<p><strong>About the Company</strong></p> <p><u>General Matter enriches uranium.</u></p> <p>We are designing, building, and operating the world’s lowest-cost enrichment services, here in the US. </p> <p>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. </p> <p>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.</p> <p>Our mssion 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. </p> <p>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. </p> <p>Our lean, world-class team of engineers and operators is applying a first-principles approach to solving the problem of nuclear fuel production. </p> <p>We are a mission-driven company with a culture of urgency, accountability, and transparency. </p> <p>Help us build a high-energy society by making the cleanest, safest form of baseload energy the most affordable. </p> <p><strong>About This Role</strong></p> <p data-prosemirror-content-type="node" data-prosemirror-node-name="paragraph" data-prosemirror-node-block="true" data-pm-slice="1 1 []">As a General Matter Software Engineer, you will develop performant, safe and high-quality software to directly control our systems. Your code will be responsible for commanding actuators and processing high-speed signals in applications where safety and accuracy are exceedingly important. You will work closely with cross-functional teams, including electrical engineers, software engineers, chemical engineers, manufacturing engineers, nuclear engineers, materials scientists and physicists.
