About The Position

Amazon Leo is Amazon’s low Earth orbit satellite network, with a mission to deliver fast, reliable internet connectivity to customers beyond the reach of existing networks, including individual households, schools, hospitals, businesses, and government agencies. As a mechanical engineer within the propulsion team, you will be responsible for the end-to-end lifecycle of propulsion hardware, from initial concept through high-volume production and on-orbit operation. This role requires a combination of analytical rigor and hands-on build-and-test ownership to create lightweight, cost-effective hardware that performs consistently at scale. It is a collaborative, hands-on position that involves working across functional teams to develop the fluidic system and components that feed the thruster.

Requirements

• Bachelor's degree in mechanical engineering or equivalent
• Experience in the design of complex mechanical products and equipment at volume
• 7+ years of technical engineering experience
• Experience with qualification testing of space-grade hardware

Nice To Haves

• Advanced degree (Master’s or PhD) in aerospace or mechanical engineering, or related discipline
• Hands-on experience designing, building, and testing proportional flow control valves
• CAD software expertise (SolidWorks, NX, Creo, etc)
• Experience with tolerance analysis on precision assemblies
• Proficiency with Python or MATLAB for analysis & data visualization

Responsibilities

• Own the complete lifecycle of one or more propulsion subsystems from conceptual design through qualification, high-volume production, and on-orbit performance monitoring
• Solve complex mechanical and fluid system problems using first-principles analysis to drive design decisions and resolve ambiguity quickly
• Develop design criteria, collaborate on requirements, and lead system-level trade studies. Rapidly iterate on designs and analysis to inform high level trades and steer product development
• Design pressurized fluid components: isolation valves, flow control valves, restrictors, tubing, and manifolds, with full accountability for performance and life
• Perform and own fluid system analysis: pressure drop, flow transients, thermal soak, and leakage across the full operating envelope
• Produce complete design documentation - drawings, tolerance analyses, and test plans - at a level of detail that drives qualification & production without ambiguity
• Apply DFMA practices to minimize part counts and process steps while meeting high performance targets
• Plan and execute fluid system tests, performance characterization, and environmental qualification to validate analytical models and demonstrate compliance
• Lead root cause investigations for hardware failures and non-conformances; owning corrective action through closure
• Work cross-functionally with experts in plasma physics, avionics, thermal, structures, and materials as an accountable technical partner across the full product lifecycle

Benefits

• health insurance (medical, dental, vision, prescription, Basic Life & AD&D insurance and option for Supplemental life plans, EAP, Mental Health Support, Medical Advice Line, Flexible Spending Accounts, Adoption and Surrogacy Reimbursement coverage)
• 401(k) matching
• paid time off
• parental leave
