As a Senior Mechanical Engineer on the Avionics Mechanical team at Amazon Leo, you will be responsible for the mechanical design and development of spacecraft avionics hardware from concept through flight. This role requires collaboration across multiple engineering disciplines to ensure the robustness of electrical systems in space. You will lead engineering trade studies and develop innovative solutions to protect sensitive electronics while enabling efficient assembly and long-term mission success. The position offers significant technical ownership and the opportunity to mentor junior engineers.

• Bachelor's degree in mechanical engineering or equivalent
• 5+ years of hardware design and validation of components, subsystems, and systems experience
• Experience working in cross-functional teams with Electrical Engineering, Manufacturing, and Systems Engineering
• Experience using CAD tools to develop detailed mechanical designs and engineering documentation
• Strong understanding of Design for Manufacturing (DFM), Design for Assembly (DFA), and engineering best practices

• Own the mechanical design and development of spacecraft avionics hardware from concept through flight
• Partner with Electrical Engineering to develop robust packaging architectures for circuit boards, connectors, harnesses, and electronic assemblies
• Perform engineering trade studies balancing performance, reliability, manufacturability, mass, cost, and schedule
• Develop mechanical solutions that protect electronics from launch loads, vibration, thermal cycling, radiation, and the space environment
• Design qualification hardware, production fixtures, inspection tooling, and test equipment
• Collaborate across Mechanical, Electrical, Thermal, Reliability, Manufacturing, and Systems Engineering to retire technical risk early through analysis, prototyping, and testing
• Lead root cause investigations and implement design improvements throughout the product lifecycle
• Mentor junior engineers and help raise the technical bar across the organization
