Prototype Technician

The role

You will prepare, fabricate, and inspect 3D-printed prototypes for the NEO humanoid robot. You will work with engineers to create or modify parts in CAD and maintain the prototyping workspace.

What you will do

• Prepare, fabricate, and inspect 3D-printed prototypes for NEO.
• Create or modify prototype parts and simple fixtures in CAD.
• Select materials and build parameters for intended use.
• Prepare print files, operate and maintain printers, and complete post-processing.
• Troubleshoot failed builds and inspect critical dimensions.
• Support assembly checks and functional testing.
• Deliver labeled, inspected prototypes that meet dimensional, fit, and functional criteria.
• Improve first-pass build success and turnaround by tracking failures and testing process changes.
• Keep printers ready through calibration, preventive maintenance, and troubleshooting.
• Maintain revision-controlled CAD, print files, process settings, and inspection records.

Required qualifications

• 1–3 years of hands-on experience in additive manufacturing, rapid prototyping, model making, or manufacturing, including regular 3D printing.
• Ability to prepare, slice, set up, and troubleshoot builds using at least one additive process, such as FDM/FFF or SLA.
• Ability to perform routine printer maintenance.
• Working knowledge of a 3D CAD tool, including basic part modifications.
• Ability to interpret drawings, dimensions, and mechanical fits.
• Experience with calipers or similar inspection tools.
• Experience with basic post-processing and assembly.
• Ability to maintain accurate build and inspection records.
• Ability to work on-site in San Carlos, CA.
• Ability to follow equipment and material-handling procedures.
• Ability to communicate clearly with engineers.

Nice to have

• Experience with multiple additive processes, such as FDM/FFF, SLA/DLP, SLS, or MJF, and a range of engineering polymers or resins.
• Experience managing material drying and storage, support removal, curing, finishing, and dimensional consistency across repeated builds.
• Familiarity with parametric CAD tools such as SolidWorks, NX, Creo, or Fusion.
• Basic GD&T.
• Fixture or assembly-aid design.
• Robotics, automotive, or aerospace prototyping experience.
• Technical training in additive manufacturing, machining, or a related field.

Benefits

• Comprehensive medical, dental, and vision coverage
• Generous paid time off, company holidays, and parental leave
• 401(k) plan with company match (100% on the first 3% of contributions, 50% on the next 2%)
• Flexible Spending Accounts (FSA) and Health Savings Accounts (HSA) options
• Commuter benefits (transit and parking)
• Short-term and long-term disability, and life insurance
• Employee Assistance Program (EAP) for mental health, financial, and personal support
• Onsite snacks and catered lunches
