Job Description

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 nearly $3 billion in capital, making us the largest and leading private fusion company in the world.

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 Senior Techno-economic Analyst

For fusion power plants to be successful they must be economically competitive with other power generation technologies. The techno-economic analyst is responsible for developing models critical to evaluating fusion power plants' financial viability and commercial desirability. The candidate will work closely with internal CFS team members to create and evolve economic models, run sensitivity analysis, identify opportunities for improvement and provide input to design, engineering, and R&D on impacts. This role will serve an important function within the business development team supporting communicating the benefits of fusion energy to customers and key stakeholders.

What you'll do

  • Deliver:
    • Continue the development of techno-economic modeling at CFS to characterize the future costs and benefits of ARC, the world's first commercial fusion power plant
    • Incorporate expectations for learning and experience benefits as the company develops additional power plants
    • Establish and maintain company best practices and lessons learned related to analytical methods and models. Systematically work to improve models and analysis over time
    • Develop and assess ARC pricing and go to market approaches, including alternative applications of ARC beyond electricity
    • Track and maintain current assessment of ARC competitiveness compared to other energy solutions
    • Model the economic impact of ARC power plants for communities, regions, and states
    • Support individual project level analysis, including regional and local specifics, financing structures, and incentives
    • Expand economic modeling to target foreign markets to help inform go-to-market strategies
    • Work closely with the Scientific Software team to maintain the modeling tools and their underlying assumptions over time
    • Collaborate closely with Research and Development (R&D), Engineering, Manufacturing, Scientific Software, System Engineers, Finance, Business Development, and external stakeholders to collect primary data, populate techno-economic models, productionalize the model, and validate model fidelity
    • Provide support for non-power plant business functions and other duties as assigned

  • Strategize:
    • Work closely with procurement to refine estimates for costs for the power plant and associated systems
    • Identify key areas of risk, uncertainty, and variability within models and develop mitigation strategies with the business to alleviate where possible
    • Serve as a feedback loop to the R&D and engineering organizations to understand the key levers to continuously drive down ARC costs and LCOE
    • Synthesize quantitative results to provide insight into potential future technology research and development opportunities and design decisions
  • Problem Solve:
    • Apply quantitative and qualitative research, case studies, literature reviews, and learnings from internal and external subject matter experts to identify key variables and sensitivities important to determining the costs and value of ARC
    • Model the first-of-a-kind and future generations of fusion power plants under a wide range of development and deployment scenarios
    • Support the evaluation of new R&D opportunities, Open Innovation pathways, technology advancement, and market opportunities
    • Respectfully raise concerns, providing a sound rationale or data to support perspectives
    • Support potential customers, sponsors, partners, and investors in diligence processes
