Company Overview

Commonwealth Fusion Systems (CFS)

Cambridge, MA, United States

2018

Approximately 430 employees (source: zoominfo.com). Revenue figures vary, with reports indicating $211.3 million or $31.7 million, though as a pre-revenue fusion developer focused on R&D, these may reflect funding or operations rather than sales.

What They Do

Commonwealth Fusion Systems (CFS) is a pioneering private fusion energy company that specializes in tokamak-based magnetic confinement fusion. Founded as a spinout from MIT's Plasma Science and Fusion Center, CFS focuses on utilizing high-temperature superconducting magnets to achieve commercial net energy production (source: cfs.energy). The company has made significant strides in its technology, particularly with the development of compact fusion machines that leverage decades of tokamak science. Their flagship projects, SPARC and ARC, aim to demonstrate net energy gain and commercial viability in the coming years (source: cfs.energy).

Projects & Track Record

CFS is currently engaged in several groundbreaking projects, most notably the construction of SPARC, which is set to be the world's first net-energy fusion machine. Located at their Fusion Energy Campus in Devens, Massachusetts, SPARC aims to demonstrate net energy gain by the late 2020s (source: cfs.energy). Additionally, CFS is planning the ARC project, a 400 MW-class grid-scale tokamak power plant designed for commercial deployment in the early 2030s. These projects are underpinned by significant technological advancements, including the successful testing of the central solenoid magnet module (CSMC) in November 2024, which confirmed the manufacturability of critical components for SPARC (source: zoominfo.com).

Recent Developments

In the past two years, CFS has made remarkable progress, including the opening of its Devens Fusion Energy Campus on February 10, 2023, which was attended by notable figures such as U.S. Secretary of Energy Jennifer Granholm (source: cfs.energy). The company has also secured substantial funding, raising $863 million in August 2024, building on a previous $1.8 billion round in May 2023, bringing total funding to over $2 billion (source: wbjournal.com). Furthermore, CFS announced its first commercial power plant site in Chesterfield County, Virginia, which will be independently financed and operated, with plans for grid connection in the early 2030s (source: zoominfo.com).

Working There

CFS offers a range of roles across various disciplines, including fusion science, engineering, manufacturing, and materials science. The majority of their workforce is based at the Devens campus, which has grown to over 430 employees (source: cfs.energy). The company culture emphasizes rapid execution and transparency, attracting top talent from the fusion and manufacturing sectors. Key executives include Co-Founder and CEO Bob Mumgaard, along with other leaders in operations and science, indicating a strong demand for expertise in tough tech and physics (source: nasdaqprivatemarket.com). While specific benefits are not detailed, the scale-up and investor backing suggest competitive packages for high-caliber roles in a mission-driven environment (source: cfs.energy).

Job Description

CFS confronts exciting but significant challenges associated with the supply chain for ARC and other new products and projects. Key challenges for ARC include: (a) producing a design that leads to a very cost competitive and producible (deployable) product (b) managing high levels of technical uncertainty and (c) an expensive and operationally difficult path to begin building ARC power plants.

The Staff Supplier Integration Manager (SSIM) will create and execute global supply chain strategies fully integrated with CFS design teams and in close partnership with other functions including R&D, business and corporate development, Open Innovation, and government affairs. This strategy development will include focused and highly technical efforts to improve and simplify CFS designs with practical knowledge of supply chain capabilities, focused on major improvements to product cost and other key metrics. It will require deep, continuous, and insightful research into new technologies, evolving market conditions, and other key trends.

The SSIM will also conduct global, creative and systematic supplier searches, and build and manage complex, senior-level supplier relationships. Finally, the SSIM will lead negotiation of long-term, high-value agreements that will be pivotal to CFS' ability to build and deploy key products such as ARC.

The SSIM must be an established expert in technical sourcing, able to speak the languages of plasma physicists, engineers and material scientists. The SSIM must be experienced and comfortable in uncertain, unstructured, low Technology Readiness Level (TRL) environments, while exercising curiosity and creativity to identify and understand new trends and technologies. The SSIM should be capable of serving as the senior face of CFS to supplier executives and other external audiences, during difficult negotiations and other interactions. Internally, the SSIM should be able to speak directly to the Executive Leadership Team about how design and technical decisions translate into the supply of hardware, including associated cost, risk, etc. and should understand how to marshal internal resources and consensus in support of project objectives.
