Job description

Do you want to build software that truly saves lives? At RaySearch, you’ll have the opportunity to influence cancer care worldwide through code, architecture, and leadership. We are looking for an experienced developer who wants to take the next step and combine advanced development with a people‑focused leadership role as a Group Manager.

Our development organization consists of approximately 160 highly engaged colleagues who build software used daily in cancer clinics around the globe. As we continue to grow, we are looking for additional group managers who want to help shape our technology, our teams, and our future.

About the Role

This role offers the best of both worlds, combining hands‑on technical work with people leadership. You will have personnel responsibility for a team of 8–12 developers while remaining an active contributor to the development of RayStation, our Treatment Planning System.

As a Group Manager, you focus on enabling your team to succeed. You support and develop your employees through regular one‑on‑one conversations, competence development, and recruitment. You will not be alone in your leadership role, but part of a collaborative management context with support from both peers and the wider organization.

In your role as a developer, you work close to the domain on technically demanding solutions and contribute to building 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 are built using 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 have a direct and meaningful impact on patient care.

Your profile

You have a strong technical foundation in .NET development and a clear interest in taking responsibility for both people and technical delivery. You are motivated by building high‑performing teams, creating structure, and contributing to a safe and sustainable working environment. With a humble and communicative leadership style, you build trust and take ownership of people‑related topics such as performance conversations, competence development, and recruitment, with support from the organization. You are self‑driven, proactive, and results‑oriented, with the ability to combine deep technical understanding with a present and engaged leadership approach.

To Succeed In This Role, You Bring

• 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 together with fluency in Swedish is not required but considered as highly meritorious.
