Lead Embedded Software Engineer

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.

As a General Matter Lead Embedded Software Engineer, you will serve as a technical leader for the embedded software that directly controls our systems while managing and mentoring a small team of engineers. You will own critical software architecture and technical decisions, remain deeply hands-on in development, and help guide the growth and execution of your direct reports. Your code will command actuators, process high-speed signals, and operate in applications where safety, reliability, and precision are essential.

You will set technical direction, establish engineering standards and best practices, and lead the design and development of complex embedded software across the system. You will also provide day-to-day technical mentorship, feedback, and support to a small number of direct reports. You will work closely with electrical engineers, software engineers, chemical engineers, manufacturing engineers, nuclear engineers, materials scientists, and physicists to translate system requirements into robust, production-ready software.

If you're motivated by solving difficult technical problems, setting the technical bar for embedded systems, and helping develop a small team while staying close to the work, this is the role for you.

• Architect and develop safety-critical embedded software that powers General Matter's industrial systems with reliability and precision.

• Manage, mentor, and develop a small team of engineers while remaining hands-on in technical execution and day-to-day problem solving.

• Build low-level firmware in C/C++, and Rust to control electromechanical actuators, process high-speed sensor data, and execute fault-tolerant control logic.

• Design robust control architectures, state machines, and data acquisition systems for mission-critical hardware.

• Own software from development through deployment by creating automated build, test, and validation infrastructure.

• Partner closely with hardware, electrical, and controls engineers to bring up new systems, integrate firmware with hardware, and troubleshoot complex electromechanical challenges.

• Perform safety analyses and validate control logic to ensure deterministic behavior and functional safety under both normal and fault conditions.

• Debug real-world embedded systems using oscilloscopes, logic analyzers, protocol analyzers, and other laboratory
