MechanicalHarnessEngineer

AST SpaceMobile is building the first and only global cellular broadband network in space to operate directly with standard, unmodified mobile devices based on our extensive IP and patent portfolio and designed for both commercial and government applications. Our engineers and space scientists are on a mission to eliminate the connectivity gaps faced by today’s five billion mobile subscribers and finally bring broadband to the billions who remain unconnected. Position Overview We are seeking a highly skilled and detail-oriented Mechanical Harness Engineer to join our dynamic team working on state-of-the-art Low Earth Orbit (LEO) satellite systems. In this role, you will design, develop, and integrate electrical harnesses that form the backbone of the satellite’s electrical system, ensuring reliable and efficient power and data transfer for successful missions. Key Responsibilities Design and develop electrical harnesses for LEO satellite systems, considering mission requirements, space constraints, thermal considerations, and EMC requirements. Collaborate with system engineers, electrical designers, and mechanical engineers to define harness specifications and design constraints. Create and manage detailed harness drawings, including cable/wire routing, connector selection, splicing, and termination plans using CAD tools. Ensure compliance with industry standards (e.g., IPC-WHMA-A-620, ECSS-E-HB-10-10) and space agency requirements. Conduct analyses and simulations to verify mechanical integrity, electrical performance, and environmental resistance. Support fabrication, assembly, and testing of harnesses, providing guidance to ensure quality and adherence to specifications. Perform in-house testing and validation, including continuity checks, insulation resistance, and signal integrity testing. Collaborate with suppliers to source space-qualified components while maintaining cost-effectiveness and schedule adherence. Document all design and testing activities, inclu
