Full-Stack Engineer
TypeScript · Node.js/NestJS · Next.js · React/React Native
About the role
We’re looking for a product-minded full-stack engineer fluent in TypeScript to design and operate services in Node.js (NestJS), shape data models and integrations, and ensure reliability and performance. You’ll also contribute to user-facing features in React/Next.js and React Native to ship end-to-end functionality with high quality.
What you’ll do
- Design and implement scalable NestJS services (REST/gRPC), data models, and third-party integrations
- Model and optimize databases (SQL/NoSQL), queries, caching (Redis), and background jobs
- Drive reliability & observability: testing, metrics, tracing, logging, CI/CD
- Own features end-to-end: plan, estimate, implement, test, document, and monitor
- Collaborate with Product & Design to scope MVPs, iterate quickly, and measure impact
- Ship interfaces across web and mobile: responsive UIs in React/Next.js and native experiences in React Native
You’ll thrive here if you have
- 3–6 years building production backends with TypeScript and Node.js/NestJS (auth, testing, observability, scalable APIs)
- Database fluency (SQL/NoSQL) and ORMs (e.g., MikroORM, TypeORM or similar), plus cloud basics (AWS/GCP)
- Strong front-end skills with React and Next.js (SSR/SSG, routing, data fetching)
- Mobile experience with React Native (navigation, native modules, app store delivery)
- Solid testing habits and CI/CD workflows; you value readable, maintainable code
Nice to have
- Event-driven architecture and WebSockets/real-time communications
- Production hardening: logging, metrics, tracing, OpenTelemetry, on-call
- UI systems (design tokens, Storybook) and performance profiling
Our stack
- Backend: Node.js, NestJS, REST/gRPC
- Data: Postgres/MySQL, Redis; ORM (MikroORM/TypeORM)
- Infra: Docker, CI/CD, AWS/GCP; monitoring with modern APM/logging tools
- Frontend: React, Next.js, React Native, TypeScript
How we work
- Small, cross-functional squads with weekly planning and async docs
- Pragmatic testing, code reviews, and continuous delivery
- Autonomy with accountability - ship, measure, iterate
Benefits
- Possibility of additional benefits aligned with long-term company success
- Work with passionate people advancing sustainable, inclusive, livable cities
- Direct impact: your features improve daily commutes and help city planners decide better
- Culture of autonomy, feedback, and ownership - your ideas shape the roadmap
- Be part of the change: help drive the digital transformation of urban transport
- Personal learning budget and tickets to top mobility, urbanism, and open-data events
