Radiotherapy Dosimetrist

The closing date is 02 February 2026

We are looking for an enthusiastic and motivated person to join our radiotherapy treatment planning team, providing a radiotherapy physics service to the Sussex Cancer Centre. The successful applicant will have a BSc in a science‑related subject, a radiography degree, or an equivalent qualification. Experience is desirable, but not essential as in‑service training will be given.

The Radiotherapy Physics section has nearly 30 staff providing scientific, technical and engineering support to the Sussex Cancer Centre at the Royal Sussex County Hospital and its satellite units in Preston Park (Brighton) and at Eastbourne District General Hospital. The post holder will be based at one of these sites, but will be expected to travel to the other sites on a rotational basis.

Treatment delivery equipment comprises four Elekta VersaHD linacs, two Accuray Tomotherapy machines (at Preston Park), and an Elekta Flexitron HDR afterloader. There are two dedicated Philips CT scanners (at RSCH and EDGH) with 4D capability.

Clinical processes are managed within a predominantly paper‑free environment using the Elekta Mosaiq Oncology Information Management System. Treatment planning is primarily performed on RayStation, alongside brachytherapy planning on Elekta Oncentra and Tomotherapy planning on Accuray's Precision platform.

Main duties of the job

The principal aspects of the work are producing routine and complex radiotherapy treatment plans and the manufacture of patient positioning devices for radiotherapy treatment. Duties also include a range of other treatment planning, mould room and dosimetry activities.

Possession of excellent communication skills is essential, and you should enjoy working collaboratively within multi‑disciplinary teams. Computer literacy and the ability to perform a variety of tasks accurately and efficiently in the demanding conditions of a busy clinical environment are essential.

• Make other patient specific treatment aids such as paraffin gauze bolus, wax blocks, lead or low melting point alloy electron cut‑outs, using a range of manufacturing techniques.
• Assess patients attending the Mould Room for individual support needs, such as difficulty in feeding, and liaise with the Head and Neck Cancer Support Team regarding these needs as necessary.
• Arrange appointments for patients to ensure that they receive treatment when planned, liaising with medical and radiographic staff.
• Perform routine QC checks on computerised treatment planning systems according to departmental protocols as part of the Quality System.

• Maintain up to date knowledge and be aware of the latest scientific, technical and clinical developments affecting treatment planning and delivery.
• Attend suitable internal and external seminars, meetings and courses as part of training and personal development and to further the work of the Medical Physics Department and SCC, reporting back by appropriate oral and/or written means.
• Ensure all activities are carried out within a quality framework and conform to statutory regulations, approved Codes of Practice, and Local safety Rules.
