How to apply for Head of Origination

About Commonwealth Fusion Systems (CFS)

Commonwealth Fusion Systems is building commercially viable fusion power plants, starting with the SPARC demonstration plant outside Boston and ARC power plants expected online in the early 2030s. Since 2018 it has raised $4 billion, making it the largest and leading fusion company in the world. This role is a chance to build the commercial side of a new energy industry from the ground up.

About the role

The Head of Origination leads customer and partnership strategy and deals for future ARC power plants. You own commercialization, market entry, and structured contracting. The work shapes who buys fusion power and on what terms before the first plant is online.

A typical day

A typical day likely involves meetings with potential customers, partners, or policymakers, plus internal work on deal structures and market entry plans. You would coordinate with technical, legal, and policy teams to turn early interest into signed agreements. The exact rhythm of the team is not described in the posting, so ask about it in the interview.

Who Commonwealth Fusion Systems (CFS) is looking for

• Has closed large, structured energy or infrastructure deals, such as power purchase agreements, joint ventures, or long-term offtake contracts.
• Can build a commercialization strategy from scratch for a product that does not yet exist on the market.
• Has worked with utilities, large corporate buyers, policymakers, or suppliers in the energy sector.
• Is comfortable with long sales cycles and technical uncertainty, and can engage customers before the first ARC plant is online.

Tips for this application

• Name specific deals you have originated or closed, including counterparty type, deal size, and structure (PPA, JV, offtake).
• Show you understand that ARC plants are expected online in the early 2030s, and explain how you would build a pipeline before then.
• Refer to SPARC and ARC by name in your materials to show you have read past the job description.
• Address structured contracting directly, since the role lists it as a core responsibility.
• Explain how your market entry experience maps to a first-of-a-kind product with no existing market.

What to cover in your cover letter

Your track record of originating and closing structured energy or infrastructure deals. Your approach to building market entry for a product that is not yet commercially available. How you would engage customers and partners years before the first ARC plant is online. Why fusion specifically, and why CFS rather than another energy company.

Research before applying

• Read CFS materials on SPARC and ARC, including timelines and expected plant capacity.
• Study the $4 billion raised since 2018 and who the investors are.
• Research how other first-of-a-kind energy technologies, such as advanced nuclear or offshore wind, built early customer pipelines.
• Check what CFS has said publicly about policymakers, suppliers, and building the energy industry of the future.

Likely interview topics

Based on the job description, expect questions about:

• Walk through a complex structured deal you originated, including how you found the counterparty and closed it.
• How would you build a customer pipeline for ARC power plants before they are online in the early 2030s?
• Which customer segments would you target first for fusion power, and why?
• How would you structure a contract when the product's cost and delivery timeline are still uncertain?
• How would you work with policymakers, suppliers, and regulators as part of a market entry strategy?

Common mistakes to avoid

• Treating this like a standard energy sales role. Fusion power is not yet commercially available, so the job is about building a market, not selling an existing product.
• Ignoring structured contracting. The role names it explicitly, so a resume without deal structuring experience is a weak fit.
• Being vague about deal history. Candidates who cannot name counterparties, deal sizes, and structures will not stand out.
