Previous experience in safety engineering for software-intensive, autonomous or AI-enabled systems is essential; experience across Land, Maritime, Air or Weapons, Ordnance, Munitions and Explosives (WOME) domains would be beneficial.

Your role

As an Autonomous Systems Safety Engineer, you will deliver safety engineering and safety assurance activities across complex autonomous, software-intensive and AI-enabled systems. Working with clients and multidisciplinary teams, you will provide authoritative safety advice, develop robust assurance arguments, and support the safe introduction of autonomy into Defence environments.

This role combines deep technical expertise with the ability to communicate clearly, influence decision-making and navigate complex stakeholder environments. You will help shape future approaches to autonomous systems safety while contributing to capability growth, technical leadership and mentoring across the team.

Your responsibilities may include:

• Leading and supporting the development, maintenance and delivery of Safety Cases, Safety Assessments and assurance arguments for autonomous and AI-enabled systems.
• Managing Hazard Logs and supporting hazard identification, risk assessment and risk management activities, including techniques such as FHA, STPA and Bow Tie Analysis.
• Deriving, allocating and verifying safety requirements throughout the lifecycle of complex autonomous, software-intensive and AI-enabled systems.
• Applying recognised defence safety standards and assurance frameworks, including Def Stan 00-056, Def Stan 00-055 and emerging autonomy and AI assurance approaches.
• Providing strategic and technical leadership as a Subject Matter Expert for autonomous systems safety across programmes and bids.
• Engaging with Defence customers, regulators, assurance bodies and industry working groups to support acceptance and certification.
• Providing safety engineering guidance to systems, software, hardware, integration and data specialist teams.
• Producing clear, robust and well-structured technical reports, safety documentation and client deliverables.
• Supporting business development, capability growth and the mentoring of more junior safety engineers and consultants.

About you

You are an experienced safety professional with strong expertise in software-intensive, autonomous or AI-enabled systems. You can apply sound engineering judgement, communicate clearly with technical and non-technical stakeholders, and work collaboratively across multidisciplinary teams.

Essential skills and experience

• Knowledge of UK Defence safety frameworks, including Def Stan 00-056, Def Stan 00-055 and associated assurance expectations.
• Experience supporting certification, assurance or acceptance of safety-critical systems.
• Experience applying or developing assurance approaches for autonomous or AI-enabled systems, including emerging frameworks such as AMLAS, SACE or equivalent.
• Ability to influence senior stakeholders, customers, regulators and assurance authorities through clear, evidence-based technical advice.
• Degree qualified, or equivalent experience, in Engineering, Mathematics, Physics, Computer Science or a related STEM discipline.

Desirable skills and experience

• Experience with advanced safety analysis techniques such as STPA, SOTIF, FMECA, FTA or equivalent methods.
• Experience developing assurance approaches for uncrewed, robotic or multi-agent autonomous systems.
• Experience applying simulation, modelling, virtual testing or scenario-based assurance for autonomous systems.
