Senior Space & Radiation Effects Engineer, Amazon Leo

Mentions AI-vibe coding as a preferred skill alongside Python and Lab View, suggesting occasional use of AI-assisted tooling or scripting for analysis and automation.

Senior Radiation Effects Engineer for Amazon Leo responsible for ensuring avionics and payload hardware reliability across a LEO satellite constellation by performing radiation analysis, component qualification, testing, and failure investigations to maintain on-orbit performance.

As a Senior Radiation Effects Engineer on the Amazon Leo team you will ensure avionics and payload hardware performance across a low Earth orbit satellite constellation by performing radiation analysis, defining test methods, qualifying components, and investigating on-orbit radiation events.

• Define, collect, and analyze TID, heavy ion, and proton test data to qualify components and build a component test database.
• Determine system-level impacts of radiation-induced failures and lead root-cause analysis for on-orbit radiation events.
• Qualify electronic components including microcontrollers, memory devices, FPGAs, and power management hardware.
• Provide guidance to electrical design engineers on selection and use of radiation-sensitive components.
• Develop processes, testing standards, and documentation practices for component and flight PCBA radiation tests.
• Develop tools and dashboards to organize and visualize on-orbit events and test results.
• Work with supply chain and component reliability teams and review PCN changes to maintain radiation qualification status.

• Bachelor’s degree in Electrical Engineering or related field, or equivalent experience in electrical engineering.
• 3+ years of experience in spaceflight avionics development, parts selection, and radiation testing.
• 3+ years of system design and component qualification experience with radiation environments and radiation-tolerant hardware.
• Demonstrated understanding of single-event effects (SEE) and total ionizing dose (TID) impacts on electronic systems.
• Experience with one or more radiation environment modeling tools such as IRENE, OMERE, SIRE2, SPENVIS, OLTARIS, CREME
  96, SAPPHIRE, ESP, or PSYCHIC.

• Advanced degree (Master’s or PhD) in Electrical Engineering, Computer Science, Mathematics, or Physics.
• Experience with radiation transport codes (e.g., NOVICE, FASTRAD, SHIELDOSE2, GEANT4, MCNP).
• Experience with NASA, defense, or commercial space programs and vehicle-level reliability models.
• Experience with component selection, reliability assessment, and hardware troubleshooting (PCBA, ICs, sensors).
• Familiarity with Python, Lab View, or AI-vibe coding, and AWS tools such as S3 and DynamoDB.
