Job description

Anduril Industries is a defense technology company with a mission to transform U.S. and allied military capabilities with advanced technology. By bringing the expertise, technology, and business model of the 21st century’s most innovative companies to the defense industry, Anduril is changing how military systems are designed, built and sold. Anduril’s family of systems is powered by Lattice OS, an AI‑powered operating system that turns thousands of data streams into a realtime, 3D command and control center. As the world enters an era of strategic competition, Anduril is committed to bringing cutting‑edge autonomy, AI, computer vision, sensor fusion, and networking technology to the military in months, not years.

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 software.
• 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.

Salary Range

US Salary Range: $129,000 – $171,000 USD (base salary only). Actual salary offer may vary based on work experience, education and/or training, critical skills, and/or business considerations. Highly competitive equity grants are included in the majority of full‑time offers and are considered part of Anduril’s total compensation package.

Benefits

At Anduril, we invest in our people. Our comprehensive, competitive benefits package (available at little to no cost to employees) ensures you’re supported in health, recovery, and whatever comes next.
