Senior Nuclear Safety Consultant

Lead the Future of Nuclear Safety

Are you ready to shape the safety standards of some of the most complex and high-profile projects in the nuclear sector? This is your opportunity to make a tangible impact on the future of nuclear, energy, defence and decommissioning. We’re looking for an experienced Senior Nuclear Safety Consultant who thrives in a technical environment and wants to lead challenging projects that matter.

Purpose & Scope of the Role

This role is central to delivering high-quality safety case assessments for nuclear facilities and operations. The successful candidate will be responsible for producing and reviewing technical documentation, conducting hazard identification and risk assessments and ensuring compliance with stringent regulatory standards. The individual will also prepare proposals, support tender submissions and oversee financial reporting for projects under your leadership.

Collaboration is key as you’ll work closely with multidisciplinary teams, engage with clients and regulators, and manage project deliverables within agreed timescales and budgets. Assignments will vary from short-term safety assessments to multi-year, multi-million-pound projects. You’ll contribute to initiatives across nuclear decommissioning, energy generation, and defence, supporting both legacy facilities and new-build developments. Expect to lead smaller projects independently while providing support on larger programmes under the guidance of Principal Consultants and Technical Directors.

Your Impact in this Position

In the short term, you’ll gain hands‑on experience in safety case delivery, regulatory engagement, and technical leadership within project teams. Medium‑term progression offers opportunities to lead complex workstreams, develop specialist expertise, and take on formal technical review responsibilities. Longer‑term, you can advance to Principal Consultant level, with options to specialise in technical disciplines or if your interests align, then you could transition into business development and strategic leadership. We’ll support you with tailored career development, exposure to varied projects and flexibility to align work with your professional interests.

Core Capabilities

• As a Senior Consultant you will apply advanced expertise in safety case development to ensure nuclear facilities meet stringent safety and regulatory standards. You will define robust strategies, lead hazard identification and apply risk assessment techniques. Your role involves integrating safety principles into engineering design and operations, influencing key decisions across the facility lifecycle. By combining rigorous analysis with strategic insight, you will deliver safety cases that are compliant, practical, and support safe, efficient, and sustainable nuclear operations.

• Adaptability is essential as you manage projects ranging from rapid hazard identification studies to complex, multi-year safety assessments. This breadth of work requires a proactive approach to learning and applying new techniques, ensuring high standards of quality throughout. You will navigate competing priorities, deliver accurate outputs and develop tailored solutions for the unique challenges presented by each assignment.

• Your communication skills will set you apart. You’ll represent the organisation in meetings with clients and regulators, presenting technical reasoning and negotiating outcomes that satisfy safety and compliance objectives. Building trust and managing expectations will be central to your success.

• Clear, concise and authoritative documentation is fundamental. You’ll produce a wide range of technical outputs, including safety case reports, radiological assessments, and supporting documentation that meet stringent regulatory and client standards. This involves structuring complex technical reasons logically, presenting evidence in a transparent manner and ensuring consistency across all deliverables. Your reports will not only demonstrate compliance but also provide clarity for decision‑makers, regulators, and stakeholders, underpinning project success. Strong attention to detail and excellent written communication skills are essential.

• As a senior team member, you will play a key role in developing junior colleagues by providing technical guidance, reviewing work for accuracy and compliance, and sharing best practices to build confidence and capability. You will support knowledge transfer through coaching, training, and feedback, helping others understand both technical aspects of safety case development and the wider regulatory and client context. By fostering collaboration and encouraging professional growth, your leadership will strengthen team performance and promote a culture of continuous learning and ensure the delivery of high‑quality outcomes across all projects.

Qualifications & Experience

You’ll need a degree in a relevant engineering or scientific discipline and substantial experience in nuclear safety case development or assessment. Knowledge of nuclear plant operations, regulatory frameworks and safety management principles is beneficial. Chartered status with a recognised professional body is desirable.
