Commonwealth Fusion Systems

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 seekers are encouraged to monitor their careers page for openings related to SPARC and ARC advancements.

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 we're 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.

What you'll do

  • Lead a team of 2-3 cleaning technicians. Assign daily tasks, manage throughput, and maintain a flexible schedule to meet shifting production demands. Act as the onsite trainer to educate team and management on chemical safety, contamination control, and proper hardware handling techniques
  • Partner closely with dedicated Material and inventory Coordinators to ensure tracking, batch control, and material movements are seamlessly logged in the ERP system
  • Author Standard Operating Procedures (SOPs) for various cleaning modalities, including immersion/baths for small hardware and manual wipe-down protocols for oversized metal components. Assist in the selection, commissioning, and validation of specialized cleaning equipment (e.g., ultrasonic baths, parts washers, chemical stations, or specialized filtration/ventilation systems)
  • Research, define, and implement component-cleaning standards, validation methods, and workflow layouts based on industry's best practices for industrial metal parts
  • Obey and enforce all CFS Safety guidelines. Manage the safe handling, storage, and disposal of cleaning solvents, chemical agents, and hazardous waste in compliance with SDS and CFS plans. Maintain a highly organized, clean, and audit-ready clean area

What we're looking for

  • High School Diploma or equivalent
  • Technical certifications in industrial chemistry, materials science, or manufacturing technology preferred
  • 3-5 years of experience directly executing and managing industrial parts-cleaning operations within a manufacturing, aerospace, automotive, or precision-machining environment
  • Proven team leadership or supervisory experience; must have a record of successfully assigning tasks, managing team throughput, and driving accountability on a manufacturing floor
  • Deep knowledge of a variety of cleaning methodologies (e.g., solvent cleaning, aqueous degreasing, ultrasonic cleaning, acid/alkaline baths, and precision manual wiping)
  • Proven experience handling metals of various shapes and scales, understanding how surface finishes, oils, and particulate matter impact downstream assembly
  • Demonstrated experience establishing a line, setting up cleaning work-cells, or implementing new manufacturing procedures from scratch
  • Functional understanding of ERP systems (Odoo, SAP, Oracle) and how material tracking impacts production

Bonus Points For

  • Bachelor's Degree
  • Strong technical training skills; comfortable explaining chemical and physical cleaning constraints to non-technical team members
  • Strong computer skills with MS Office or G-Suite applications (Excel, Docs) for drafting procedural checklists
  • Experience operating material handling equipment (forklifts, pallet jacks) is a plus

Must-have requirements

  • Ability to occasionally lift up to 50 lbs
  • Perform activities such as stopping, climbing, typing, standing, and sitting for extended periods of time
  • Dedication to safety to mitigate hazards that may include heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, and cryogenics

$40 - $50 an hour

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.
