Overview As a Senior Mechanical Design Engineer at Anduril, you will own end-to-end hardware development for autonomous platforms across air, sea, ground, and strike systems. You'll work within one of three hardware streams-Core Technology, Lethality, or DFM/DFA-to turn concepts into scalable, manufacturable hardware. The role blends high-precision design, multi-discipline integration, and rigorous testing under demanding conditions. You'll collaborate across Electrical, Manufacturing, Quality, Safety, and Test teams to accelerate mission-ready hardware. This opportunity offers impact at scale with cutting-edge defense tech and rapid hardware iteration.
