Embedded Software Engineer, Motor Control & Real-Time Systems

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.

We are seeking an Embedded Software Engineer to develop the real-time control software, motor drive firmware, and device drivers that directly command test stands and production systems. This role sits where real-time embedded engineering meets motor control. You'll turn control algorithms into deterministic, fault-tolerant code that closes high-rate control loops, drives power electronics, coordinates distributed actuators over fieldbus networks, and acquires high-speed signals from scientific instrumentation. Safety and accuracy matter enormously in all of it. You will help define the real-time architecture, driver standards, and hardware interfaces of mission-critical embedded systems across R&D, manufacturing/test, and plant operations, working hands-on with hardware from early prototypes through deployed systems. If you seek high impact and are excited by fast-paced, intense, Skunkworks-style projects, we encourage you to apply to join our team.

• Architect and develop deterministic, safety-critical control software on real-time Linux (e.g., PREEMPT_RT) and embedded microcontroller/DSP targets, including scheduling, timing, and fault-tolerant control logic.

• Define real-time architecture, driver standards, and hardware interface conventions shared across R&D, test, and production systems.

• Implement and optimize motor control algorithms in embedded firmware, including field-oriented control, sensorless control, and high-rate closed-loop current and torque control.

• Develop low-level drive firmware for PWM generation, synchronized ADC sampling, current and voltage sensing, and motor feedback interfaces for power electronics and inverters.

• Implement estimation, monitoring, and protection functions (state and fault estimation, overcurrent and overvoltage protection) to maximize system safety and reliability.

• Build and maintain industrial fieldbus masters and stacks (e.g., EtherCAT, CAN/CANopen, EtherNet/IP) for hard real-time, high-rate closed-loop control of distributed actuators, drives, and I/O.

• Write drivers and interfaces for scientific instrumentation, sensors, and data acquisition hardware for high-speed, kHz-class acquisition across low-level protocols and buses (e.g., SPI, I2C, serial, USB, PCIe, Ethernet).

• Own software from development through deployment by building automated build, test, and validation infrastructure, including software-in-the-loop (SIL) and hardware-in-the-loop (HIL) frameworks for motor control and
