Senior Radiation Physicist

Senior Radiation Physicist

Location: Hybrid (regular onsite presence required)
Salary: Competitive

Seeking a Senior Radiation Physicist to support radiological safety, shielding design, and radiation transport analysis within a highly regulated, safety-critical engineering environment.
This role focuses on conducting radiological safety assessments, evaluating radiation effects on systems and electronics, supporting shielding design, and providing technical expertise to ensure risks are reduced to ALARP and regulatory requirements.

• Conduct radiological safety assessments and evaluate radiation damage risks to systems and electronic components.
• Support the design and development of radiation detection systems and associated technologies.
• Lead or support systems engineering design of primary and secondary radiation shielding solutions.
• Perform radiation transport modelling and analysis using methods such as point kernel and Monte Carlo calculations.
• Utilise radiation transport tools such as ATTILA, MCBEND, MCNP, or equivalent software.
• Provide technical guidance relating to design changes, defects, and engineering modifications to maintain safety standards.
• Develop and support ALARP justifications to underpin engineering and safety decisions.
• Contribute to shielding validation, metrology, safety studies, and technical substantiation activities.
• Produce high-quality technical reports, calculations, and supporting safety documentation.

• Degree qualified in Physics, Mathematics, Chemistry, Engineering, Nuclear Science, or a related discipline.
• Demonstrable experience in one or more of the following:
  • Radiation Physics
  • Nuclear Engineering
  • Nuclear Safety
  • Radiological Protection
  • Radiation Shielding Analysis
• Experience conducting radiological safety assessments and developing ALARP justifications.
• Knowledge of radiation transport methods, shielding calculations, and Monte Carlo modelling.
• Experience with relevant analysis tools such as:
  • ATTILA
  • MCBEND
  • MCNP
  • or similar transport/modelling software
• Strong technical reporting, analytical, and problem-solving skills.

This role offers the opportunity to work on complex radiation shielding, detector development, safety studies, and advanced modelling programmes within a multidisciplinary engineering environment, with strong development opportunities in both technical specialist and leadership pathways.

• Hybrid/flexible working arrangements available.
• Candidates may be subject to security clearance requirements due to the nature of the work.
