Principal Physicist - Radiotherapy (National, Home-Based)

Are you ready to embark on an exciting journey as a Principal Imaging Physicist – Radiotherapy with GenesisCare UK?

Join our nationally connected oncology physics team and play a pivotal role in shaping the future of radiotherapy imaging across our UK network of specialist cancer care centres.

Please note that this is a national role, with regular travel required to our network of centres around business needs. 

The Role

As our Principal Imaging Physicist – Radiotherapy, you will act as the national technical and governance lead for all radiotherapy imaging practice across GenesisCare UK. This is a senior, specialist Clinical Scientist role with accountability for the quality, safety, optimisation, and regulatory assurance of imaging throughout the radiotherapy pathway.

Your remit spans CT and MR simulation, image-guided radiotherapy (IGRT), adaptive radiotherapy, MR-Linac imaging, and advanced techniques including SABR, SRS, and 4DCT. You will set national standards, lead optimisation of imaging dose and quality, and ensure consistent, high-quality practice across Varian and Elekta platforms.

This role is deliberately radiotherapy-focused, with diagnostic imaging governance managed separately. You will work collaboratively across disciplines to ensure imaging remains a safe, effective, and forward-looking cornerstone of radiotherapy delivery.

What You’ll Do

• Act as the national technical authority for radiotherapy imaging, including CT simulation, kV/MV imaging, CBCT, MR-Linac imaging, and adaptive workflows

• Lead governance, quality management, and regulatory compliance for all radiotherapy imaging practice

• Own the optimisation of imaging dose and image quality, benchmarking practice against national standards and DRLs

• Design, implement, and maintain national commissioning and QA frameworks for radiotherapy imaging systems

• Lead the commissioning of new imaging equipment, acceptance testing, baseline QA, and return-to-service following major upgrades or repairs

• Provide Medical Physics Expert advice under IR(ME)R as it applies to radiotherapy imaging

• Act as the national escalation point for complex IGRT, imaging performance, and clinical risk issues

• Support capital programmes, equipment replacement, and service development in radiotherapy imaging and adaptive technologies

• Provide expert scientific and clinical advice to physicists, radiographers, and clinicians

• Contribute to national automation and standardisation initiatives within imaging QA and adaptive radiotherapy workflows

• Maintain professional breadth across the wider Clinical Scientist role to support service resilience and credibility

What You’ll Have

• HCPC registration as a Clinical Scientist (Radiotherapy Physics or Diagnostic Radiology)

• Certification as a Medical Physics Expert (MPE) or working towards certification

• Extensive post-qualification experience in radiotherapy imaging and IGRT

• Advanced knowledge of CT simulation, CBCT, kV/MV imaging, MR-Linac imaging, and adaptive radiotherapy systems

• Proven experience in commissioning and QA of radiotherapy imaging equipment and software

• Demonstrable expertise in imaging dose optimisation within the radiotherapy pathway

• Experience supporting regulatory audits, inspections, and governance reviews

• Strong technical leadership skills with the ability to influence practice without direct line management

• Excellent communication skills, able to translate complex technical and regulatory information into clear, practical guidance

• A highly organised, self-directed, and accountable approach to work

• A full UK driving license and access to a car
