Senior Full-Stack Web Developer
As a Senior Full-Stack Web Developer, you will design, develop, and maintain a demanding edge-to-cloud software platform for fully autonomous parking operations. You will work on production systems that run both on edge devices and in the cloud, with real-world, business-critical usage.
Your responsibilities include developing full-stack features using TypeScript, Node.js, React, and PostgreSQL, designing and implementing well-structured HTTP APIs and system integrations, and ensuring performance, reliability, and maintainability in production environments. You will take ownership of the technical design and implementation of the solutions you build, from concept to deployment.
You will collaborate closely with other senior engineers in a small, highly skilled product development team. The role is strongly hands-on and involves working across frontend, backend, and cloud infrastructure.

The environment emphasizes autonomy, technical quality, and end-to-end responsibility. You will work with modern technologies, high expectations, and a product where software reliability, scalability, and long-term maintainability are critical.
