We are seeking a Prototype Fabricator to join our Detroit‑based state‑of‑the‑art prototyping facility. This is not a standard machine shop position - you'll work with some of the most advanced tools in the industry including metal 3D printers, tube lasers, multi‑axis mills, lathes, and custom fixturing systems.

This role is ideal for a highly adaptable, technically‑minded individual who thrives in fast‑paced environments. The right candidate will be able to be “on call” when a part is urgently needed, day or night, as needed to make it. On the flip side, your day‑to‑day schedule is extremely flexible, and you'll often have lighter periods or ad‑hoc time off when the schedule allows.

• Operate a wide range of fabrication tools including:
  • 5‑axis CNC mills and lathes
  • Metal 3D printers
  • Tube and flat‑bed lasers
  • Waterjets, presses, and high‑precision manual tools
• Prepare CAM programs in Mastercam, Fusion 360, or similar tools.
• Work from Solid Works models and technical drawings to produce high‑tolerance parts.
• Collaborate closely with engineering teams to iterate on part designs in real time.
• Help develop custom fixturing, jigs, and one‑off assemblies for rapid prototyping.
• Assist in maintaining, upgrading, and tuning machines and shop infrastructure.
• Participate in design for manufacturability (DFM) reviews and provide direct feedback to engineers.
• Occasionally assist with integration or test setups when needed.

• 5+ years of hands‑on experience in a fabrication or prototyping shop environment.
• Intermediate experience with CAM software such as Fusion 360 CAM, Solid Works CAM, Onshape CAM, or Feature
  
  CAM.
• Proficient with modern CNC machine operations and part inspection.
• Working knowledge of Solid Works (or similar CAD tools).
• Ability to interpret and execute mechanical drawings and GD&T.
• Familiarity with common materials (aluminum, titanium, stainless steel, plastics, etc.) and their machining characteristics.
• Comfortable with non‑standard hours, including occasional late‑night or weekend requests.

• Experience with additive manufacturing (especially metal 3D printing or hybrid machines).
• Deep knowledge of multi‑axis milling, fixturing, and work holding strategies.
• Experience building parts for aerospace, robotics, or optics applications.
• Familiarity with vacuum‑compatible fabrication, TIG welding, or thermal test setups.

• Competitive Compensation – A salary package aligned with industry standards and your experience.
• Equity Opportunities – Take part in our success with stock options.
• Flexible Work Environment – Enjoy working from our office or in a hybrid work setup with the flexibility to work remotely part of the week. We require a minimum of 3 days per week in our office to support collaboration and team culture. (LA Office only)
• Unlimited PTO – Take the time you need with our flexible, trust‑based vacation policy, including paid holidays. We encourage everyone to rest, recharge, and take care of themselves.
• Health & Wellness – Comprehensive medical, dental, and vision coverage with 100% of the premium paid by the employer for employees.
• Cutting‑Edge Tools – Get access to the latest hardware and software you need to do your best work.
• Mission‑Driven Culture – Be part of a team working on meaningful challenges with real‑world impact.
• Inclusive Team – We foster a supportive and diverse workplace where all voices are valued.
