Job overview
We are pleased to offer an excellent opportunity in a senior role at our friendly and forward‑thinking radiotherapy physics team at North Middlesex Hospital in North London. The role is as a Band 8B Principal Radiotherapy Physicist, with specific section lead responsibility for Radiotherapy Imaging and Radiation Protection.
If you have expertise in radiotherapy physics and are looking for a new challenge or the next step in your professional development, this is the ideal post for you. The department has three 8B roles, including this one. Once the post is filled, all of the Principal Physicists will be able to express interest in taking on the Deputy Head of Radiotherapy Physics role at Band 8C.
Our radiotherapy service is equipped with Varian TrueBeam and Halcyon linacs, with Varian Eclipse used for all treatment planning. We have recently commissioned a TrueBeam equipped with HyperSight and AlignRT for SGRT. We also have an XStrahl treatment unit for superficial radiotherapy. Ongoing developments include knowledge-based planning, QA automation with RadMachine, planning with RapidArcDynamic, and lots more besides.
The team includes 10 clinical scientists (including this post), 6 dosimetrists, and 6 engineering and technical staff, creating a collaborative and well-supported working environment.
Flexible working is supported across the Trust, with a hybrid model combining on-site and remote working.
Main duties of the job
The Principal Physicist will support the Head of Radiotherapy Physics in ensuring the safe, effective, and compliant delivery of the Radiotherapy Physics Service. This will include a significant role in the clinical implementation, optimisation, and governance of Image-Guided Radiotherapy (IGRT) and associated imaging technologies, including surface-guidance.
A key responsibility of the post-holder will be to act as a clinical link between treatment planning, machine performance, and treatment delivery, ensuring that planned treatments are accurately and safely translated into practice. The role involves close multidisciplinary working with therapeutic radiographers, contributing to the development and evaluation of imaging protocols, verification strategies, and adaptive radiotherapy workflows, and supporting decision-making during treatment delivery.
The post-holder will provide specialist scientific leadership in the development and integration of imaging within radiotherapy pathways, including IGRT, motion management, and image-led treatment adaptation, while also maintaining responsibilities in radiotherapy imaging and radiation protection.
The post-holder will provide expertise with respect to the Ionising Radiation Regulations and the Ionising Radiation (Medical Exposure) Regulations. This will include managing departmental local rules and radiation risk assessments, investigating incidents and reporting these appropriately.
