Software Engineer

Will you help lay the foundation for a future-proof platform that truly supports mental healthcare professionals?At HCI, we are building a new, complex Electronic Health Record (EHR) system for mental healthcare (GGZ). This is not a greenfield side project, but software that will soon be used daily by thousands of healthcare professionals. The current system remains operational, so you’ll be building the new platform while the business continues as usual. Our ambition: go live within 2–3 years. Some say it can’t be done. We believe it can.What will you do At HCI CRS, you develop software that makes a real impact in mental healthcare every day. You ensure that practitioners can rely on systems that are stable, secure, and user-friendly. As a Senior Software Developer, you contribute to building a new EHR SaaS platform and help create solutions that support thousands of healthcare professionals.You balance long-term technical improvements (architecture, integrations, performance) with short-term functional needs, while safeguarding the reliability required in a mental healthcare environment.In this role, you combine hands-on development with strategic thinking around technical innovation and the professionalization of our development practices. You act as a sparring partner for fellow developers and product management, contributing to the evolution of our (agile) engineering practices.In short:You help build a new platform (C#/.NET, Azure, microservices) to replace the current EHRYou mainly write new code (±90%), this is not a bug-fixing factoryYou work on integrations (APIs) with other healthcare systems — stable and secure, because it simply has to workYou contribute to architectural decisions that will still make sense five years from nowYou translate feedback from mental healthcare professionals into concrete product improvementsYou help your colleagues grow (code reviews, sparring, knowledge sharing, growth mindset)You’re not here to just tick off tickets. You’re here to build something that needs to be right — technically and functionally. And yes, sometimes that means solving complex puzzles while everything keeps running. If that energizes you, we should talk.Where will you work HCI CRS is one of four business units within Health Cloud Initiative (HCI) — a network of 250 colleagues with a strong focus on healthcare.
