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 We are seeking a Controls and Systems Software Engineer to design and implement the control and automation software stack for test stands and production systems. This role sits at the intersection of industrial automation and systems software engineering, and is responsible for building reliable, maintainable, and safety-critical control systems spanning PLCs, SCADA/HMI, and high-performance C++ or Rust services. The successful candidate will play a central role in defining the architecture, implementation standards, and operational reliability of mission-critical automation systems. Responsibilities Design, implement, and maintain PLC-based control systems for chemical processing equipment, test stands, and production systems. Develop and integrate SCADA/HMI systems for monitoring, control, alarming, and operational visibility. Build supporting services and control infrastructure in C++ or Rust for high-reliability and performance-critical components. Define and enforce modern software engineering practices, software architecture, coding standards, testing strategies, and operational best practices in PLC-based control systems. Work closely with hardware, electrical, and process engineering teams to integrate sensors, actuators, and field devices. Lead debugging, root cause analysis, and reliability improvements across the full automation stack. Basic Qualifications Bachelor’s degree or higher in Computer Engineering, Electrical Engineering, Computer Science, or a related field. 5+ years of experience developing industrial control systems or automation software. Strong, production-level experience in C++ or Rust. Hands-on experience with PLCs and industrial control platforms (e.g., Beckhoff/TwinCAT, Siemens, Rockwell, or equivalent). Experience with SCADA/HMI systems and industrial networking. Strong understanding of real-time systems, control loops, and hardware/software integration. Preferred Skills and Experience Background in safety-critical, high-reliability, or regulated industrial environments (e.g., chemical, energy, aerospace, robotics, semiconductor). Experience designing fault-tolerant, observable, and testable control systems. Experience with automated testing, simulation, or hardware-in-the-loop (HIL) test frameworks. Demonstrated technical leadership in setting engineering standards and mentoring other engineers. Additional Requirements Ability to work extended hours and weekends as necessary.
