LEO Satellite Propulsion Systems Engineer

Amazon; Redmond (WA); On-site; USD 136,000 - 184,000; Full time

Job summary

Amazon Leo in Redmond, WA, is seeking a Systems Engineer to own the propulsion subsystem requirements and interfaces for our electric propulsion hardware aboard ultra-high‑velocity satellites. The role blends 70% systems engineering and 30% hardware development, with responsibilities spanning budgets, verification, and cross‑functional collaboration across flight software, GNC, power, avionics, and tests.

You will work hands-on with thrusters, power processing units, and feed systems, build the

Qualifications

• Bachelor's degree in Mechanical, Aerospace, or Manufacturing Engineering or equivalent.
• 3+ years of technical engineering experience.
• Experience developing, analyzing, or testing spacecraft or propulsion hardware.
• Experience developing functional specifications, requirements, and interface definitions, plus V&V plans.
• Experience with physics-based modeling and analysis of propulsion or spacecraft systems.
• Proficiency with scripting (Python, MATLAB) for analysis and data visualization.

Responsibilities

• Derive and maintain propulsion subsystem requirements from mission, spacecraft, and regulatory needs.
• Maintain propulsion baseline and change control across designs.
• Own propulsion budgets and margins and assess impact of changes at constellation scale.
• Define and maintain interfaces between propulsion and flight software, GNC, power, avionics, thermal, and structures.
• Deliver analyses and trade studies for propulsion architectures and drive decisions.
• Define test requirements and verification traceability; partner on hardware-in-the-loop and qualification campaigns.
• Contribute to FMECA, fault management, and risk assessments with mitigations.
• Prepare and present material for design reviews and readiness reviews with suppliers.
• Build hands-on propulsion expertise through test support, data analysis, and troubleshooting.
• Support propulsion CONOPS and in-flight response procedures for off-nominal scenarios.
• Track propulsion system performance using on-orbit and production data; support root-cause investigations.
• Work cross-functionally with plasma physics, mechanical design, avionics, flight software, flight dynamics, and test.
