About the Role
We are seeking a Prototype Machinist to join our Los Angeles-based state-of-the-art prototyping facility. We’re building a state of the art prototyping facility to machine some of the world’s most challenging materials from glass, titanium, to exotic wire EDM’d parts; this is not a standard machine shop position.
This role is ideal for a highly adaptable, technically-minded individual who thrives in fast-paced environments. We’re looking for someone to sit with the team day in and day out to help push back on the team’s wild unmanufacturable designs. While this is a full time position, the job has an on-call component - when a part is urgently needed, day or night, you may be the one called 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.
What You’ll Do
•
Operate a wide range of fabrication tools including:
•
3D printers
•
5-axis CNC mills and live tooling lathes
•
Tube and flat-bed lasers
•
Waterjets, wire EDM, and high-precision manual tools
•
Participate in engineering design reviews to evaluate manufacturability
•
Collaborate closely with engineering teams to iterate on part designs in real time.
•
Help design novel machining processes and methodologies that will be used in our Michigan production facility
•
Work from SolidWorks models and technical drawings to produce high-tolerance parts.
•
Prepare CAM programs in Mastercam, Fusion 360, or similar tools.
•
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.
Basic Qualifications
•
5+ years of hands-on experience in an engineering prototyping shop or machine shop environment.
•
Working knowledge of SolidWorks (or similar CAD tools).
•
Significant experience with CAM software such as Mastercam or Fusion CAM.
•
Proficient with modern CNC machine operations and part inspection.
•
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 occasional non-standard hours, including occasional late-night or weekend requests.
Preferred Qualifications
•
Experience with light duty fabrication - TIG welding, laser cell operation, slip rolling, fixturing and fit-up. “A grinder and paint make me the welder I aint” is our moto in a prototype environment
•
Experience designing test fixturing and metrology
•
Willing to shoot paint - grab the hvlp and step into the booth. Doesn’t have to be pretty, just can’t be boogers.
•
Deep knowledge of multi-axis milling, fixturing, and workholding strategies.
•
Experience building parts for aerospace, robotics, or optics applications.
•
Familiarity with vacuum-compatible fabrication.
What We Offer
•
Build out a team of R&D specialists.
•
High-trust, flexible scheduling.
•
Direct impact on rapid iteration of hardware bound for space, field ops, or high-performance systems.
•
A culture that respects craftsmanship, iteration speed, and creative autonomy.
