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 TEAM

The Lethality team designs, builds, tests, and fields mechanical warhead and ordnance systems that integrate directly with Anduril platforms.

Our engineers work across mechanical design, manufacturing, analysis, testing, safety, and vehicle integration to move new concepts from an idea to tested hardware quickly. The team is highly hands‑on and built for engineers who want to design new products, solve difficult problems, and see their decisions become real hardware.

ABOUT THE JOB

The Lethality Team is looking for a Mechanical Engineer to help develop the next generation of warhead and ordnance systems.

You will design new mechanical hardware, work directly with the people building it, test your designs, and use the results to make the next iteration better.

Yes, you may actually get paid to blow things up.

You do not need to arrive as a warhead expert. We are looking for strong mechanical engineers with practical design experience, sound engineering judgment, curiosity, and the ability to learn a highly specialized domain quickly.

WHAT YOU'LL DO

• Design new mechanical hardware from requirements and early concepts through detailed CAD, drawings, fabrication, assembly, and test.
• Turn engineering ideas into manufacturable products by making practical decisions around materials, tolerances, interfaces, manufacturing methods, cost, and assembly.
• Build, test, and improve your designs by working directly with manufacturing, technicians, analysis, and test teams to identify problems and drive the next iteration.
• Integrate your hardware into larger systems by partnering with vehicle, systems, safety, and other engineering teams to resolve interfaces and technical tradeoffs.
• Grow your technical ownership by progressing from defined components and workstreams toward increasingly independent subsystem design and decision-making.
• IMPACT YOU'LL HAVE
  • Deliver new lethality hardware that directly supports U.S. and allied warfighters.
  • Take products from early concepts to physical hardware instead of maintaining legacy designs.
  • Develop specialized expertise in warhead and ordnance engineering alongside experienced technical leaders.
  • See the direct impact of your engineering decisions through manufacturing, integration, and live testing.

REQUIRED QUALIFICATIONS

• BS in Mechanical Engineering, Aerospace Engineering, or a related technical field.
• 1 year of practical, end-to-end mechanical product design experience.
• Demonstrated experience taking a new mechanical product or design through multiple stages of development, such as concept, CAD, drawings, fabrication, assembly, testing, and iteration.
• Strong mechanical design fundamentals, including materials, tolerances, interfaces, manufacturing processes, and design for manufacturability.
• Professional CAD experience creating mechanical parts, assemblies, and engineering drawings, with the ability to explain design decisions, tradeoffs, and how test or engineering data informed the design.
• Ability to work onsite in Costa Mesa, travel for testing as required, and obtain and maintain a U.S. security clearance.
• In this role, you will be subject to pre-employment and randomized substance screening, as required by the Company.

PREFERRED QUALIFICATIONS

• Experience with NX, Teamcenter, or comparable CAD/PLM tools.
• Experience applying GD&T, tolerance analysis, and design for CNC machining or precision manufacturing.
• Experience developing hardware in a fast-paced R&D or new-product-development environment.
• Experience in aerospace, defense, space, robotics, automotive, or other complex physical-product industries.
• Experience supporting mechanical, environmental, dynamic, or system-level testing and using results to improve a design.
• Exposure to ordnance, munitions, energetics, explosives, weapons systems, or other defense hardware.

$129,000 — $171,000 USD

The salary range for this role is an estimate based on a wide range of compensation factors, inclusive of base salary only. Actual salary offer may vary based on (but not limited to) 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.
