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 software engineer, you will own and evolve the software infrastructure that supports hardware testing and system validation. This role includes developing and maintaining software for our Hardware-in-the-Loop (HITL) testbeds, automating Acceptance Test Procedures (ATP), and building robust tools that enable fast, reliable testing across engineering workflows. In addition, you will lead the development and management of our telemetry systems for development environments, ensuring high observability, performance monitoring, and data accessibility across teams. 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.

Responsibilities

• Design and implement modular, reusable automation software—primarily in Python—to support manufacturing and engineering design verification.
• Write automation software for test article, test equipment, instrumentation, and production documentation systems.
• Enable test execution across diverse environments, including hardware-in-the-loop (HITL) and virtualized simulations.
• Create algorithms to analyze complex test data and verify compliance with acceptance criteria.
• Develop tools that improve the frequency, reliability, and automation of software deployment, test execution, and data analysis within a continuous integration and release environment.

Basic Qualifications

• Bachelor’s degree in computer science, engineering, math, or STEM discipline.
• 3+ years of software development expertise in C, C++, or Python; or full stack software development.
• Evidence of exceptional ability (prior projects, portfolio of work, completed products, etc).
• Strong understanding of engineering fundamentals.

Preferred Skills and Experience

• Extensive knowledge of Linux and Windows operating systems.
• Experience with configuration management and version control software.
• Experience deploying and maintaining build toolchains, test software infrastructure, and telemetry systems.
• Experience automating processes and testing to improve manufacturing yields and reduce production time.
• Knowledge with a range of digital and analog interfaces including GPIB, USB, VISA, TCP/IP, VLAN, CAN bus, SPI, I2C, Modbus, analog-to-digital conversion.
• Strong skills in troubleshooting, debugging, performance optimization, and unit testing.
• Solid fundamental knowledge of networks, electronics, math, and physics.
• 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.
