  • Own complex integration strategies across electrical, mechanical, controls, communications, and cloud interfaces.
  • Define verification and validation (V&V) strategies. Collaborate with lab and field engineering teams to oversee hardware testing, prototype validation, FAT/SAT protocols, and full qualification
  • Support, lead, and facilitate Root Cause Analysis (RCA), Management of Change, and incorporate field feedback into future designs
  • Lead product safety engineering activities, including DFMEA, FMEA, HARA, and Fault Tree Analysis (FTA)
  • Ensure product compliance with global standards, codes, and regulatory requirements (e.g., UL 9540, UL 9540A, IEC 62933, NFPA 855, NFPA 70, IEEE, etc).

  • Extensive experience with utility-scale Battery Energy Storage Systems (BESS), Power Conversion Systems (PCS), microgrids, or grid integration
  • Deep understanding of systems engineering principles, including requirements development, functional decomposition, interface management, system architecture, and verification & validation.
  • Strong technical background spanning electrical, mechanical, controls, embedded, and software systems.
  • Proven track record of conducting safety and risk assessments (DFMEA, FMEA, HARA) and root cause analysis.
