Senior Full-Stack Engineer (Remote)

Senior Full-Stack Engineer

Job Summary

Build the scanner, dashboard, and REST API end-to-end with Next.js 16, TypeScript, and Fastify. You'll work across the whole product surface: the public PQC scanner, the customer dashboard, the Fastify REST API, and the SDKs that wrap it. We care about clean contracts — the API is the source of truth for three SDKs and a Go CLI, so the interfaces you design ripple everywhere.

What you'll do

• Ship features across the Next.js 16 / React 19 dashboard and the Fastify 5 + Zod API
• Design REST endpoints that the JS/Python/.NET SDKs and Go CLI consume
• Own data modeling in Supabase/Postgres with row-level security
• Keep the scanner, inventory, vault, ledger, and policy flows fast and reliable

What we're looking for

• Expert TypeScript across the stack (React/Next.js on the front, Node on the back)
• Solid SQL and experience with row-level security or multi-tenant data models
• You write tests as you go and care about API ergonomics
• Comfortable owning a feature from schema to UI

Nice to have

• Experience with Supabase, Turborepo, or pnpm monorepos
• Interest in security / cryptography tooling
