Descripción de la oferta
Sateliot is a Barcelona-based Startup in the New Space sector, becoming the first satellite telecommunications operator that will provide global and continuous connectivity to all the elements that will make up the massive Internet of Things (IoT) universe under the 5G protocol . Sateliot is the perfect complement for large telecommunications companies by providing them with the necessary infrastructure where terrestrial technologies do not arrive. Sateliot is seeking a Principal Mechanical Engineer to lead mechanical and thermal-structural engineering across the full lifecycle of an advanced LEO satellite platform and payload antenna system. This role requires a deep first-principles approach to mechanical design, combined with hands-on expertise in developing lightweight, deployable, semi-rigid space structures that must survive launch loads, deploy reliably in orbit, and maintain performance through aggressive LEO thermal cycling. The successful candidate will take ownership from early concept and detailed design through manufacturing, qualification, integration, testing, and on-orbit support. Own the mechanical design of the satellite bus structure and payload antenna assemblies. Design and qualify deployable mechanisms and semi-rigid lightweight structures (antenna deployment systems, panels, booms, hinges). Ensure robust repeatability, stiffness, and dimensional stability after deployment. Address latch design, hold-down release mechanisms, tolerances, and deployment dynamics in orbit. High-frequency thermal cycling (eclipse transitions)Thermo-elastic distortion affecting payload pointing and RF performance Define qualification and acceptance approaches suitable for LEO constellation-style deployment, balancing reliability and production cadence. Full Engineering Lifecycle Ownership Detailed CAD and manufacturing release Supplier engagement and production readiness Assembly, Integration & Test (AIT)Qualification campaigns (vibration, thermal vacuum, deployment testing)Structural Analysis & Verification Oversee structural analysis activities, including: Modal analysis, static margins, buckling, dynamic response Support hardware test execution, anomaly resolution, and design iteration. Act as mechanical technical authority interfacing with systems, RF, thermal, avionics, manufacturing, and mission teams. Mentor engineers and elevate structural/mechanical rigor across the organization. General ~ MSc or PhD in Mechanical Engineering, Aerospace Engineering, or related discipline. ~10+ years of experience delivering flight mechanical hardware for spacecraft or high-reliability aerospace systems. ~ Experience with qualification documentation, test correlation, and margin tracking End-to-end ownership mindset across design → test → flight Strong balance of analytical depth and practical build/test execution Comfortable working in fast-paced, high-performance LEO development environments Precision machining and additive manufacturing where appropriate Experience supporting cleanroom integration and test campaigns.
