Senior QA / Manufacturing Engineer

Fleetzero is a marine energy and robotics company focused on decarbonizing the global shipping industry through advanced battery technology and electric propulsion systems. Founded in 2021, the company develops the Leviathan Modular Energy Storage System, a marine battery platform engineered to deliver high energy density at costs competitive with fossil fuel alternatives. Their flagship marine battery container stores 3.8 MWh of energy in a footprint 25% the size of a standard shipping container, and the system is designed to scale from small support vessels to large ocean-going ships, including missions capable of crossing the Pacific Ocean on a single charge.

Build the processes, tooling, and quality infrastructure that takes Fleetzero hardware from bench builds to production-ready assembly lines.

ABOUT THE ROLE

You will own the intersection of quality and manufacturing engineering for battery module and BMS assembly. That means developing and qualifying assembly processes, writing work instructions and inspection criteria, and driving continuous improvement across the line. You will define what 'good' looks like for every assembly step — from incoming piece part inspection through end-of-line functional test.

This is a hands-on role. You will be on the floor developing tooling, troubleshooting process escapes, and running experiments alongside the assembly team. The right person has a bias for building systems that make quality repeatable and visible, and does not wait to be told what to inspect.
