We'll inspire and empower you to deliver your best work so you can evolve, grow and succeed - today and into tomorrow. With more than 55,000 people in 40+ countries, we offer an exciting range of opportunities to develop your career within a supportive and diverse team who always strive to do the right thing for our people, clients, and communities.

People are our greatest asset, and we offer a competitive package to retain and attract the best talent.

In addition to the benefits you’d expect, UK employees also receive free single medical cover and digital GP service, family-friendly benefits such as enhanced parental leave pay and free membership of employee assistance and parental programmes, plus reimbursement towards relevant professional development and memberships. We also give back to our communities through our Collectively program which incorporates matched-funding, paid volunteering time, and charitable donations.

Work-life balance and flexibility is a key focus area for us. We’re happy to discuss hybrid, part-time, and flexible working hours, patterns, and locations to suit you and our business.

About the Opportunity:

The Assurance, Technology and Regulation (AT&R) performance unit is a critical part of the Technology and Consulting business. AT&R has been providing critical services to the nuclear industry for over 60 years.

Do you want to play a vital role in existing and new defence and civil nuclear programmes in the UK, and want to provide key physics support to both defence and civil nuclear sectors?

We are looking for a full-time Senior Physicist/Consultant to join our Reactor and Radiation Physics Team at our Birchwood office in Cheshire, to carry out independent nuclear safety and technical assessment of nuclear submarine propulsion plants, and support criticality and shielding safety case development in support of the civil nuclear sector and other safety-critical infrastructure.

The NS&E department provides the technical capability, within defined subject matter areas, in support of our Independent Assurance (IA) function, which is a crucial activity demonstrating to regulators and other key stakeholders that technical proposals and activities have been subject to independent scrutiny and challenge.

Our expertise of over 30 experienced scientists and engineers covers all aspects of nuclear safety, including design studies and modelling. Our range of experience spans from advice at the concept stage through the whole lifecycle of Reactor Plant.

Key Responsibilities include:

• Assessment of safety cases.
• Assessment of design technical cases.
• Providing formal independent nuclear safety and technical assessment of documents relating to the Physics aspects of nuclear propulsion and delivering the assessment output in formal letters, which may be presented to relevant safety and technical committees.
• Performing assurance activities (Physics trails and testing).
• Contributing to Research projects in reactor physics and associated technologies.
• Representing us at safety and technical meetings with clients, the plant authorisee, designers, and safety case authors.
• Applying your personal skills and experience to other projects carried out by us, including shielding and criticality assessments for clients in the civil nuclear industry.

Relevant background experience should include some or all of the following:

• Criticality and radiation shielding assessment.
• Reactor Plant Physics analysis and performance.
• Independent nuclear safety assurance including safety assessment of relevant safety cases and technical assessment of reactor designs.
• Criticality safety analysis.
• Radiation shielding.
• Mathematical methods and modelling.

You will also have experience of some of the following:

• Criticality safety, reactor physics, or shielding analysis.
• Submarine reactor design and safety case.
• Civil reactor design and safety case.
• Shielding and radiological safety case development and assessment.
• Use of physics analysis codes.
• Understanding of the UK Regulatory and Assurance Environment.

Our Culture:

Our values stand on a foundation of safety, integrity, inclusion, and diversity. We put people at the heart of our business, and we genuinely believe that we all succeed by supporting one another through our culture of caring. We value positive mental health and a sense of belonging for all employees.

We aim to embed inclusion and diversity in everything we do. We know that if we are inclusive, we’re more connected, and if we are diverse, we’re more creative. We accept people for who they are, regardless of age, disability, gender identity, gender expression, marital status, mental health, race, faith or belief, sexual orientation, socioeconomic background, and whether you’re pregnant or on family leave. This is reflected in our wide range of Global Employee Networks centered on inclusion and diversity.

We partner with VERCIDA to help us attract and retain diverse talent. As a Disability Confident employer, we will interview all disabled applicants who meet the minimum criteria for a vacancy. We welcome applications from candidates who are seeking flexible working and from those who may not meet all the listed requirements for a role.
