About TRISERS
TRISERS is a Warsaw-based technology company building a next-generation marketplace platform that connects customers with verified service professionals — combining AI-assisted service diagnostics, real-time job dispatch, and secure online payments in one seamless product. The MVP is fully specified and the architecture documented. Joining now means real ownership: your decisions will shape the product from its first release.
Your responsibilities
- Design and deliver features across the full stack — NestJS (Node 20, TypeScript) on the backend and Next.js 14 / React 18 on the frontend
- Develop our role-based application suite (customer PWA, provider PWA, admin panel) within a single Next.js codebase
- Build and consume REST APIs; model data in PostgreSQL 16 with Prisma ORM
- Implement asynchronous workflows with BullMQ — notifications and real-time job dispatch
- Integrate the Przelewy24 payment gateway and third-party services
- Take part in code reviews and architectural decisions, working directly with the Tech Lead and Product Owner

- Strong command of TypeScript
- Solid working knowledge of relational databases (SQL)
- Good command of English (our working language)
