Space Mechanisms Engineer H/F

Description

Les missions du poste About the Company Established in 2017, Infinite Orbits is a NewSpace company, based in Toulouse, pushing the boundaries of in-orbit services with cutting-edge spacecraft driven by its own Rendez-Vous solution, an advanced Autonomous Vision-Based Navigation Solution. IO has two generations of missions "Orbit Guard" provides Inspection and Space Situational Awareness services in GEO. Our first, OG-1 was launched on 1 May 2023, the second is launching in 2025 and the third third launching in 2026. "Endurance" is a docking service capable of extending the life of GEO telecom satellites, by taking over AOCS takeover for 5 years. You will lead the design, development, and qualification of space mechanisms across all IO missions, with a focus on robotic arms and thruster actuation systems. This is a high-ownership role where you are responsible for ensuring that mechanisms not only work on paper but also survive launch, perform flawlessly in orbit, and continue to do so over the mission lifetime. In a small space robotics company, your designs won't linger in CAD. They will be built, tested, challenged, and ultimately sent into space under your responsibility. Key Responsibilities Technical Ownership - Own the full lifecycle of critical mechanisms across IO missions. - Design and deliver: - Robotic arm joints, end-effectors, and deployment systems. - Thruster gimbals, valves, and actuation systems. - Ensure all actuator elements (launch locks, motors, gearboxes, lubricants) are correctly sized, selected, and qualified according to mission requirements. - Define mechanism architectures and actuation strategies (electric, spring-driven, hold-down & release, etc.). Design, Analysis & Verification - Perform and lead detailed mechanical design activities: - CAD, tolerance stack-ups, and precision alignment strategies. - Carry out comprehensive analysis and verification campaigns, including: - Structural, thermal, and dynamic analyses. - Launch loads (vibra
