CNC Machinist

Weave Robotics; San Francisco (CA); On-site; USD 90,000 - 120,000; Full time

Job summary

Weave Robotics seeks a CNC Machinist to advance our in-house production and prototyping. You’ll take parts from CAD through CAM, set up tooling, and run production and prototype parts in aluminum, steel, and engineering plastics.

You’ll directly influence tolerances and fixtures, ensuring quality and smooth workflow. You’ll manage our CAM workflows with Fusion 360 or Mastercam, run 3D printers for rapid fabrication, and contribute to a fast-paced, prototype-driven shop culture.

Qualifications

• 3+ years programming and machining your own parts on CNC mills
• CAM fluency in Fusion 360, Mastercam, or similar, with the tooling and feeds/speeds judgment to back your own programs.
• Inspection skill: confident with precision measurement and first-article discipline; you catch your own scrap before it travels.
• Prototype-shop temperament: small batches, frequent changeovers, and new parts weekly, with the setup creativity to support pace and flux.
• Pride in the work. Parts you'd sign. Degrees not required; your parts are your portfolio.

Responsibilities

• Own parts CAM to first article. Program in CAM (Fusion 360 or similar), select tooling and workholding, set up, prove out, and cut production and prototype parts in aluminum, steels, and engineering plastics.
• Hold the tolerances that matter. Read GD&T, know which callouts drive function, and inspect your own work with mics, indicators, and gauges before anyone asks.
• Run the additive side. Own our 3D printers (FDM/SLA-class): job preparation, material handling, and knowing when a part needs to be printed instead of machined.
• Keep the shop sharp. Tool library, machine maintenance schedules, stock organization, and the standards that keep the shop humming.
• Make parts easier to make. Give engineers direct DFM feedback: a fillet radius, a datum change, or a tolerance relaxation that cuts cycle time without cutting function.

Job description

Join Us, and Ship Robots

Weave was founded to build the robots we’d want to have in our own home. We believe the next generation of robotics will transform everyday life by enabling people to do more and to reclaim time to spend on what’s important.

Join Us, and Ship Robots

Weave was founded to build the robots we’d want to have in our own home. We believe the next generation of robotics will transform everyday life by enabling people to do more and to reclaim time to spend on what’s important.
We also believe robots are in a sense like any other product: to matter, they have to ship. Our robots are already operating in real homes and businesses, giving us the opportunity to rapidly improve from real-world experience. With a growing team, strong customer demand, and capital for expansion, we’re entering an exciting stage of growth—and we’re looking for people with exceptional talent and standards to help bring home robotics to millions of households.

The Role

At Weave we build practical and delightful robots that benefit as many people as possible. We're already publicly shipping some of the first bimanual robots you can buy, but we'll be defined as a company by how quickly we can build and ship orders of magnitude more. To that end we're now growing our assembly and manufacturing teams.
We machine our robots' structural parts in our own shop. As a CNC Machinist at Weave, you'll take parts from CAD through CAM, setup, first article, and production runs, and help decide how the shop is equipped as we grow. You'll also run our 3D printers and other rapid fabrication so engineering can iterate fast.

Responsibilities

• Own parts CAM to first article. Program in CAM (Fusion 360 or similar), select tooling and workholding, set up, prove out, and cut production and prototype parts in aluminum, steels, and engineering plastics.
• Hold the tolerances that matter. Read GD&T, know which callouts drive function, and inspect your own work with mics, indicators, and gauges before anyone asks.
• Run the additive side. Own our 3D printers (FDM/SLA-class): job preparation, material handling, and knowing when a part needs to be printed instead of machined.
• Keep the shop sharp. Tool library, machine maintenance schedules, stock organization, and the standards that keep the shop humming.
• Make parts easier to make. Give engineers direct DFM feedback: a fillet radius, a datum change, or a tolerance relaxation that cuts cycle time without cutting function.
  

What You'll Bring

• 3+ years programming and machining your own parts on CNC mills (lathe experience welcome): a true programmer/operator, not a button-pusher or a CAM-only programmer.
• CAM fluency in Fusion 360, Mastercam, or similar, with the tooling and feeds/speeds judgment to back your own programs.
• Inspection skill: confident with precision measurement and first-article discipline; you catch your own scrap before it travels.
• Prototype-shop temperament: small batches, frequent changeovers, and new parts weekly, with the setup creativity to support pace and flux.
• Pride in the work. Parts you'd sign. Degrees not required; your parts are your portfolio.
  

Nice to Have

• 5-axis or 4-axis experience.
• Working-lead experience: planning shop workload and mentoring another machinist.
• Fixture design experience for machining or assembly.
