Principal Product Engineer - BESS & DC Cabinets
On-siteHouston, Texas, United States
Job Summary
Set the architecture for BESS and DC Cabinet product lines and own the technical roadmap across multiple concurrent development cycles. Make hard trade-off calls on cost, reliability, and performance, then define engineering standards and review gates that the team adheres to. Personally own the hardest design pieces, including novel architectures, advanced component sizing, and complex protection schemes, while approving major design changes and acting as the final technical authority. Review and sign off on detailed engineering drawings at the production level, drive cycle cadence from concept through field deployment, and run strategic vendor relationships for key suppliers. Mentor engineers, lead design reviews and post-mortems, and represent the product team externally to customers, certifying bodies, and industry groups.
Required Qualifications
- Bachelor's degree in Electrical Engineering, Power Electronics, or a closely related technical field
- MS preferred
