What a TypeScript developer does on our teams
A TypeScript developer on our team owns a feature across the whole stack and uses the type system to keep it coherent: a Prisma or Drizzle schema, a NestJS or Node.js service with Zod-validated inputs, a tRPC or GraphQL contract and a Next.js screen that cannot compile against the wrong shape. On Paint Nite, a national events platform rebuilt beside its legacy system, five engineers delivered eight NestJS services behind one GraphQL gateway and three Next.js apps in a Turborepo monorepo, with 754 automated test files run on every pull request. On LogFish, a fishing log and social app, the backend is seven NestJS microservices behind a GraphQL gateway with RabbitMQ for events, serving React Native apps and a Next.js web platform from the same typed API.
How we assess TypeScript developers
- Type-level judgement: generics, discriminated unions, inference at API boundaries and when a type is doing too much work
- Full-stack design: schema, service and screen for a realistic feature such as team billing with usage limits, with types shared across all three
- Production habits: migrations, structured logging, error contracts, feature flags and what they do when a deploy fails
- Sample task: build a small Next.js and NestJS feature in a Turborepo workspace with Zod validation and Vitest and Playwright tests in four hours, then walk us through the trade-offs

SolasEnterprise · OperationsHiring TypeScript developers, answered.
Front end, back end or both?
Both. A TypeScript developer on our team ships the Next.js screen and the NestJS or Node.js endpoint behind it. For a front-end-only role see our React or Next.js developers; for backend-only see our Node.js developers.
Which ORM and API style do you use?
Prisma or Drizzle on PostgreSQL. tRPC inside a monorepo where client and server ship together; GraphQL or REST with Zod-validated contracts when third parties consume the API.
Can they migrate our JavaScript codebase to TypeScript?
Yes. We turn on strict mode file by file, starting with the shared models and API boundaries, and keep every pull request shippable so the migration never blocks a release.
