ABOUT THE ROLE

Anduril is seeking a Senior Mechanical Engineer specializing in electromechanical packaging and sensor integration to design, test, and scale mission-critical hardware across our autonomous air, sea, ground, and strike platforms.

WHAT YOU’LL DO

• Own enclosures, sensor integration, and electromechanical assemblies from requirements definition, hand calculations, and conceptual design through prototyping, testing, and volume manufacturing.
• Create high-fidelity 3D models and fully defined 2D drawing packages
• Design parts across diverse fabrication processes including designs for injection/other molding, precision 3/5-axis CNC machining, complex weldments, sheet metal, composite layups, and structural adhesive bonding.
• Apply first-principles engineering and FEA/hand calculations to validate structural, thermal, and vibrational performance under harsh operational and environmental conditions.
• Perform 1D/3D tolerance stacks, DFMEAs, and tool-access assessments early in development to de-risk production bottlenecks and scale throughput.
• Build physical prototypes, author detailed test plans, and run functional testing (environmental, dynamic, bench-top, or live arena/range tests depending on track).
• Collaborate with Electrical, Systems, Mechanical, Manufacturing, Quality, Safety, and Test teams, as well as external suppliers, to solve urgent hardware bottlenecks.

REQUIRED QUALIFICATIONS

• Bachelor's, Master’s, or PhD degree in Mechanical Engineering, Aerospace Engineering, Manufacturing Engineering, or a related discipline.
• 4+ years of professional mechanical design experience taking physical hardware from initial concept through fabrication and functional test or LRIP.
• Proficiency in parametric 3D CAD (NX preferred, 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.
• Professional experience applying statics, dynamics, material selection, heat transfer, and structural mechanics to hardware design problems.
• Experience designing hardware with Design for Manufacturability and Assembly (DFM/DFA) in mind for future volume production (e.g., fast-paced automotive, robotics, aerospace, or marine environments).
• Experience designing tightly integrated electromechanical systems (dense PCBA packaging, active/passive thermal management, RF/EMI shielding, harness routing, and environmental sealing / IP ratings).
• Prior experience in defense, maritime, optics, automotive, or other highly regulated hardware development environments.
• Eligible for U.S. Security Clearance (DoD Secret, Top Secret, or DOE Q)
• Up to 15% travel

PREFERRED QUALIFICATIONS

• Proficiency with FEA tools (Abaqus, ANSYS, or equivalent) for structural, thermal, or dynamic analysis.
• Deep expertise in tooling design, high-volume injection molding, robotic/manual weldment design, structural bonding, or building visual standard operating procedures (SOPs).
• Familiarity with ECAD tools (e.g., Altium Designer) or basic PCB design / schematic review.

US Salary Range

$146,000 — $194,000 USD
