Job summary

Lunar Energy is seeking a Senior Reliability Engineer specializing in power electronics to ensure product reliability across lifecycles of home energy products. You will collaborate with mechanical and electrical engineers during hardware design, provide DfR inputs, and drive DFMEA to capture risks and mitigations.

You will develop ALT reliability test plans, track field performance, and lead failure analyses to drive containment and corrective actions.

Qualifications

• Degree in Mechanical Engineering, Electrical Engineering, Chemical Engineering, Physics or Equivalent.
• Proven track record of solving complex power electronics reliability failures.
• Knowledge of power converter topologies (inverter, buck/boost).
• Knowledge of physics of failure and failure mechanisms for PCBAs and components.
• Experience with failure analysis techniques (optical microscopy, SEM, CSAM, X-ray, cross-sectioning, EDX).
• Experience with accelerated life testing models and governing equations for PCBAs and battery storage.

Responsibilities

• Collaborate with mechanical and electrical engineers during hardware design to establish reliability targets for power electronics and battery systems.
• Provide Design for Reliability (DfR) inputs during new product development.
• Drive DFMEA to capture performance risks and mitigation activities.
• Develop ALT Reliability Test Plans for components and subsystems.
• Track field reliability performance and warranty program insights.
• Lead failure analyses to determine root cause and drive corrective actions.
