Senior CNC Machinist

Foundation•San Francisco, CA

1d•$120,000 - $160,000

About The Position

The Senior CNC Machinist will manufacture high-precision components for humanoid robots and actuators, helping move production from prototypes to scalable manufacturing. The role collaborates with engineering and manufacturing teams to refine designs and machining processes for quality, efficiency, and cost-effectiveness. It also contributes to automated machining and handling processes, high-throughput manufacturing systems, and in-house production of custom components. The position involves operating and programming CNC and traditional machining equipment, supporting production ramp-up, and ensuring machined parts meet specifications and tolerances. The machinist will work with multiple materials and projects in a dynamic, scaling production environment.

Requirements

At least 5 years of experience as a machinist, focused on high-precision manufacturing.
Proficiency operating and programming CNC machines and traditional machining tools such as mills, lathes, and grinders.
Experience designing automated process lines and setting up systems for mass production of precision components.
Experience evaluating and selecting machining equipment, tooling, and manufacturing methods based on part requirements, tolerances, and production volume.
Ability to support the transition from low-volume prototyping to scalable, high-throughput machining processes.
Familiarity with production ramp-up planning, fixture design, toolpath optimization, and cycle time reduction.
Skill working with materials including aluminum, steel, and advanced composites.
Ability to read and interpret engineering drawings, CAD files, and technical blueprints.
Strong focus on precision and meeting design specifications and tolerances.
Thorough understanding of quality assurance processes and measuring tools such as calipers, micrometers, and CMMs.
Resourcefulness in troubleshooting machining issues, optimizing setups, and resolving production bottlenecks.
Ability to collaborate with engineers on manufacturability and cost efficiency.
Comfort managing multiple machining projects in a dynamic environment and adapting to new technologies, tools, and workflows.
