About the role

  • You should have lived through full product development cycles and know how to bring engineering discipline into a fast-moving environment with frequent release cycles.

Responsibilities

  • Author and maintain detailed technical specifications for the BESS and DC Cabinet - electrical, mechanical, environmental, and interface requirements.
  • Review and approve detailed engineering drawings: SLDs, GAs, schematics, wiring diagrams, panel layouts, mechanical drawings, and BoMs. Own the technical change baseline.
  • Perform in-depth component sizing: fuses, busbars, cables, contactors, disconnects, protection coordination, short-circuit and arc-flash inputs, and thermal sizing of cabinets (forced air / HVAC, natural convection, hot-spot analysis, derating).
  • Lead technical engagement with key vendors - particularly on the DC Cabinet - driving specs into RFQs, evaluating vendor designs, running design reviews, and resolving issues through prototyping, FAT, and serial production.
  • Qualify alternate suppliers and own the technical side of dual-sourcing and cost-down decisions.
  • Drive iterative product development cycles with the development team, balancing speed with the rigor expected of mission-critical hardware.
  • Capture design feedback from design reviews, commissioning, and O&M, and convert it into prioritized changes on the product roadmap via a structured ECR/ECN process.
  • Run trade studies on architecture and component selection where it matters - cost, reliability, lead time, performance.
  • Project & Commercial Support
  • Support business development with technical proposals - SLDs, GAs, and SOC analysis across multiple market applications.

Requirements

  • Bachelor's degree in Electrical Engineering, Power Electronics, or a closely related technical field.
  • 6+ years of hands-on engineering experience in BESS, power electronics, UPS, or comparable mission-critical / industrial power systems, with clear evidence of ownership through full product development cycles.
  • Demonstrated experience taking a product through the full development cycle - concept, prototype, FAT, field deployment, revision - in an environment with frequent release cycles.

Nice to have

  • Fluency producing and reviewing SLDs, GAs, schematics, and panel layouts
  • comfortable in AutoCAD or equivalent E-CAD tools and reading mechanical drawings.
  • Willing to travel up to 20%.
  • Experience with data center / UPS / mission-critical power or utility-scale BESS.
  • Familiarity with UL 9540 / 9540A and NFPA 855, plus the relevant codes for your target market.
  • Experience with PLM tools and structured ECR/ECN workflows.
