Medical Dosimetrist - Onsite
About The Position
The Medical Dosimetrist works as part of the radiation oncology treatment-planning team under the direction of Medical Physics, supporting clinical and operational oversight of the dosimetry service. The role designs or guides radiotherapy treatment planning, optimizes radiation-field arrangements and exposures, and communicates plan details to Radiation Therapists so patients are treated according to physicians’ prescriptions. The position provides technical expertise and operational leadership, including guidance and mentorship for other dosimetrists, workflow optimization, coordination of quality assurance, and collaboration with physicians and other radiation oncology team members. The role also supports continuous improvement in patient care, adoption of technology, and compliance with regulatory standards. The position is based in a patient-care environment with potential radiation exposure. It involves working with computer equipment and physics devices, and sitting, standing, and moving about. Staff must follow infection-control precautions for patients or materials requiring isolation. Staff vaccination against influenza is a condition of employment.
Requirements
- Knowledge of technical aspects of radiation oncology and medical physics sufficient to derive computerized treatment plans and communicate with Radiation Oncologists for plan approval and Radiation Therapists for plan implementation.
- Working knowledge of radiation safety and current regulations.
- Ability to work effectively as a member of a team to provide accurate radiation therapy services.
- Bachelor’s degree with a major in physical or biological sciences, medical dosimetry, or radiation therapy.
- Certification in Medical Dosimetry (CMD) from the Medical Dosimetrist Certification Board (MDCB).
- Graduate of a JRCERT-accredited Medical Dosimetry program.
- At least 3 years of recent experience as a Dosimetrist in a Clinical Radiation Therapy Department, or equivalent applicable work experience.
- Strong oral and written communication skills.
