Job summary

Staff Reliability Engineer with Lunar Energy, Inc. will focus on ensuring product reliability across lifecycle of home energy products. You will collaborate with mechanical, electrical, and battery teams, contribute DFMEA, and develop ALT reliability plans to meet targets.

Based in California, the role offers a competitive salary and equity; a strong focus on design-for-reliability and field performance is expected.

Qualifications

• Degree in Mechanical Engineering, Electrical Engineering, Chemical Engineering, Physics or Equivalent.
• Proven track record of solving complex power electronics reliability failures
• Working knowledge in theory of operation of common power converter topologies (inverter, buck boost converter…etc)
• Strong grasp of PCBA-level failure physics (CTE mismatch, solder fatigue, contact resistance, insulation degradation)
• Familiarity with failure modes in common power electronics components (electrolytic caps, relays, semiconductors, magnetics)
• Working knowledge of failure analysis techniques such as optical microscopy, SEM, CSAM, X-ray, cross-sectioning and EDX - know which technique to recommend given a specific failure
• Experience with accelerated life testing models and the governing equations, specifically for PCBAs, battery storage, and relevant mechanical structures.
• Understanding of reliability statistics

Responsibilities

• Collaborate with mechanical and electrical engineers during hardware design to establish and refine component and system level reliability targets for our power electronics and battery systems.
• Provide Design for Reliability (DfR) inputs during new product development.
• Drive Design Failure Modes and Effects Analyses (DFMEA) for various systems to capture performance risks and implement appropriate mitigation activities.
• Develop ALT Reliability Test Plans for components and subsystems using identified risks, reliability targets, and physics of failures methodology to demonstrate the required product reliability throughout its design life.
• Track field reliability performance for various metrics like part replacements, customer complaints, fault codes. Identify opportunities for continuous product improvement and reliability growth. Collaborate with the finance team to provide insights into our warranty program.
• Drive failure analysis of reliability test and/or field returns to determine root cause and drive product improvement through containment and corrective actions.
