Senior Battery Systems Engineer
Job description
As a Senior Battery Engineer, you will drive the development of energy storage systems (ESSs) that power Anduril's next-generation drone products, from concept through full-rate production. Our battery packs enable everything from long-endurance loitering munitions to tactical unmanned aircraft operating in the most demanding environments. In this role, you will serve as the primary technical owner of ESS delivery, working on extremely accelerated timelines and acting as the main interface between the Core Battery Group and internal product teams. You will take individual ownership of battery packs from cell selection through pack prototype iterations to pack production.
