Job Context & Challenges

Safe, secure and sustainable site stewardship is Sellafield Ltd’s priority, with this role integral in supporting the maintenance of the highest standards in SHEQ performance whilst enabling high hazard risk reduction.

Sellafield is a uniquely complex, high‑hazard nuclear environment where disciplined, coherent and assured management arrangements are essential to safe, secure and sustainable site stewardship. As part of the SHEQ leadership team, the role provides the enterprise with authoritative governance and oversight of the Sellafield Enterprise Management System (SEMS), ensuring arrangements remain robust, compliant and aligned with recognised good practice. The role underpins safe operations, hazard reduction and decommissioning by maintaining the integrity of the management system, embedding effective Quality standards, and enabling consistent, reliable and well‑controlled delivery across the Sellafield site and wider NDA estate.

The challenge for the role holder is to enable these high standards through:
• Strong leadership of teams to improve SHEQ performance;
• Coaching standards to improve behaviours and skills;
• Provision of SHEQ professional and expert services;
• Undertaking assurance and actions to address SHEQ performance gaps;
• Having rigorous oversight that holds Sellafield Ltd to account on SHEQ performance.

The 2025 government Task Force review of the nuclear industry and regulators provided recommendations focussed on accelerating delivery and reducing costs whilst maintain safety. This role is key in helping Sellafield Ltd:
• Simplify SHEQ processes and workflows for safe delivery;
• Reduce the culture of SHEQ risk aversion;
• Remove SHEQ cultural and capability approaches that unnecessarily block progress.

Success in this context requires deep collaboration and cooperation with peers in the SHEQ lead team, mission delivery, Project Directorate teams, regulators, industry partners and employee representatives. The role demands high levels of gravitas, integrity and professional credibility to represent Sellafield Ltd effectively at senior engagements with the NDA, government agencies and external stakeholders.
