Senior Scientific Software Engineer

Join us in pioneering breakthroughs in healthcare. For everyone. Everywhere. Sustainably.

Our inspiring and caring environment forms a global community that celebrates diversity and individuality. We encourage you to step beyond your comfort zone, offering resources and flexibility to foster your professional and personal growth, all while valuing your unique contributions.

In our Image Reconstruction team, we develop state‑of‑the‑art algorithms and software for cone beam computed tomography (CBCT) image processing and reconstruction. Varian’s treatment delivery systems use our software to reconstruct 3D and 4D images of the patient’s anatomy. The images are nominally used for patient positioning on the treatment machine, with recent advances in image quality opening up their potential to be used also for replanning and adaptive radio‑therapy.

Our work focuses on further optimizing 3D and 4D image quality and developing innovative and product‑oriented algorithms in Varian’s clinical solutions.

In a team of six highly competent scientists and software engineers, you will be responsible for the design and implementation of algorithms in the CBCT image reconstruction domain. Particular focus will be on enhancing performance of the algorithms both in terms of execution speed and image quality.

• Implement new methods, conduct feasibility studies and integrate selected algorithms in Varian’s product line
• Use parallel programming (GPU) to enhance performance of existing reconstruction algorithms
• Perform imaging experiments in the lab for testing, proof‑of‑concept and troubleshooting investigations
• Document design and test specifications of CBCT reconstruction algorithms
• Assist product support engineering (PSE) in troubleshooting
• Conduct literature research in the CT/CBCT reconstruction domain

• M.Sc. or PhD in Computer Science or a related technical discipline
• Familiarity with high‑performance computing
• Expertise in compiled programming languages (C++ and CUDA; other languages are a plus)
• Proficiency with modern version control systems (e.g., Git)
• Analytical and highly structured mind
• Strong sense of teamwork and source code ownership
• Fluency in spoken and written English, German is a plus
