Embedded Software Engineer

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 a General Matter Embedded 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.

If you're motivated by solving challenging technical problems, building software that interacts directly with the physical world, and making a tangible impact on the future of clean nuclear energy, this is the role for you.

Responsibilities

• Architect and develop safety-critical embedded software that powers General Matter's industrial systems with reliability and precision.
• Build low-level firmware in C/C++, Rust, and PLCs 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 instrumentation
• Contribute to integrated system testing, commissioning, and continuous improvement of embedded software running on production equipment.

Basic Qualifications

• Strong understanding of engineering fundamentals
• Ability to perform trade studies and make clear recommendations using first principles and engineering fundamentals even with partial information
• BS degree in computer science, engineering, math, or a STEM discipline and 5+ years of professional experience
• Development experience in C, C++, Golang, Python or Rust
• Experience with embedded or low-level systems development

Preferred Skills and Experience

• Data acquisition system setup, maintenance, and development
• Electrical hardware troubleshooting and assistance in PCBA bring-up
• Digital Signal Processing
• Low-level communication protocol debugging
• PLC/SCADA system programming experience
• Security analysis and threat modeling
• Experience in a fast-paced engineering environment or a highly technical role requiring a resourceful, entrepreneurial approach to complete tasks within tight timeframes or budget constraints.

Additional Requirements

• Ability to work extended hours and weekends as necessary.
