About This Job


About Commonwealth Fusion Systems:

Commonwealth Fusion Systems is on a mission to deliver the urgent transition to fusion energy.

Combining decades of research, top talent and new technologies, we’re designing and building commercially viable fusion power plants. And working with policymakers and suppliers to build the energy industry of the future.

We’re in the best position to make it happen. Since 2018, we’ve raised over $2 billion in capital – more than any other fusion energy company in the U.S.

Now we’re looking for more thinkers, doers, builders, and makers to join us. People who’ll bring new perspectives, solve tough problems, and thrive as part of a team.

If that’s you and this role fits, we want to hear from you. Join the power movement as a Real-Time Software Engineer

The Real-Time Software Engineer will be responsible for the design, debug, and implementation of the software and controls of advanced R&D equipment and complex machinery.

As a member of the controls software team you will be a hands-on technical contributor, a champion of writing excellent quality, production-ready code for mission-critical real-time systems. You will collect functional requirements from customers and produce software solutions to meet these requirements.

You will work with simulation and test engineers to integrate your software into software testbeds, hardware testbeds, and the production tools.

What you'll do:

Work within a multi-disciplinary and proven team of top scientists and engineers

Specify, write, and test control software for advanced production equipment
Own the specification, design, testing, and implementation of key systems such as interlocks, sensors and actuators, higher level tool control and user interface programming
Work closely with process team to outline interfaces and requirements for equipment and software operation for equipment control
Engage with mechanical and electrical engineers on concepts, designs, and test plans by providing data acquisition and controls as needed
Work with external software contractors to develop the control systems for internal production tools (Define requirements, manage priorities, drive testing and implementation plans)


What we’re looking for:

A bachelor’s degree in a relevant engineering field (e.g., mechatronics, software)

3+ years of experience as software engineer on complex mechanical systems * - for example: design, construction, and operation of controls for industrial, large-scale equipment

Working knowledge of Python, C++, C and other high level languages along with modern tools like github and CI/CD release management
Experience with developing control loops, physics-based modeling, or simulation platforms
High self-motivation and drive to execute quickly with excellent troubleshooting and problem-solving skills


Bonus points for:

Experience with GUI development using tools such as Ignition
Knowledge of fieldbus systems (like EtherCAT)
Networking basics (IP/UDP/TCP)
Real-time system software development experience
Familiarity with Linux environments
Exposure to safety interlock systems or standards like NFPA 79 and SEMI S2
Design for manufacturability, serviceability, and simplicity over complexity


Must-have Requirements:

Ability to occasionally lift up to 50 lbs
Perform activities such as stooping, climbing, standing, or sitting for extended periods of time
Dedication to safety to mitigate industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, and cryogenics
Willingness to travel or work required nights/weekends/on-call occasionally
