Senior Full-Stack Engineer

Salary: $125,000 - 125,000 per year Requirements: We bring 6+ years of experience building production web applications across the full stack, including meaningful time in a senior or staff-level role. We are highly proficient in TypeScript on both the client and server side. We have strong React experience, including hooks and modern development patterns, and are comfortable with a fast toolchain such as Vite. We have solid backend experience with Node.js and frameworks such as Fastify, Express, or NestJS, along with API design and architecture. We have deep PostgreSQL knowledge, strong data-modeling skills, and hands-on experience with an ORM such as Prisma and large-scale migrations. We understand multi-tenant data isolation, including row-level security and tenant-scoped access patterns. We make sound technical trade-offs, such as choosing between schema-per-tenant and row-level isolation, and evaluating build-versus-buy decisions. We are comfortable using Docker for local development. We communicate clearly and document our work effectively. Responsibilities: We build features end to end, spanning PostgreSQL schema and Prisma models, Fastify APIs, and the React interface. We design and improve our multi-tenant data model and access controls, including row-level security and role-based permissions. We use Zod and strong typing to keep API contracts and runtime validation reliable. We take features into production on Google Cloud Run and handle observability and live debugging. We raise engineering quality by expanding automated test coverage with Vitest and Playwright and adding quality gates to CI/CD. We review pull requests, mentor teammates, and help shape technical direction as the team grows. We apply a modern approach to end-to-end testing. We work comfortably with AI-assisted development and contribute to building agents that improve team productivity.
