Mechanical Design Engineer (Multiple Tracks: Core Tech, Lethality, & DFM/DFA)

ABOUT THE ROLE

Anduril is seeking exceptional, hands-on Mechanical Design Engineers to design, test, and scale mission-critical hardware across our autonomous air, sea, ground, and strike platforms. 

We are hiring across three core work-streams. Depending on your background, technical depth, and career focus, you will align with one of the following hardware teams:

• Core Technology Products: Architect foundational hardware platforms spanning aircraft, missiles, maritime vessels, and ground systems. You will lead blank-sheet mechanical packaging, tight electro-mechanical integration (thermal, RF, PCBAs), and rapid hardware iteration.
• Lethality (Warhead Design): Design and mature advanced warheads, ordnance, and munitions systems. You will bridge mechanical engineering, dynamic modeling, energetic material packaging, safety constraints, and live-fire test operations.
• Design for Excellence (DFM / DFA): Sit at the critical interface between initial CAD concepts and production reality. You will drive high-rate manufacturability, assembly optimization, drawing standards, and tooling strategies to ensure hardware can scale at the speed of mission need.

WHAT YOU’LL DO

• End-to-End Hardware Ownership: Own components and complex mechanical assemblies from requirements definition, hand calculations, and conceptual design through prototyping, testing, and volume manufacturing.
• Rigorous Mechanical Design: Create high-fidelity 3D models and fully defined 2D drawing packages in strict accordance with ASME Y14.5 (GD&T) standards.
• Multi-Discipline Engineering: Design parts across diverse fabrication processes—including precision 3/5-axis CNC machining, complex weldments, sheet metal, injection molding, composite layups, and structural adhesive bonding.
• Analysis & Simulation: Apply first-principles engineering and FEA/hand calculations to validate structural, thermal, vibrational, and tolerance-stackup performance under harsh operational conditions.
• Design for Manufacturing & Assembly (DFM/DFA): Perform 1D/3D tolerance stacks, DFMEAs, and tool-access assessments early in development to de-risk production bottlenecks and scale throughput.
• Prototyping & Test Execution: Build physical prototypes, author detailed test plans, and run functional testing (environmental, dynamic, bench-top, or live arena/range tests depending on track).
• Cross-Functional Execution: Collaborate shoulder-to-shoulder with Electrical, Manufacturing, Quality, Safety, and Test teams, as well as external suppliers, to solve urgent hardware bottlenecks.

REQUIRED QUALIFICATIONS
•      Bachelor's degree in Mechanical Engineering, Aerospace Engineering, Manufacturing Engineering, or a related discipline, or equivalent combination of education and work experience.
•      2+ years of professional mechanical design experience taking physical hardware from initial concept through fabrication and functional test. 
•      Proficiency in parametric 3D CAD (NX, SolidWorks, or Creo) and modern PLM/PDM environments (e.g., Teamcenter).
•      Working knowledge of engineering drawings and practical application of ASME Y14.5 GD&T and tolerance stack-up analysis.
•      Hands-on prototyping and fabrication experience, including root-cause analysis of manufacturing and hardware defects.
•      Coursework or professional experience applying statics, dynamics, material selection, heat transfer, and structural mechanics to hardware design problems.
•      Must be eligible to obtain and maintain a U.S. Security Clearance.

PREFERRED QUALIFICATIONS
•      Master's degree or PhD in Mechanical Engineering, Aerospace Engineering, or a related field.
•      Prior experience in defense, aerospace, or other highly regulated hardware development environments.
•      Proficiency with FEA tools (Abaqus, ANSYS, or equivalent) for structural, thermal, or dynamic analysis.
•      Lethality Track: Experience with naval ordnance, warheads, energetic materials, DoD weapons safety boards, high-rate dynamic modeling, or live-fire arena testing.
•      Core Tech Track: Experience designing tightly integrated electromechanical systems (dense PCBA packaging, active/passive thermal management, RF/EMI shielding, harness routing).
•      DFM/DFA Track: Deep expertise in tooling design, high-volume injection molding, robotic/manual weldment design, structural bonding, or building visual standard operating procedures (SOPs).
•      Active U.S. Security Clearance (DoD Secret, Top Secret, or DOE Q).

Some roles may require travel for field or range testing (up to 25%, primarily within Lethality work-streams)
