As a member of our team, you’ll have the opportunity to work alongside a diverse group of highly skilled individuals, all driven by a shared passion for innovation and excellence. So, if you are passionate about space and ready to take your ambition to new heights, join us in our global mission to push the boundaries of what’s possible!

We are looking for a Space Systems Engineer to join our Product team within the Space Cloud business unit. The Space Cloud business unit develops, deploys and operates advanced in-orbit services aimed at delivering low latency intelligence for our customers. This is achieved via ground and space infrastructure, edge computing, sensors, connectivity and other solutions.

You will be responsible for the end‑to‑end engineering of space systems and missions, from requirements definition and architecture design through integration, verification, validation and in‑orbit support. You will work with multidisciplinary teams with a focus on the sub‑systems of avionics, flight software, ground software and telecommunications. You will also support technical interactions with suppliers and customers, contribute to major project reviews and provide engineering support to operations.

• Own system‑level design and technical coherence for selected missions and products (satellites, payloads).
• Derive, consolidate and manage system and subsystem requirements from customer needs, standards and mission objectives.
• Define and maintain system architectures, functional chains and interfaces (ICDs) between platform, payload and ground segment.
• Contribute to mission analysis and performance budgets (mass, power, data, thermal, link).
• Lead or support system‑level trade‑off studies (architecture options, technology choices, make‑or‑buy decisions).
• Prepare and maintain key systems engineering deliverables (CONOPS, requirement specifications, interface control documents, verification plans).
• Plan and support system integration, verification and validation activities at subsystem and system level (functional, performance, environmental and end‑to‑end tests).
• Contribute to anomaly investigation and in‑orbit troubleshooting.
• Coordinate technical data exchange with suppliers and partners, including review of their documentation and test results.
• Ensure compliance with relevant space standards (e.g. ECSS, CCSDS) and internal processes.
• Provide technical input for bids and proposals (system concepts, work breakdown, estimates, risks).

• Experience in systems engineering in space, aerospace or other highly regulated industries (e.g. defence, automotive, medical).
• Hands‑on experience with requirements engineering and configuration management tools (e.g. DOORS, Jama, Codebeamer).
• Proven experience in at least one of the following domains, plus a good understanding of the other: on‑board data handling and avionics; scientific/commercial payloads/instruments for EO; telecommunications; software development.
• Experience with performance budget preparation and analysis (e.g. mass, power, data, link or thermal budgets).
• Familiarity with space industry standards and practices (e.g. ECSS, CCSDS, NASA standards).
• Experience in system integration and testing, including reviewing test procedures, witnessing tests and analysing results.
• Comfortable working with simulation and modelling tools (e.g. MATLAB/Simulink, Python).
• Basic knowledge of common digital interfaces and buses used in space systems (e.g. CAN, SPI, I2C, Space Wire, MIL‑STD‑1553, Ethernet).
• Solid understanding of reliability, availability, maintainability and safety concepts (RAMS) is a plus.
• Strong analytical and problem‑solving skills with a structured, systems‑thinking mindset.
• A self‑starter with strong organisational skills; able to work effectively both independently and within…
