System Safety Engineer

Overview

Expleo is a trusted partner for end-to-end, integrated engineering, quality services and management consulting for digital transformation. We help businesses harness unrelenting technological change to successfully deliver innovations that will help them gain a competitive advantage and improve the everyday lives of people around the globe.

As part of our continued growth in test equipment design and development,we are seeking a System Safety Engineer to support the development and certification of next-generation electric rotorcraft (eVTOL) platforms, with a particular focus on powertrain, battery systems, and high-voltage electrical architectures.

This role is central to ensuring that safety considerations are embedded throughout the engineering lifecycle, from requirements definition through to certification. You will lead and contribute to safety analyses that demonstrate compliance with stringent aviation safety standards, ensuring that innovative electric propulsion systems achieve the required levels of safety and reliability.

This is an opportunity to work on cutting-edge aerospace technology, shaping the safety case for future sustainable aviation solutions.

This role is Hybrid working in Bristol.

Within this role, you will be required to :

-

• Perform system safety assessments for powertrain, battery, and electrical systems across the development lifecycle

• Conduct key safety analyses, including FHA, PSSA, SSA, FTA, and FMEA, to identify hazards and define mitigation strategies

• Develop and maintain hazard logs, ensuring hazards are tracked, mitigated, and closed appropriately

• Define safety requirements and safety objectives, ensuring alignment with system design and certification expectations

• Support the development of safety architectures, including redundancy, independence, and fault tolerance principles.

• Contribute to the creation and maintenance of the system safety case, ensuring robust justification of compliance.

• Collaborate with systems, design, test, and certification teams to ensure safety is fully integrated into engineering activities
• Support verification and validation activities, ensuring safety requirements are testable and verified
• Perform analysis of failure conditions (e.g. loss of thrust, electrical faults, battery hazards) and their impact on aircraft-level safety
• Support certification processes, including preparation of safety documentation for regulatory authorities
• Participate in design reviews and safety boards, providing expert input and challenge where necessary
• Identify and manage technical safety risks, ensuring appropriate mitigation strategies are implemented

• Bachelor’s or Master’s degree in Aerospace Engineering, Mechanical Engineering, or related field.
• Chartered engineer or working towards chartered status within a recognised and relevant professional body.
• Applications are invited from candidates who may hold HNC/HND in a relevant engineering discipline in concert with significant and demonstrable subject matter expertise in the system domain

• Strong experience in system safety analysis, including FHA, FMEA, FTA, and SSA

• Understanding of hazard identification, risk assessment, and mitigation strategies

• Experience developing and managing safety cases and hazard logs

• Knowledge of system architectures and safety design principles (redundancy, segregation, fault tolerance)

• Ability to assess failure conditions and their impact at aircraft level

• Strong analytical and problem-solving capability

• Excellent communication skills and ability to work across multidisciplinary teams

• Ability to produce clear, structured safety documentation

• Experience in electric propulsion systems, battery technologies, and high-voltage systems safety

• Familiarity with EASA CS-23, CS-27, or CS-29 certification environments

  Knowledge of functional safety standards (e.g. IEC 61508 or similar)

• Experience with Common Cause Analysis (CCA), Zonal Safety Analysis (ZSA), or Particular Risk Analysis

• Experience supporting certification programmes or regulatory interactions

  Exposure to Advanced Air Mobility (AAM), eVTOL, or emerging aviation platforms

• Familiar it…
