI tooling is part of the dev loop, not a side project
• Types over tests, but tests where it counts. End-to-end type safety catches most bugs at compile time. When we test, it's integration tests against real infrastructure — no mocked databases
• Real engineering hygiene. No any, no silenced warnings, no logic in controllers, no auto-save forms. The rules exist because they keep the codebase legible to humans and agents
• Async-first. Decisions happen in writing so they survive past the meeting
