About Marathon Fusion

We are building the fuel cycle for fusion energy on climate-relevant timelines to accelerate the deployment of this critical energy resource. By working alongside universities, national labs and industry partners to commercialize critical technologies, we aim to ensure the safe and economic deployment of fusion energy at meaningful speed and scale.

Marathon is supported by some of the energy industry's leading investors, alongside the US Department of Energy’s ARPA-E and Breakthrough Energy.

About the Team

Kyle and Adam founded Marathon Fusion to remove roadblocks to fusion deployment and meet the demands of the burgeoning industry. Kyle comes from the policy world, previously reporting to the CIO of Schmidt Futures. Adam was a research engineer at Otherlab developing high efficiency heat pumps, worked on the DEMO-2 mission at SpaceX to return humans to the ISS, and received his MA from Princeton in Plasma Physics.

Our growing team includes

• 4 scientists (plasma physics, chemical engineering, materials science), including first author on landmark tritium processing papers

• 4 engineers (+6 incoming with offers signed) from SpaceX, Tesla, Stanford, Fermilab, Argonne and more

• Ops team (incl. ex-Head of Finance at Series B hard tech startup)

Research at Marathon Fusion

The research team is responsible for leading experimentation. You'll work closely with engineers to set priorities for test stand development, analyze data and review literature to further the performance of our devices, and proactively seek out ways to accelerate the R&D roadmap.

In this role, you'll have the opportunity to

• Design, build and operate cold plasma sources, vacuum systems and related equipment

• Craft technical roadmaps alongside our team, as well as external collaborators at partner universities and national labs

• Play a role in enabling the commercialization of fusion energy

Job Requirements

Our work requires a willingness to adapt to rapidly changing circumstances and shifting priorities, while keeping an eye on the long-term goals that ultimately drive success. Navigating this environment necessitates effective communication across roles and backgrounds, a high degree of trust between team members, and the willingness to learn and develop new skills on the job. We place particular weight on a team member's ability to be self-directed and proactive.

The ideal candidate will meet most of these requirements:

• An undergraduate degree in physics

• Experience in a lab setting doing hands-on experimentation

• Proficiency at data analysis and presentation

• Excellent written and oral communication skills

• Excited to think deeply and at a systems-level
