Mechanical Engineer, Antenna Test Infrastructure

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. - Bachelor's degree or above in Mechanical Engineering
- 5+ years of experience in mechanical design of tooling, fixtures, and/or test equipment in a precision engineering or aerospace environment.
- Experience in 3D CAD (NX preferred) and PLM systems (Teamcenter preferred) for part modeling, complex assemblies, and drawing creation.
- Experience with GD&T (ASME Y14.5) and tolerance stackup analysis methods.
- Experience performing structural and/or thermal FEA to validate mechanical designs.
- Experience with CMM programming and operation, first-article inspection processes, and dimensional metrology.
- Experience with project-managing mechanical design efforts including budgeting, scheduling, and vendor coordination.
- Experience leading design reviews and mentoring junior mechanical engineers. - Master's degree in mechanical engineering or equivalent
- Experience designing mechanical systems for RF test chambers (anechoic, compact-range, or near-field) or antenna measurement facilities.
- Familiarity with the mechanical constraints imposed by RF environments — material selection for low reflectivity, EMI shielding, absorber mounting, and cable/connector routing.
- Experience with laser tracker operation, photogrammetry, or large-volume metrology for chamber and positioner alignment.
- Knowledge of thermal chamber mechanical design, including insulation, seal design, and thermal cycling considerations.
- Track record of managing large-scale capital equipment builds ($500K+) from concept through factory acceptance testing.
- Experience with Lean manufacturing principles and design-for-manufacturability in a production test environment.
- Proficiency in scripting or analysis tools (Python, MATLAB) for metrology data processing or parametric design studies.
