Battery Mechanical Engineer
About this role
Anduril Industries seeks an experienced Battery Mechanical Engineer to design, analyze, and optimize high-voltage and low-voltage battery packs for advanced defense systems. You'll own critical battery subsystems from concept through deployment, performing CAD design, structural/thermal analysis, and cross-functional collaboration with electrical and manufacturing teams.
What you'll do
- Design battery modules, enclosures, structural frames, and thermal management components using advanced CAD software
- Conduct FEA and CFD analysis to evaluate structural integrity and thermal performance, including thermal runaway mitigation
- Create and review engineering drawings, specifications, and product definitions for manufacturing
- Collaborate with electrical engineering, BMS software, and manufacturing to integrate cell-level hardware into system architectures
- Support prototyping, environmental testing (vibration, shock, thermal cycling), and on-site manufacturing operations
- Own battery subsystem development lifecycle from initial concept to field deployment
What they're looking for
- Mechanical design and analysis of complex hardware systems
- CAD software (NX, SolidWorks)
- FEA/CFD analysis tools (Abaqus preferred)
- Thermal management and thermal runaway mitigation
- GD&T and material selection
- Battery enclosure and lithium-ion pack design
- Environmental testing standards (MIL-STD-810, UN 38.3, DO-160)
- MATLAB, Python, or Microsoft Excel for engineering tools
Benefits
- Competitive equity grants
- Top-tier benefits package for full-time employees
- Work on cutting-edge defense technology with AI and autonomy systems
