Avionics System Engineer

Who we’re looking for

• Relevant education Degree in Aerospace Engineering, Electrical Engineering, or a related technical field
• Professional and methodical competence Proven experience in spacecraft avionics systems or complex embedded/electrical systems engineering
• Strong knowledge of spacecraft subsystems (AOCS, data handling, TT&C, power, communications)
• Experience with system engineering processes (requirements management, verification, architecture, FDIR)
• Ability to effectively manage and challenge suppliers and subcontractors, ensuring delivery, quality, and timely issue resolution
• Strong communication and coordination skills in multidisciplinary environments
• Personal and Social Competencies Strong communication and teamwork skills combined with decision-making ability and assertiveness. Structured and analytical working style with a proactive, solution-oriented mindset.
• Ability to work independently with a high level of ownership, flexibility, and reliability. Demonstrates integrity and maintains a confident, professional approach.

What you’ll do

• The Avionics System Engineer ensures the coherent design, development, integration, and performance of the spacecraft avionics system, including all related subsystems.
• The role acts as the primary technical interface to the avionics subcontractor and works in close cooperation with the Subcontract Manager.
• The engineer is responsible for the definition, development, and control of the avionics architecture (platform and flight), including full lifecycle ownership of system and subsystem requirements. This includes requirement definition, flow-down, maintenance, and bidirectional traceability, ensuring alignment with overall spacecraft system needs and performance objectives.
• The key aspect of this role is strong and proactive supplier oversight — ensuring compliance with technical, quality, schedule, and performance requirements through structured follow-up, clear expectation setting, and timely escalation when needed.
• The role oversees and steers the development, integration, and verification of key avionics subsystems: AOCS, Data Handling and Payload Data Handling, Telemetry, Tracking & Command (TT&C), Data Downlink, and Communications, Power subsystem (including system-level power analysis, solar generator sizing, and accommodation), Harness subsystem (including routing optimization and modularity in cooperation with the MTP System Engineer).
• The Avionics System Engineer ensures proper interface definition and coordination between avionics, platform, and MTP accommodation requirements. The role controls platform architecture consistency and component maturity (TRL), and ensures compliance with system-level constraints.
• Additional responsibilities include coordination of EMC and radiation engineering activities, technical coordination of avionics subcontractor AIT activities (including EFM, PFM, SCOE, and Suitcase models), and support to overall spacecraft integration and verification.
• The role contributes to FDIR definition within its scope and is responsible for reviewing and approving relevant technical documentation. It also involves making or escalating technical decisions, proposing solutions to identified issues, and ensuring proper reporting of impacts.
• The Avionics System Engineer performs technical coordination of assigned resources and ensures high-quality, consistent, and timely delivery of avionics solutions. The role is supported by the Electrical Design Expert.
