Hardware Reliability Engineer – Optical Inter‑Satellite Link (OISL)

About the role

Amazon Leo is building a next‑generation optical inter‑satellite link (OISL) for its low‑Earth‑orbit broadband constellation. The Reliability Engineer will develop and execute reliability strategies for complex opto‑mechanical, electrical, and electro‑optical hardware, ensuring products meet qualification and lifetime requirements in the LEO environment.

Key responsibilities

• Develop, implement, and maintain reliability models and frameworks for electrical, mechanical, and optical components and assemblies.
• Conduct failure mode and effects analysis (FMEA), fault tree analysis (FTA), and root cause analysis (RCA) for hardware systems and subsystems.
• Define and execute reliability demonstration testing (RDT), accelerated life testing (ALT), and highly accelerated life testing (HALT).
• Apply reliability growth models, Weibull analysis, and other statistical tools to predict and improve product lifetime.
• Establish reliability requirements and verification plans for new product development programs.
• Collaborate with design engineering to implement Design for Reliability (DfR) principles and conduct reliability risk assessments.
• Investigate field and test failures, drive corrective actions to closure, and maintain documentation such as test plans, reports, and specifications.

Required profile

• Bachelor’s degree in electrical, mechanical, material engineering or a related field.
• Industry experience applying reliability engineering principles to hardware.
• Proficiency with FMEA, FTA, RCA, and life‑testing methodologies.
• Strong statistical analysis skills, including Weibull modeling.
• Experience working cross‑functionally with design, systems, manufacturing, and test teams.
