* with a senior team that values clarity, craft and delivery.
Hard problems, clean engineering and real impact: you work on AI, data and software that reaches real users, with mentorship and code reviews from day one.
We’re looking for Senior Backend JavaScript Developers to help us ship our AI platform. You’ll design Node.js and NestJS services, model the data behind them, and work with a team that values clarity, craft, and delivery.
Backend Product Development
Own features end to end, from API contract to database schema to what runs in production. You'll write TypeScript services in NestJS, model data with MikroORM and PostgreSQL, and expose clean, typed endpoints the frontend can build on with confidence.
Clean, Typed APIs
Design REST endpoints with contracts that hold. Validation at the boundary with Zod, predictable error shapes, and versioning that doesn't break the clients you already have.
Solid Data Modelling
Entities, relations, migrations, and queries that stay fast as tenants grow. PostgreSQL and MikroORM, with indexes and transactions chosen on purpose, not by accident.
Reliable API Foundations
Authentication with Auth0 and JWT, permission checks on every route, background jobs on BullMQ and Redis, and logging good enough to debug a live incident.
Ship Together
Work in short cycles with frontend, design, and infrastructure in the same room. Review each other's pull requests, agree the contract before the code, and keep the develop branch deployable.
Quality, Proven
Unit and integration tests for the logic that matters, CI green before merge, and features that behave the same in staging as they do for the first customer who opens them.
You’ll work alongside senior colleagues on innovative projects, across AI, data, product, and delivery, shipping work that reaches users while leveling up every week.
