Summary
We are looking for an enthusiastic physicist to join the Radiotherapy Physics group at the Sutton branch of the Royal Marsden Hospital for a fixed term for 7 months until 30 September 2026 (at 0.9 FTE). This post will be actively engaged in research functions and also fulfil clinical roles to allow others time for research. It is therefore suitable for someone with a research background who would like to be more involved in clinical work or a clinical physicist interested in research.
The Radiotherapy Department in Sutton has 5 Elekta linacs, an Elekta Unity MR-Linac, a Cyberknife S7 and two Accuray Radixact units. Treatment planning is performed using the RayStation treatment planning system. We have established workflows for adaptive radiotherapy (both online and plan of the day), 4DCT, and breathhold techniques.
The radiotherapy physics group consists of 40 physicists, dosimetrists and engineers and forms a substantial part of the Royal Marsden/Institute of Cancer Research Joint Department of Physics, through which we have many active research collaborations, most notably on the MR-linac which was the first in the UK to treat patients.
• The post holder will provide specialist support to all aspects of the clinical, scientific and technical
Radiotherapy Physics Service to Radiotherapy.
• The post holder will undertake research projects during dedicated time and to disseminate results
and assist with the translation of research work into the clinic where appropriate.
• The post holder has clinical and scientific responsibilities for day-to-day essential complex
treatment planning and checking and performing Quality Assurance and dosimetry and analysing
results.
• Work closely with the Principal Physicist in all areas.
The Royal Marsden NHS Foundation Trust is a world-leading cancer centre. Our role is to offer our patients the best cancer care available anywhere in the world, and to continue to make a global contribution to finding better ways of diagnosing and treating cancer. We employ over 4,500 staff in a diverse range of careers including nursing, medical, science, radiography, pharmacy, occupational therapy, finance and administrative services. We have two hospitals – one in Chelsea, London, and one in Sutton, Surrey – as well as a Medical Daycare Unit in Kingston Hospital.
At The Royal Marsden, we deal with cancer every day, so we understand how valuable life is. When people entrust their lives to us, they have the right to demand the very best. That's why the pursuit of excellence lies at the heart of everything we do.
At the heart of the hospital is our dedicated team.

• Undertake research activities associated with the adaptive and advanced Radiotherapy pathways, aligned with departmental development plans.
• Produce complex treatment plans. Carry out associated dosimetry calculations and verification measurements, in accordance with clinical prescription and agreed procedures. Analyse requirements and make complex judgements regarding treatment parameters and patient dose effects to produce the required dose distribution over the treatment volume, using computerised planning systems as appropriate.
• Participate in the commissioning of new radiotherapy treatment equipment, including the preparation and checking of complex beam data for treatment planning systems.
• Undertake both routine and complex dosimetry measurements, following procedures and/or guidelines as appropriate. Perform quality control, dosimetry and other measurements and procedures on highly complex, patient-critical treatment machines.
• Participate in the day-to-day, complex commissioning activities on new equipment installations, carefully analysing and checking measured data.
• Supervise the professional work of junior radiotherapy physics, trainees and dosimetrist staff working in areas or on projects being managed by the post holder.
• Provide practical training to physicists, medical and radiographer staff on aspects of Radiotherapy Physics, including clinical governance, ethics, audit and ISO systems.
