Job description

About the Job

As a Battery Mechanical Engineer, you will conduct the mechanical design, thermal management, and structural analysis of high-voltage and low-voltage battery packs and energy storage modules. The right person for this role has a strong command of mechanical design, thermal runaway mitigation, and structural design principles, as well as a solid handle on structural/thermal FEA tools. If you are someone who is hardware-focused, detail-oriented, and eager to own critical battery hardware from concept through deployment, then this role is for you.

What you'll do

• Perform CAD design of battery modules, enclosures, structural support frames, and thermal management components.
• Perform finite element analysis (FEA) and computational fluid dynamics (CFD) to evaluate structural and thermal systems, including thermal runaway propagation mitigation.
• Generate, review, and release high-quality engineering drawings and product definitions.
• Collaborate extensively with electrical engineering, battery management systems (BMS) software, and manufacturing teams to integrate cell-level hardware into system-level architectures.
• Support prototyping, environmental testing (vibration, shock, thermal cycling, and penetration testing), and manufacturing operations onsite.
• Own the development of critical battery subsystems from cradle to grave.

Required qualifications

• 5+ years of experience performing mechanical design and analysis of complex hardware, ideally involving battery modules or power systems.
• A bachelor's degree in mechanical engineering, aerospace engineering, or similar.
• Prior experience operating advanced CAD software (such as NX or SolidWorks) and FEA/CFD software.
• A solid understanding of hardware manufacturability, material selection, and Geometric Dimensioning and Tolerancing (GD&T).
• Strong communication and collaborative skills.
• Ability to travel to other Anduril sites, customer sites, or supplier sites as business demand dictates (anticipated 10-25% travel).
• Ability to obtain and hold a U.S. Secret Security Clearance.

Preferred qualifications

• Exhibits strong initiative and ownership of complex engineering tasks.
• Experience with NX CAD software and/or Abaqus FEA softwae.
• Direct experience designing lithium-ion battery enclosures, cell-to-pack packaging, busbars, and high-voltage safety systems.
• Familiarity with environmental testing standards for high-reliability applications (such as MIL-STD-810, UN 38.3, or DO-160).
• Expertise in engineering tool development in Microsoft Excel, MATLAB, and/or Python.
