Job description

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.

How we work

We are a small, dense engineering team in Houston. We test early, test often, and break hardware on purpose. We work in person because integration problems live in the gaps between disciplines, and the gaps close faster when you can walk over to the next bench. We document because the next person who reads our work might be a class surveyor, a customer's chief engineer, or a future version of ourselves at 2 AM in a shipyard.

Our team includes mariners, fabricators, software engineers, sales people. We respect the trades and the textbooks equally.
