You will lead system-level testing, create validation plans, and collaborate across disciplines to ensure performance, reliability, and safety of integrated battery systems.

Key Responsibilities
  • Participate in system-level testing of integrated battery systems for UPS, microgrid, EV charging, and data center applications.
  • Develop test plans and protocols to validate battery performance, life, and reliability at cell, module, and pack levels.
  • Conduct and document DFMEA and failure mode analysis for battery systems.
  • Define system-level requirements for size, performance, cost, and compliance for stationary battery systems.
  • Maintain technical documentation, including specifications, selection analysis, and simulation reports.
  • Collaborate with simulation, thermal, and mechanical engineers to define modeling requirements and validate battery architectures.
  • Partner with controls and software teams to establish guidelines for BMS design and integration.
  • Evaluate and benchmark new chemistries and competitive technologies to ensure best-in-class performance.
  • Support verification and validation activities by defining DVP&R for battery system testing.
  • Ensure compliance with industry standards (UL 9540A, UL 1973) and lead risk assessments for product safety.
Minimum Requirements
