About the role

About the Company General Matter enriches uranium.
Reliable, low-cost enrichment is the catalyst for the nuclear Renaissance now under way.
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.

Develop, prove out, and optimize CNC programs for 5-axis machining centers, CNC lathes, and Swiss-type lathes with live/driven tooling and sub-spindle operations.
Generate and maintain CAM programs, post-processors, tool libraries, and setup sheets
Lead first-article runs and process prove-out
drive cycle-time reduction, tool-life improvement, and scrap reduction without compromising tolerance or surface finish.
Author and maintain process documentation - setup sheets, work instructions, tooling lists - to a standard that supports traceability and repeatability.
Partner with Manufacturing and Quality Engineering on tolerance feasibility, inspection planning, and first-article inspection (FAI / AS9102) requirements.
Support equipment commissioning and capability studies as new machine tools are installed during facility ramp-up.
Identify and recommend tooling, software, and process improvements to support the transition from prototype to rate production.
Generate and maintain CAM programs, post-processors, tool libraries, and setup sheets; verify programs through simulation/verification before floor release.
Lead first-article runs and process prove-out; drive cycle-time reduction, tool-life improvement, and scrap reduction without compromising tolerance or surface finish.

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.
Practical knowledge of work-holding, fixturing, tooling selection, and feeds/speeds optimization.
Comfort working in a documented quality environment with full part traceability.
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).

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.
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.
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.
