Job Technologies

Your role in the team

Your focus is on product development, system stability, and architectural decisions within your own domain.
With us, you develop software that makes a real impact - not just code.
We are a product-driven company that works with agile methods and operates a highly scalable system that influences real processes in urban areas on a daily basis.
You work for our product and not as a contract developer – and that is precisely why you can fully focus on what truly matters: sustainable solutions, high quality, and measurable impact.
Our strongest features come from the engineering team itself because we don't stifle ideas, but foster them.
R&D initiatives are regularly integrated into the core product.
We are actively working in parallel to reduce legacy and technical debt in order to deliver a stable, future-proof system in the long term.
You are responsible for a complete area of our digital parking system - a product that operates on over 350,000 parking spaces and processes more than €100 million in parking volume annually.
You develop robust, maintainable software in a system that had only 1.5 hours of downtime in 2025.
You make technical design decisions, solve complex problems, and integrate new hardware interfaces into our Parking OS.
You work closely with product management and POs, actively challenge the status quo, and significantly influence product development.
By conducting testing, code reviews, and adhering to standards, you ensure long-term product and code quality.
You support us in reducing legacy and technical debt and bring in new ideas that can be directly incorporated into our product.
