About The Position

This is a lead physicist role in a federal radiation oncology service located in San Antonio, Texas. The position involves owning the quality management and radiation safety programs, mentoring a junior physicist, and performing clinical work. The facility is a large federal Radiation Oncology service within the South Texas Medical Center, treating a high-volume veteran population. The service is accredited and practices to ACR, ASTRO, and AAPM standards, with resident teaching on site. Two physicists cover the service, sharing the workload and maintaining a clinical pace.

Responsibilities

• Serve as lead physicist for the radiation oncology service, setting physics priorities and coverage alongside the service chief
