About The Position

Memorial Sloan Kettering Cancer Center (MSK) is seeking a Clinical Radiotherapy Physicist to join their Radiation Dosimetry Core in Manhattan. This role will support commissioning, quality assurance (QA), advanced dosimetry, and clinical external beam radiotherapy physics across MSK sites. The position is available at two levels: Physicist I for candidates with a master's degree and less than 3 years of post-training clinical experience, and Physicist II for candidates with 3-5+ years of experience. As part of the Radiation Dosimetry Core, you will contribute to the development, implementation, and maintenance of MSK's QA and dosimetry programs across multiple clinical sites. Responsibilities include performing routine and advanced QA for linear accelerators, CT simulators, and associated systems, maintaining QA datasets and documentation, supporting external beam radiotherapy physics operations, patient-specific QA review, and daily QA processes. You will also support the commissioning of new clinical equipment/software, evaluate and implement emerging QA technologies, maintain detailed records and technical procedures, and collaborate with radiation oncologists, therapists, dosimetrists, and physicists, providing training and serving as a resource. Professional growth is encouraged through participation in workshops, lectures, meetings, and continuing education.
