About Marathon Fusion

Since our founding in 2023, we've developed fuel cycle technologies to deliver fusion energy more quickly with better economics. Marathon Fusion was founded by Adam Rutkowski, previously a Propulsion Engineer at SpaceX and PhD candidate in Plasma Physics at Princeton University, and Kyle Schiller, previously a Fellow in science policy at Schmidt Futures. We believed then, and now more than ever, that fusion is humanity's best pathway to abundant, clean and reliable energy.

We've secured over $10m in funding from the US Department of Energy and leading investors including 1517 Fund and Strong Atomics. We have letters of intent from leading fusion companies including Helion Energy, Commonwealth Fusion Systems, and Thea Energy.

We've built plasma centrifuges for isotope separation, superpermeable pumps for rapid fuel recycling in fusion power plants. We're on a quest to commercialize alchemy, accelerate the deployment of fusion energy, and open a new frontier in scientific discovery.

Culture at Marathon Fusion

We are a startup environment characterized by a need for focus, adaptability and prioritization in a shifting landscape. Thriving in this environment requires excellent proactive communication across roles and backgrounds, the ability to build and maintain trust between team members, and the willingness to learn and develop new skills on the job. We place particularly high weight on each team member's ability to be self-directed.

Role Description

We are seeking an Electrical Engineer with hands-on experience in high-power and control systems. You’ll work closely with mechanical engineers, physicists, and technicians, to prototype, test, and deploy solutions in the pursuit of advancing the development of the fusion fuel cycle and stable isotope production.

This role requires a blend of practical engineering skills and systems level thinking. You will play a pivotal role in integrating and supporting power systems, developing safe and robust control architectures, and standardizing data collection across experimental test stands.

What You’ll Do

• Collaborate closely with mechanical engineers and technicians to rapidly prototype and test experimental systems
• Design, integrate, and support high-power and pulsed power systems with a focus on safety, reliability, and performance
• Develop, standardize, and maintain data acquisition systems across multiple test setups
• Define, implement, and document control system architectures, including hardware selection, wiring diagrams, and functional logic
• Coordinate with panel shops or internal technicians to layout, build, and validate custom control panels
• Contribute to the safe design and operation of high-voltage, high-current equipment
• Support testing, troubleshooting, and commissioning of control systems and power electronics
