Job description

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 mssion 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 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, Skunkworks-style projects, we encourage you to reach out to join our team.
We're hiring engineers across three focus areas:
Backend engineers will build high-performance services and APIs that coordinate control systems, manage state across distributed hardware, and expose interfaces for monitoring and operations.
Distributed systems engineers will architect fault-tolerant coordination systems, real-time data pipelines processing high-throughput sensor telemetry, and the infrastructure that keeps critical systems running reliably at scale.
Tooling engineers will develop the developer platforms, CI/CD systems, observability tools, and deployment infrastructure that let our team iterate rapidly and safely in a production environment where mistakes have physical consequences.
Responsibilities
  • Design and implement high-performance, production-grade software systems in C++ and Python, with a strong focus on reliability and maintainability
  • Architect complex solutions from the ground up, making principled decisions around system design, performance trade-offs, and technology selection
  • Lead technical design reviews and code reviews, setting and enforcing engineering best practices across the team
  • Build and maintain automated testing and CI/CD pipelines to ensure software quality at scale
  • Mentor junior and mid-level engineers while driving independent progress on complex, ambiguous technical problems

Basic Qualifications
  • Bachelor's degree in Computer Science, Engineering, or equivalent, with 5+ years of professional software engineering experience
  • Deep proficiency in C++ and/or Python, including language internals, performance characteristics, and idiomatic usage
  • Strong understanding of Linux internals - process management, memory models, I/O, and system calls - and how they influence software design and performance
  • Strong CS fundamentals - algorithms, data structures, concurrency, and system design
  • Demonstrated ownership of large, production-grade systems with evidence of exceptional technical ability

Preferred Skills and Experience
  • Experience with distributed systems, observability tooling, and infrastructure as code
  • Proficiency in Python ecosystems for data pipelines, automation, or backend services
  • Experience with C++ performance optimization, profiling, and low-level systems programming
  • Experience with Linux system programming, including threading models, IPC, real-time process management, and low-level kernel interfaces
  • Comfort across the full software development lifecycle, from design through deployment

Additional Requirements
  • Ability to work extended hours and weekends as necessary.
