Leo Cancer Care: Physicist Level III

Position Summary

We are seeking a detail‑oriented Medical Physicist with a deep technical focus on Linear Accelerator (Linac) performance, precision dosimetry, and regulatory compliance. Working within the Product Development Team, you will serve as the Subject Matter Expert (SME) for our radiotherapy delivery systems. You will drive design direction from initial concept through to regulatory compliance and the global release of new and existing medical systems.

• Lead the design and execution of complex experiments to evaluate the physical and clinical performance of medical equipment.
• Perform precise measurements and data analysis to demonstrate compliance with international medical device standards (e.g., IEC 60601-2-1).
• Act as a bridge between physics and engineering; advise on the design, development, and iterative improvement of medical devices to ensure clinical efficacy.
• Execute V&V testing protocols specifically focused on the dosimetric performance and beam characteristics of the delivery system.
• Generate high‑fidelity physics reports and technical files required to demonstrate the safety and performance of equipment for regulatory submissions (FDA, CE Mark, etc.).
• Serve as the SME for the installation, commissioning, and long‑term maintenance protocols of Linear Accelerators within the R&D environment.

• Master’s or PhD in Medical Physics, Physics, or a closely related scientific field.
• 3+ years of experience with a heavy emphasis on medical device compliance, Linac QA, and commissioning.
• Extensive experience designing and executing tests to demonstrate compliance with medical device safety and performance standards.

• Proficiency with Treatment Planning Systems (TPS) and a wide array of QA software/hardware (e.g., 3D water tanks, profilers, electrometers).
• A high degree of accuracy in performing complex mathematical calculations and physical measurements.
• Expert-level understanding of absolute and relative dosimetry protocols (e.g., TG‑51 or TRS‑398).

• Ability to translate complex physics concepts into actionable advice for both engineering teams and clinical end‑users.
• Strong problem‑solving skills with a focus on root‑cause analysis in complex electro‑mechanical systems.
• Demonstrated ability to lead projects, collaborate across multidisciplinary teams, and influence design direction.
