At a glance

The Additive Manufacturing team at Anduril is a high-speed development lab that turns evolving designs into physical hardware for immediate testing and iteration.
This role serves as the technical owner for FDM capabilities, managing a fleet of eight systems in a high-mix, low-volume prototype environment.
The technician will partner directly with design engineers to determine build strategies, troubleshoot failures, and ensure high-quality hardware delivery.

Own FDM builds end to end, from CAD and requirements review through file preparation, printing, post-processing, inspection, and delivery.
Operate, calibrate, and maintain a fleet of industrial and development-grade FDM printers.
Review incoming CAD for printability and identify issues with geometry, wall thickness, orientation, tolerances, mating features, supports, and clearances.
Partner with design engineers to recommend the right material, orientation, process, and build strategy based on end-use requirements.
Prepare and optimize builds using slicer software, including custom toolpath development.
Balance approximately 10–20 active jobs, sequencing work based on priority, machine availability, and technical requirements.
Troubleshoot failed prints, machine faults, calibration issues, and process drift.
Post-process parts to deliver clean, functional hardware ready for engineering use.
Verify completed work against the original request to ensure quality and quantity requirements are satisfied.
Develop and maintain print profiles, process documentation, and work instructions.

4+ years of hands-on additive manufacturing experience in a prototype lab, service bureau, or development environment (or 2 years with demonstrated end-to-end ownership).
Deep hands-on experience with FDM systems, including machine setup, calibration, build preparation, parameter optimization, and troubleshooting.
Experience owning additive builds from CAD intake through finished part, including slicer software and custom toolpaths.
Ability to evaluate CAD for printability and make sound decisions regarding material, orientation, tolerance, strength, and finish.
Demonstrated ability to troubleshoot print failures, manage multiple active jobs, and communicate technical risks.
Ability to lift up to 50 lbs.
Must be a U.S. Person due to required access to U.S. export-controlled information or facilities.

Experience with Stratasys industrial FDM systems and/or INSIGHT.
Experience with additional additive technologies such as SLA, MJF, SLS, PolyJet, or metal additive.
Experience in a high-mix, low-volume prototype environment supporting design engineers directly.
Working knowledge of NX, SolidWorks, or similar CAD tools.
Experience with composite tooling, dimensional inspection, or additive process documentation.
