Principal System Safety Engineer

SC Clearance is essential (SC)

Up to £76 p/h Inside IR35

Southampton HQ - 1-2 days a week onsite

We are seeking an experienced security cleared Principal System Safety Engineer to support the development of advanced technologies. This role focuses on the integration of complex sensing, communications systems by bringing together multiple interconnected subsystems within a wider aircraft architecture.

This is an exciting opportunity to take a leading role in system safety across a highly complex, safety-critical aerospace engineering environment. You will work closely with multidisciplinary teams to ensure system-level hazards, risks and dependencies are identified, assessed and effectively managed throughout the engineering life cycle.

The role would suit a safety professional who can understand complex system interactions, work confidently across engineering disciplines and lead the delivery of integrated safety assessments.

Key Responsibilities

• Provide specialist safety advice to the relevant Safety and Design Authority, supporting product safety authorisation in accordance with established processes.
• Lead system safety activities, ensuring compliance with the agreed Safety Management Plan.
• Identify and analyse intrinsic and functional hazards, developing appropriate mitigations to reduce residual safety risks to ALARP.
• Develop and manage system safety requirements, ensuring they are appropriately allocated and flowed down to relevant subsystems and engineering teams.
• Review subsystem-level safety analyses and integrate their findings into the overall system safety assessment.
• Review aircraft-level safety analyses, ensuring consistency and alignment with the wider system safety assessment.
• Produce and maintain integrated system safety documentation and assessments in line with programme requirements.
• Identify and manage cross-system dependencies, interfaces and safety implications across the wider aircraft architecture.
• Present safety assessment findings at programme design reviews, clearly communicating safety status, risks and mitigation strategies.

Essential Experience and Skills

• *Security cleared currently*
• Proven experience conducting safety analysis of complex systems within a safety-critical industry.
• Experience working across multiple engineering life cycle phases, from design and development through to verification and validation.
• Demonstrable experience leading and delivering safety work packages involving multiple teams.
• Excellent written and verbal communication skills, including presenting technical safety assessments to stakeholders at varying levels of seniority.
• Experience with aerospace safety and assurance standards such as ARP4754B, ARP4761A, RTCA DO-254 or DO-178C would be advantageous.
• Experience working with complex system designs involving significant uncertainty and technical challenges.
• Knowledge of radar, Laser technologies, sensors or Defensive Aids Systems (DAS).
• Awareness of information security principles within complex engineering programmes.
• Involvement in cross-industry safety initiatives, such as those associated with the Institution of Engineering and Technology (IET) or the Safety-Critical Systems Club (SCSC).

Tools and Technologies

Experience with any of the following tools would be an advantage:

• Cameo Systems Modeler
• IBM DOORS
