Senior Fullstack Developer
About the Role
At this software agency of over 80 craftsmen across Amersfoort and Rotterdam, technical direction is shaped by developers rather than managers. You will build high-performance, custom digital products for diverse clients, taking full ownership from the initial technical architecture down to automated production deployments.
On a daily basis, you navigate seamlessly between backend and frontend stacks using PHP (Symfony) and JavaScript/TypeScript (Next.js). You deploy modern cloud workloads on Google Cloud, AWS, or Azure, supported by robust CI/CD pipelines and automated testing. Scalability, performance, and developer experience guide every architectural decision you make.
Working alongside backend, frontend, and DevOps specialists, your technical seniority directly shapes the codebase and engineering practices. Taking ownership, asking critical questions, and sharing knowledge are deeply embedded in the team's culture.
