Software Engineer, Systems Engineer

General Matter is enriching uranium in America.

Our mission is to restore our country’s ability to make nuclear fuel. Our fuel will help power AI, manufacturing, and other critical industries. It will power our next generation of reactors. Ultimately, it will power our national ambitions.

We were incubated by Founders Fund, like Anduril and Palantir before us, and we are backed by top tier investors.

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.

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.

If you seek high-impact and are excited by fast-paced, intense, Skunk works-style projects, we encourage you to reach out to join our team.

• Design and implement fault-tolerant, safety-critical control software for regulated manufacturing environments.
• Architect and maintain deterministic, real-time systems that meet strict reliability and regulatory compliance requirements.
• Integrate software with sensors, actuators, and industrial control systems (PLCs, SCADA, fieldbus protocols).
• Perform hazard, risk, and safety analyses (e.g., FMEA, FTA, HAZOP) and implement mitigations in software architecture and state machines.
• Develop validation and verification pipelines, including automated and formal methods testing, to ensure compliance with industry standards.
• Collaborate with hardware, controls, and quality teams to ensure system-level safety and regulatory compliance.
• Contribute to secure build, deployment, and configuration management processes with traceability across the full software lifecycle.
• Participate in regulatory audits and documentation, supporting certification efforts with complete and accurate records.

• Bachelor’s degree in Computer Science, Electrical/Computer Engineering, or equivalent STEM discipline, and 5+ years of professional experience in safety-critical or real-time systems software development.
• Proficiency in C/C++ and/or Rust running on Linux.
• Demonstrated ability to deliver production software that meets formal safety or regulatory standards (e.g., 10 CFR, NQA-1, IEC 61508, ISO 13849, DO-178C, ISO 26262, or similar).
• Ability to apply first-principles engineering and structured trade-offs when faced with incomplete or uncertain information.
• Evidence of exceptional technical ability (published work, prior production-grade safety systems, or similar).
• Experience with formal testing, code review, and verification frameworks for high-integrity software.

• Experience with modern software infrastructure including compute abstraction, programmable networks, distributed storage systems, observability tools, and infrastructure as code techniques.
• Direct experience with factory automation, process control, or mission-critical industrial systems.
• Knowledge of functional safety design patterns and certification processes in regulated industries (nuclear, aerospace, medical devices, automotive).
• Experience with PLC integration, fieldbus/industrial Ethernet protocols (e.g., Ether
  
  CAT, PROFINET, Modbus).
• Familiarity with signal processing and real-time data acquisition pipelines.
• Experience with model-based design, formal verification tools, or static analysis in safety-critical domains.
• UI/UX collaboration experience for operator interfaces, alarms, and human-machine interaction, with a focus on clarity and safety rather than aesthetics.
• Ability to debug and validate software/hardware interactions using oscilloscopes, logic analyzers, and other diagnostic equipment.
• Strong written and verbal communication skills,…
