About the job

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.

About This Role

As Total Rewards Manager at General Matter, you'll build and own how we pay, reward, and take care of the people restoring America's nuclear fuel supply. You'll set up our compensation and benefits infrastructure and run it day to day, and continue to mature our compensation and benefits strategy, philosophy, and implementation.

The problems here don't come with off-the-shelf answers. How do you benchmark roles that barely exist anywhere else in the country? How do you design one rewards system that works for both first-principles engineers and the plant operators and technicians who will run a nuclear facility around the clock? You'll frame the question, pull the data, build the model, and bring leadership a clear recommendation with the tradeoffs made explicit.

You'll work with a modern stack (Rippling, Carta, Pave) and you'll be expected to build your own tools with AI. This is a hands-on, strategic role working with partners across engineering, nuclear operations, infrastructure, construction, security, legal, finance and people.

If you seek high impact, want true ownership of a function, and are excited by fast-paced, intense, Skunkworks-style work, we encourage you to apply to join our team.
