Full Stack Engineer

We currently have a job opening for a pragmatic and hands-on Full Stack Engineer who loves shipping fast and working across a modern TypeScript ecosystem. We build in Cursor and optimize our development process for AI-assisted engineering — most of our code is generated with AI, and your role is to guide it, validate it, and deliver production-quality features quickly.
This is a hybrid position in Warsaw (2 days per week on-site) in which you’ll work across our stack (Nest.js, Next.js, React Native, Neon/Postgres, AWS), closely collaborating with PMs, product, and users. Ownership, clarity, and iterative delivery matter most.
Skills required
Strong proficiency in TypeScript is a must. Other than that we look for experience with Nest.js (backend), Next.js (frontend), React Native (mobile), Postgres/Neon, and AWS (or equivalent)
Java experience is a plus, but not required
Strong understanding of CI/CD, testing strategies, performance, security, observability, and production readiness
Experience building end-to-end functionality in production systems, ideally with production accountability
Comfortable working with AI-assisted development (Cursor) and evaluating, refining AI-generated code
Product mindset and entrepreneurial spirit: you know how to take ownership, and you deliver tangible value and solve actual user problems through iterations
Clear and concise communication with PMs, designers, and stakeholders
Fluent English and ability to commute to our Warsaw office are a must
