Battery Mechanical Engineer

The role

You will conduct mechanical design, thermal management, and structural analysis of high-voltage and low-voltage battery packs and energy storage modules. You will own critical battery hardware from concept through deployment.

What you will 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.
• Generate, review, and release high-quality engineering drawings and product definitions.
• Collaborate with electrical engineering, battery management systems (BMS) software, and manufacturing teams.
• Support prototyping, environmental 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 (anticipated 10-25% travel).
• Ability to obtain and hold a U.S. Secret Security Clearance.

Nice to have

• 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

Benefits

• Comprehensive, competitive benefits package available at little to no cost to employees

Before you apply

• Ability to obtain and hold a U.S. Secret Security Clearance.
• Consent to pre-employment risk, integrity, and due diligence screening.
