We are seeking a highly skilled Senior Systems Engineer to join our Aircraft Engineering Integration Team in Kemble. In this role, you will be responsible for the end-to-end integration of hydrogen-electric propulsion systems into aircraft platforms. You will work closely with multidisciplinary teams to ensure seamless system compatibility, safety, and certification readiness. This is a critical role in advancing ZeroAvia’s mission to deliver certified, zero-emission aircraft systems for commercial use. Responsibilities: Apply skills to deliver clear, structured, and communicated systems engineering documentation across aircraft, system, and item levels. Develop and maintain system simulation models, controls models, and manage their integration with the wider system engineering development. Work closely with Airworthiness, Certification, Systems Safety, System Test, and downstream engineering to deliver lean system development in line with the guidance of ARP4754A/B and ARP4761/A Continuously upgrade and update process and planning documentation based on iterative maturity development. Act as mentor across business functions on matters relating to lifecycle, development assurance, requirements management, and consistently demonstrate working-level best practice. Requirements Please only apply if you have experience in the aviation sector Demonstrated expertise in the application of Systems lifecycle processes (V-cycle), with a particular emphasis on the early phases of the V model. Previous experience within developmental lifecycles characterized by low maturity inputs is preferred. Proficient in aircraft control systems (preferably engine controls), including the capture of control functions and requirements, as well as the authoring of controller specifications to facilitate item development. Familiarity with aircraft or engine performance simulation and validation would be desirable. A proven track record of working effectively in small, high-performance teams is essential. Experience with certified or in-certification aircraft systems, including propeller, electrical power, flight control/avionics; or certified or in-certification powerplant systems, such as rotating components, engine control, and cooling/lubrication is considered advantageous. Extensive experience in the elicitation, capture, and management of requirement sets at all levels (aircraft, system, item), with a focus on ensuring their validation in accordance with completeness and correctness standards. Robust experience in the development of system architecture, functions, and interfaces, encompassing stakeholder management with downstream engineering teams, as well as assumption and risk management. Knowledge of system safety analysis techniques (FHA, FTA, FMEA) and reliability assessments is also desired. Considerable experience in managing systems engineering elements in software-centric environments, such as RMT (Polarion, DOORS) and CAE (Matlab Simulink, Simcenter). Strong aptitude for close collaboration with, and providing structure and clarity to, multiple cross-functional stakeholders. Additionally, a robust willingness to adapt based on stakeholder feedback and rigorous scrutiny is essential in this position. Experience in aviation-intended electric propulsion systems, fuel cell systems, or EVTOLs is considered a valuable asset. Essential Qualifications: Bachelor's degree in Aerospace, Mechanical, Electrical Engineering, or a related field; Master's degree preferred. Minimum of 7 years of experience in system safety engineering, particularly in the aerospace sector. Benefits Why Join Us?
