About the Company

General Matter is enriching uranium in America.

Our goal is to design, build, and operate the world’s lowest-cost enrichment services in the United States.

Our mission is to restore America’s ability to produce nuclear fuel—fuel that will power AI, advanced manufacturing, critical industries, and the next generation of nuclear reactors.

Ultimately, our work will help power national ambitions and enable a high-energy society.

We were incubated by Founders Fund, like Anduril and Palantir before us, and are backed by top-tier investors. 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.

About This Role

As Production Supervisor at General Matter, you'll run a shift across the welding and process piping cells at our new manufacturing site in Paducah, Kentucky, which produces process piping and structural steel fabrications for the nuclear industry. This is a hands-on leadership role. You'll spend about 60% of your time on the floor coaching fitters, welders and operators, solving problems at the cell and keeping automated equipment running. The other 40% goes to driving the KPIs that show how the shift is performing. You'll be here from the start: commissioning new cells and equipment, building the crews, and setting the standard for safe, on-schedule work that holds up in an NRC-regulated quality environment.

The work happens on an active fabrication floor with welding, grinding, overhead cranes and forklifts. PPE is required, and you'll need to stand and walk for long periods and lift up to 50 lbs, with or without reasonable accommodation. You'll work assigned shifts, including off-shift coverage while the site starts up.

If you seek high impact and are excited by fast-paced, intense, Skunkworks-style projects, we encourage you to apply to join our team.

Responsibilities

Lead the shift on the floor: run shift start-up and tier meetings, assign work by cell, and stay at the point of fabrication coaching fit-up, welding and assembly on pipe spools and structural steel.
Own shift KPIs (schedule attainment, first-pass yield, weld repair rate, OEE and downtime on automated equipment, units per labor hour, overtime and safety) and act on them daily through the shift KPI board and handoffs.
Run and improve automated and mechanized fabrication equipment, such as orbital and robotic welding, pipe positioners and CNC cutting, partnering with Maintenance and Weld Development on setup, troubleshooting and uptime.
Ensure work follows approved procedures, drawings and welder qualifications, with traceability that meets a nuclear quality and safety program (10 CFR Part 70), and support Quality's stop-work authority.
Build and develop the crew: help hire and train shift/cell leads and operators, write and maintain standard work, and keep the training matrix current.
Lead a strong safety culture on the shift, covering hot work, lifting and rigging, cranes and forklifts, PPE, near-miss reporting and 5S.

Basic Qualifications

Evidence of exceptional ability (prior projects, portfolio of work, completed products, etc.).
5+ years in process piping and/or steel fabrication, including 2+ years supervising or leading a shift or crew of welders, fitters and operators.
Solid hands-on welding background, with working knowledge of GTAW, GMAW, FCAW and SMAW, pipe and structural fit-up, and reading isometrics and shop drawings.
Strong understanding of automated or mechanized fabrication equipment (orbital or robotic welding, positioners, CNC plasma/laser cutting) and basic PLC/HMI operation.
Demonstrated use of production KPIs to run a shift, with experience tracking and improving schedule attainment, first-pass yield, rework and equipment uptime.
Ability to find the root cause of fit-up, weld and equipment problems at the cell, and to make clear calls from first principles when you only have partial information.
