Defense robotics startup building attritable autonomous underwater vehicles for denied environments

Senior Mechanical Engineer

Los AngelesOn-site$140K - $220K5 - 7 years
You'll spend Monday mornings reviewing pressure-test data from hull prototypes that failed at depth, then sketch weld fixes over lunch with the fabrication lead. By Thursday you're running modal analysis on a new thruster mount, deciding whether titanium or 6061-T6 wins the weight budget. This is hands-on work: Fusion 360 to CNC to tank testing, with zero buffer between your CAD and the ocean.

What they're looking for

  • 5-7 years designing sealed mechanical systems for marine, aerospace, or similarly harsh environments
  • Deep fluency in structural FEA and fatigue analysis for components under cyclic hydrostatic loading
  • Direct experience with composite or metallic pressure vessel design, including DfM for bonded/welded joints
  • Proven ownership of hardware through build, test, and iteration cycles — not paper-only designs
  • Comfort working in small, co-located teams where you own your cal stack and your grease stains
