As a Group Manager, you focus on enabling your team to succeed. You support and develop employees through regular one‑on‑one conversations, competence development, and recruitment.

In your developer role, you will work closely with the domain on technically demanding solutions and help build robust, scalable systems. Depending on your background, you will work across backend, frontend, or full‑stack development, contributing to architecture and system design. Our solutions use modern architectural principles such as Domain‑Driven Design, event‑driven systems, and asynchronous communication in an environment where security, data integrity, and reliable system communication are critical. Your technical expertise will directly impact patient care.

Your profile

• A Master's degree in Engineering or an equivalent academic background
• At least 7 years of experience developing complex products using .NET
• A genuine interest in people leadership and personnel responsibility
• Experience from leadership roles or informal leadership in development teams
• A strong drive to contribute to and further develop the engineering organization
• Fluency in English, written and spoken
• Previous experience in a role with formal people management responsibility, where fluency in Swedish is a plus but not required
