Radiation Oncologist

Opportunity Overview

Handshake is looking for radiation oncologists to support AI research through flexible, part-time contract work. This is not a traditional job. You’ll draw on your clinical training and hands-on experience in radiation oncology, including treatment planning, target volume and organ-at-risk contouring, dose prescription, and multidisciplinary cancer care, to evaluate AI-generated content and provide feedback that helps AI reason like a practicing radiation oncologist. The Handshake AI program runs year-round, with project opportunities opening periodically across different areas of expertise.

This is an ongoing, project-based opportunity you can take on alongside your current role.

What You’ll Do

• Use your clinical expertise to create expert-level tasks that today’s top AI models can’t solve, based on real clinical workflows such as target volume and organ-at-risk contouring, simulation CT and imaging review, dose and fractionation selection, plan evaluation, and treatment planning
• Review and evaluate AI-generated responses for clinical accuracy, patient safety, and alignment with current radiation oncology practice and guidelines
• Provide clear, structured written feedback to help improve AI model performance
• Work remotely and complete tasks at your own pace, with no set schedule or minimum hour requirement

Qualifications

• Degree and clinical training: Completed MD, DO, or equivalent medical degree
• Completed residency training in radiation oncology
• Licensure: Currently licensed to practice medicine in the United States
• Clinical depth: Working knowledge in one or more of the following areas: Contouring of target volumes and organs at risk (e.g., head and neck, thoracic, breast, GI, GU, CNS)
• External beam radiotherapy, including IMRT, VMAT, and image-guided radiotherapy
• Stereotactic radiosurgery and stereotactic body radiotherapy (SRS/SBRT)
• Brachytherapy
• Proton and particle therapy
• Palliative radiotherapy and radiation oncology emergencies
• Pediatric or hematologic radiation oncology

Additional qualifications (not required, but strengthen your application)

• Board certification or board eligibility in radiation oncology, or fellowship training in a subspecialty
• Experience at an academic medical center or comprehensive cancer center, familiarity with treatment planning systems and contouring software, peer-reviewed publications, or involvement in clinical research

Required for all applicants

• Must have US work authorization
• Strong written communication and attention to detail
• Ability to explain complex radiation oncology concepts clearly
• Ability to work independently in a remote, asynchronous environment
