CNC program lead

About Linewise

Linewise captures how physical things are made, from the first design to the final assembly, and turns it into training data for frontier AI and robotics models. Our long-term aim is Physical RSI: recursive self-improvement for the physical world, where AI helps engineers design and plan, robots help build and inspect, and each generation makes better machines, lines and factories for the next. This role is part of Linewise Engineering, which captures the decisions behind a part: requirements, design iterations and analysis, process plans and inspection records, including rejected designs.

About the role

This role is for an engineer who has run CNC machines and can also run a program. You'll own a CNC data program end to end: you build the network of partner machine shops, write the capture specs, review every delivery and plan the work so each one lands on spec and on time. You'll work closely with the team that builds our review tooling. It's full ownership of a data vertical.

What you'll do

• Build and manage a network of partner machine shops.
• Write the capture specs that set what each shop records and how.
• Review the quality of every delivery against the spec before it goes out.
• Plan the work across shops so each delivery lands on spec and on time.
• Work with the team that builds our review tooling, and shape it around what you see in the data.
• Catch problems early, in the spec, at the shop or in the data, and fix them at the source.

What we're looking for

• Hands-on CNC machining experience. You know what a good setup, a good part and a good process look like.
• Experience running a project or program end to end, with plans, schedules and outside partners.
• You want full ownership of a data vertical, from the first spec to the last delivery.
• You write clear specs and give direct feedback that shops can act on.
• Good written and spoken English.

Nice to have

• CAM or toolpath programming experience.
• A shop-floor or manufacturing engineering background.
• Experience managing suppliers.

How we work

• You own your area end to end, from the first spec to the final delivery.
• You work closely with engineers, operators and researchers.
• English is the working language. We're based in San Francisco, with global operations.
