Sr. Mechanical Engineer, Electronics Packaging, Avionics Mechanical

Amazon Leo is Amazon's low Earth orbit satellite network. Our mission is to deliver fast, reliable internet connectivity to customers beyond the reach of existing networks. From individual households to schools, hospitals, businesses, and government agencies, Amazon Leo will serve people and organizations operating in locations without reliable broadband access.

About the role

As a Senior Mechanical Engineer on the Avionics Mechanical team, you will own the mechanical implementation of spacecraft electrical systems from early architecture through flight hardware. You will work at the intersection of mechanical, electrical, thermal, reliability, and manufacturing engineering to develop innovative solutions that protect sensitive electronics while enabling efficient assembly, qualification, production, and long-term mission success. This is a highly cross-functional role with significant technical ownership, requiring sound engineering tradeoffs across multiple disciplines to balance performance, reliability, manufacturability, cost, and schedule.

Responsibilities

• 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.

A day in the life

As a Senior Mechanical Engineer, you'll work across nearly every engineering discipline involved in spacecraft development. One day you may be developing a new avionics packaging architecture alongside electrical and thermal engineers. The next, you could be reviewing vibration or thermal vacuum test results, troubleshooting qualification issues with manufacturing teams, or leading a design review for flight hardware entering production. You'll regularly perform engineering trade studies, evaluate failure modes, work directly with suppliers, support qualification testing, and develop innovative solutions that improve reliability, manufacturability, and system performance.

About the team

The Avionics Mechanical team partners closely with Electrical Engineering to ensure every spacecraft electrical subsystem is mechanically robust throughout manufacturing, launch, and mission life. The team is responsible for the structural implementation of avionics hardware, including enclosure design, packaging architecture, mounting strategies, and environmental protection. Engineers solve challenging problems involving PCB support, connector retention, thermal interfaces, fastener design, electronics packaging, and long-term material durability while balancing system performance with manufacturability. The team also develops specialized qualification hardware, manufacturing fixtures, inspection tooling, and test equipment that enable efficient verification throughout the product lifecycle.

Requirements

• Experience in developing functional specifications, design verification plans, and functional test procedures.
• 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.
• Experience conducting engineering trade studies and making data-driven technical decisions.
• Strong understanding of Design for Manufacturing (DFM), Design for Assembly (DFA), and engineering best practices.

Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

Preferred Qualifications

• Master's degree in electrical engineering, computer engineering, or equivalent.
• Experience working with interdisciplinary teams to execute product design from concept to production.
• Experience with the project management of technical projects.
• Experience developing aerospace, satellite, defense, medical device, automotive, semiconductor, or consumer electronics products.
• Experience designing electronics packaging, structural enclosures, or electromechanical assemblies.
• Experience with environmental qualification testing, including vibration, shock, thermal cycling, thermal vacuum, or accelerated life testing.
• Experience with engineering tools and methodologies such as FMEA, tolerance analysis, root cause analysis, and Design Verification & Validation (V&V).
• Familiarity with thermal interface materials, adhesives, conformal coatings, EMI mitigation, or other materials used in high-reliability electronic systems.
• Demonstrated ability to lead technical efforts across multiple engineering disciplines and mentor junior engineers.
• Excellent written and verbal communication skills with the ability to influence technical decisions across cross-functional teams.
