EngineeringReliability Engineer

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.

Degree in Mechanical Engineering, Electrical Engineering, Chemical Engineering, Physics or
Equivalent.
