About the company:

Commonwealth Fusion Systems (CFS) is on a mission to deliver clean fusion energy to the planet fast enough to matter for humanity’s biggest challenges.

It’s urgent. The gap between the energy we need and the energy we have is widening every day. Fusion is a critical part of the energy transition away from fossil fuels, a new chapter for the world’s energy supply.

We’re committing to delivering fusion power plants and a full-fledged fusion energy industry as we’ve delivered on other promises. Like the world’s strongest high-temperature superconducting magnet, the game-changing technology that’s making commercial fusion energy a reality.

We’ve raised over $2 billion in capital — more than any other fusion energy company — and attracted top talent to design, build, and deliver commercial fusion power plants. And we’re working with policymakers and suppliers to make fusion energy available globally.

As we push toward the fusion-energy future, we’ll keep setting and meeting milestones, sharing and validating our progress, and encouraging others to do the same.

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 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-economics 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.

At CFS, we excel in fast-paced environments, driven by our values of integrity, execution, impact, and self-critique. As we grow, we’re eager to bring on mission-driven folks who offer diverse perspectives and fresh ways to tackle challenges.

We value diversity deeply and are proud to be an equal opportunity employer by choice. We consider all qualified applicants equally, regardless of race, color, national origin, ancestry, citizenship status, protected veteran status, religion, physical or mental disability, marital status, sex, sexual orientation, gender identity or expression, age, or any other basis protected by law.

This role requires compliance with U.S. laws concerning the export of controlled or protected technologies or information (collectively, “Export Control Laws"). Any offer of employment will be contingent on the need for compliance with such Export Control Laws.

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

Prepare briefing materials, write and publish research results in internal technical reports and public facing presentations, including collaborations with key external partners

Support Investor Relations, Business Development, Corporate Finance, and Engineering teams as needed, and on-demand with queries and reports

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

Support management in developing scope, budget, and schedule for new projects based on matching expertise and capabilities to research needs and project opportunities
