CNC Programmer (Mill, Lathe & Swiss)

About the Company

General Matter enriches uranium.

We are designing, building, and operating the world’s lowest-cost enrichment services, here in the US.

In the process, we are restoring America’s ability to produce nuclear fuel to power AI, advanced manufacturing and critical industries our country relies on to remain competitive.

Fuel drives the cost of advanced reactor electricity production, and enrichment drives the cost of the fuel that advanced reactors consume. Reliable, low-cost enrichment is the catalyst for the nuclear Renaissance now under way.

Our mission is to make nuclear not only the cleanest and safest source of baseload power, but also the most affordable. We believe abundant nuclear energy will lead to a post-scarcity society.

We were incubated inside Founders Fund, like Anduril and Palantir before us, and are backed by over a dozen of the world's top venture capital firms.

Our lean, world-class team of engineers and operators is applying a first-principles approach to solving the problem of nuclear fuel production.

We are a mission-driven company with a culture of urgency, accountability, and transparency.

Help us build a high-energy society by making the cleanest, safest form of baseload energy the most affordable.

CNC Programmer (Mill, Lathe & Swiss)

General Matter is seeking a highly skilled CNC Programmer with deep expertise in 5-axis milling, CNC turning, and Swiss-type lathes with live tooling. This role is responsible for developing and optimizing machining programs that support the transition from prototype development to scalable production of high-precision components in a regulated manufacturing environment.

The ideal candidate is both highly technical and process-oriented, capable of translating complex engineering designs into robust machining strategies while driving continuous improvement in cycle time, tooling performance, repeatability, and manufacturing scalability.

Basic Qualifications

• 5+ years of CNC programming experience, including hands-on programming of 5-axis milling and Swiss-type lathes with live tooling.

• Proficiency with a major CAM package — Mastercam, Esprit, GibbsCAM, or Fusion 360 — including multi-axis and mill-turn modules.

• Strong working knowledge of G-code/M-code, control platforms (e.g., Fanuc, Siemens, Citizen/Star/Tsugami Swiss controls), and post-processor behavior.

• Ability to read and interpret complex engineering drawings and apply GD&T.

• Demonstrated experience machining precision components in metals such as stainless steels, titanium, aluminum, and/or high-temperature/superalloys.

• Practical knowledge of work-holding, fixturing, tooling selection, and feeds/speeds optimization.

• Comfort working in a documented quality environment with full part traceability.

Preferred Skills and Experience

• Experience in a regulated manufacturing environment — NQA-1, AS9100, or ISO 9001 — preferably nuclear, aerospace, or defense.

• Experience supporting prototype-to-production transitions or new-facility/equipment commissioning.

• Familiarity with mill-turn machining and macro/parametric (custom macro) programming.

• Working knowledge of CMM/inspection processes and first-article inspection (FAI).

• Exposure to MES/ERP-driven shop-floor systems and digital process documentation.

• Lean manufacturing or continuous-improvement experience (cycle-time reduction, SMED, scrap reduction).

• Journeyman machinist background or formal machining/CNC technical credential.

Additional Requirements

• Physical effort including standing, lifting, and carrying equipment up to 50 lbs. unassisted.
• Must be able to work all required shift hours, overtime and/or weekends as needed
