Senior Safety & Risk Consultant

Assystem is an international company with one mission: accelerate the energy transition around the world.

Every day, our 8,000+ switchers located in 14 countries (Europe, Middle East, Pacific Asia & Africa) connect their six thousand billion neurons to tackle the task of the century: switching to low-carbon energy. We are a collective committed to making the energy switch. Sharing our knowledge, expertise and values allows us to innovate and think differently about the energy transition.

Here is how you can be a part of that switch:

Assystem’s Safety & Risk business supports some of the UK’s most complex infrastructure programmes across nuclear, defence and critical national infrastructure.

We provide independent technical authority combining engineering insight, regulatory understanding and delivery pragmatism to ensure safety is demonstrably achieved and maintained across the full lifecycle.

We are expanding our support across major infrastructure programmes and are seeking a Safety Case Manager to lead and assure safety activities within complex, highly regulated environments.

You will operate as a technical authority and Intelligent Customer, setting expectations, assuring technical quality, and influencing key safety decisions across the full project lifecycle. The role requires strong technical judgement, the ability to challenge constructively, and confidence working across multidisciplinary teams.

This is an opportunity to work at the forefront of high-consequence engineering, where safety is critical to successful delivery and where your input will directly shape how complex infrastructure is designed, justified and brought into operation.

Safety Case Leadership & Assurance

• Lead development and integration of Safety Cases across design, construction and operational phases
• Assure the strength of safety arguments, evidence and hazard management approaches
• Provide oversight of safety strategies and justification plans

Intelligent Customer Function

• Challenge design and safety assumptions to ensure proportionate, compliant outcomes
• Assure supply chain outputs meet technical and regulatory expectations

Stakeholder & Programme Engagement

• Interface with stakeholders, delivery partners and regulators
• Provide clear, authoritative advice in complex programme environments

We’re looking for a Safety Case professional who is comfortable operating as a trusted technical authority within complex, highly regulated defence or nuclear environments. You will bring a strong track record in Safety Case development and assurance, with the confidence to challenge assumptions, interrogate evidence, and guide multidisciplinary teams toward robust, defensible safety outcomes.

You are likely already operating at Senior or Principal level, whether as a Safety Case Manager, Principal/Senior Engineer or within an Intelligent Customer role, and understand how to balance technical rigour with the realities of programme delivery. Experience working within UK regulatory frameworks such as ONR or DNSR is important, but equally critical is your ability to navigate ambiguity, influence senior stakeholders, and apply sound judgement where there is no single “right” answer.

Above all, you take ownership of safety outcomes, hold high standards for technical quality, and are motivated by the responsibility that comes with working on complex, high-consequence infrastructure.
