About the Role We're looking for a highly skilled Senior Mission Systems Engineer to join a team developing advanced onboard computing solutions for a cutting-edge aerospace programme. You will work on secure, resilient systems, contributing to designs that directly impact critical mission systems. You'll collaborate with a multi-disciplinary engineering team, helping to define system architectures, integrate hardware and software solutions, and ensure designs meet technical, operational, safety, and security requirements. Key Responsibilities Support system-level design and architecture for onboard computing solutions. Collaborate across internal and external teams, including international partners, to ensure designs are robust and aligned with programme objectives. Develop, simulate, and verify digital logic using VHDL as a core part of system modeling and design. Provide mentorship and guidance to less experienced team members. Apply systems engineering principles to support safety, security, and regulatory compliance in complex aerospace or mission-critical systems. Represent the team in meetings with stakeholders, contributing to effective collaboration and problem-solving. Required Skills and Experience Degree (or equivalent) in a STEM discipline. Proven experience in Systems Engineering and the engineering lifecycle, ideally in aerospace, avionics, or complex computing systems. Strong VHDL experience is essen...
