Senior Full-Stack Engineer

Remote (US / EU time zones)Full-timeSenior

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
