About this role

Senior Test Engineer - Battery Systems Houston, TX Reports to: VP of Engineering Fleetzero is electrifying global maritime shipping with marine-grade lithium-iron-phosphate battery systems built for the harshest environments on the planet. Our Leviathan battery platform is in active ABS Product Design Assessment, with hardware on test rigs today and production hardware shipping in the near term. We are hiring a Senior Test Engineer to take full ownership of our battery test program: The rigs, the procedures, the automation, and the evidence packages that turn engineering work into class-approved, vessel-ready hardware. This is a hands-on role for an engineer who is equally comfortable wrenching on a fixture at 6 AM, debugging a CAN trace at noon, and presenting a thermal propagation test report to an ABS surveyor at 4 PM. You will own our hardware-in-the-loop (HIL) infrastructure, our cell/module/system-level test cells, and the requirements-to-evidence traceability that holds the whole program together. You will work shoulder-to-shoulder with our hardware, firmware, and systems teams to design tests early, fail hardware fast, and produce documentation that is self-explanatory to a first-time reader. If you have ever looked at a battery abuse test cell and thought "I could run this better," this is your job.
