Senior Mechanical Engineer, Antenna Test & Automation, Leo Antenna Test Infrastructure
Amazon.comDESCRIPTION Amazon LEO is an initiative to increase global broadband access through a constellation of 3,236 satellites in low Earth orbit (LEO). Its mission is to bring fast, affordable broadband to unserved and underserved communities around the world. Amazon LEO will help close the digital divide by delivering fast, affordable broadband to a wide range of customers, including consumers, businesses, government agencies, and other organizations operating in places without reliable connectivity. The Antenna Test Infrastructure team develops the technology, systems, and chambers that validate LEO hardware across both Satellite and Customer Terminal programs. We design and build the mechanical infrastructure — test fixtures, handling tools, and RF chambers — that enable high-fidelity antenna characterization at production scale. In this role, you will serve as the senior mechanical engineering lead for tooling and chamber design within the team. You will own the full design lifecycle of test fixtures, assembly tooling, and RF chamber mechanical systems — from concept development and trade studies through detailed design, fabrication, and commissioning. You will drive GD&T rigor, lead design reviews, and ensure that every fixture and chamber meets demanding RF, thermal, and dimensional requirements. This is a hands-on technical leadership role: you will set the mechanical design standard for the team while project-managing complex builds across internal manufacturing partners and external vendors. Export Control Requirement 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. Key job responsibilities Lead the mechanical design of RF OTA test chambers, including structural enclosures, positioner mounts, DUT fixturing, cable routing, and access panel integration, ensuring designs meet RF performance, thermal stability, and dimensional accuracy requirements. Design and detail test fixtures, assembly tooling, and ergonomic handling aids for Satellite and Customer Terminal components and products across all stages of integration and test. Apply rigorous GD&T and perform tolerance stackup analyses to guarantee fit, function, and repeatability across multi-part fixture assemblies and chamber mechanical interfaces. Perform structural and thermal FEA to validate fixture and chamber designs prior to fabrication, iterating on geometry, material selection, and load paths to meet performance and safety margins. Create and release production-quality 2D drawings, 3D models, and BOMs in NX/Teamcenter; own document control processes and maintain configuration management for all tooling and chamber hardware. Lead part design reviews and peer reviews, establishing and enforcing mechanical design standards across the team. Develop and execute CMM inspection plans and first-article inspection (FAI) reports; operate or direct the operation of CMMs, laser trackers, and optical measurement systems to verify critical dimensions, alignments, and fixture repeatability. Define metrology strategies for chamber alignment verification, positioner accuracy characterization, and ongoing calibration of mechanical test infrastructure. Project-manage RF chamber design and build efforts end-to-end: scope definition, requirements capture, budgeting, scheduling, vendor selection, design review gates, and commissioning. Collaborate with RF, thermal, and systems engineering teams to translate test requirements into mechanical specifications and ensure chamber and fixture designs do not compromise electromagnetic or thermal performance. Coordinate with internal machine shops and external fabrication vendors on manufacturability, material procurement, and build schedules for custom capital equipment.
