Senior Battery Engineer (Drones)

Requirements: Collaborate with program teams to translate user stories and CONOPs into actionable ESS requirements. Drive Cell Selection: Lead battery cell selection using accelerated de-risking and validation processes. Lead Design Iterations: Partner with mechanical engineers to deliver design revisions across component testing, mini (scaled down) modules, prototype packs, and production packs—defining the maturity required at each stage. Support Manufacturing Ramp: Work with manufacturing engineering to scale from prototype pack revisions to production units, ensuring adequate validation and reliability verification in an organized fashion through tools like DFMEAs. Get Hands-On: Directly support battery bring-up, test, debug, and vehicle integration activities. Sustain Fielded Systems: Conduct root cause analysis and data processing on fielded ESSs to drive countermeasures and design updates as needed.
