Job description
We’re looking for a Prototyping Technician with strong 3D printing experience and a mindset for continuous improvement. You’ll be responsible not just for printing and assembling prototype parts, but for improving how we do it—tuning processes, designing fixtures, and helping us move faster without sacrificing quality.

WHAT YOU’LL DO
Run 3D printers: FDM, SLA, maybe SLS: queue jobs, dial in settings, troubleshoot, post-process
Maintain and improve print systems: Keep machines running well and upgrade workflows as needed
Optimize CAD models: Collaborate with engineers to improve printability and part quality
Design tools and fixtures: Create simple jigs or test rigs to support builds and validation
Assemble and test prototypes: Build mechanical systems and help validate functionality
Document and refine processes: Track print settings, test results, and drive improvements
Manage the lab: Maintain organization, supplies, and part flow
Automate: Identify and implement ways to automate the 3D printing workflow so you and the team can focus rapid iteration
