As a Satellite Systems Designer/Engineer
, you will be contributing across multiple programs, helping to deliver critical subsystems and work packages that roll up into larger missions. You’ll draw on your experience across different lifecycle phases, from requirements definition, design, integration, verification, or operations, to quickly integrate into new projects and technical deliverables.

You will act as a bridge between disciplines, ensuring requirements are met, interfaces are well managed, and risks are identified and mitigated. Success in this role comes from your ability to transition smoothly between projects, “right‑size” processes to the maturity of the work, and keep teams aligned on delivery. This role demands deep expertise in systems engineering and a strong ability to mentor junior engineers while delivering high‑impact technical solutions.

• Define system architectures and system‑level engineering for spacecraft, subsystems, or work packages, spanning both space and ground segments.
• Translate customer and program requirements into clear technical deliverables; develop and manage requirements, interface control, and verification strategies.
• Perform system modeling, mission analysis, trade studies, risk assessments, and performance analysis to inform design decisions.
• Drive subsystem integration and interface management across hardware, software, avionics, RF, payload, or ground systems.
• Apply reliability and risk practices such as RAMS, FMECA, and FDIR analysis where relevant.
• Contribute to LEOP, commissioning, and on‑orbit operations planning and support as required.
• Support bids and proposals by preparing technical inputs, feasibility assessments, and documentation.
• Integration, test campaigns, and mission readiness activities.
• Provide technical oversight and mentorship to junior and intermediate engineers.
• Serve as a strong technical interface for customers and external stakeholders.
• Ensure compliance with industry standards and best practices.

• Bachelor’s or Master’s degree in Systems Engineering, Aerospace Engineering, Electrical Engineering, or a related field.
• 4+ years of experience in systems engineering, spacecraft development, or similar technical leadership roles.
• Proven track record delivering subsystems, technical work packages, or verification campaigns within larger missions.
• Experience with mission analysis, system modeling, technical budget…
