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.

Join the power movement as a Quality Control Manager

We are looking for a Quality Control Manager to champion operational excellence within our manufacturing ecosystem. By leading a multidisciplinary team of quality experts, you will oversee the seamless integration of inspection protocols and assembly validation, ensuring every component meets the exacting requirements necessary to power the future.

What you'll do

  • Direct an elite team of metrology engineers and QC inspectors, optimizing daily resource allocation and providing real-time status reporting on critical-path inspections
  • Mentor and upskill technicians and inspectors, fostering a culture of technical excellence and continuous professional development
  • Oversee the Quality Inspection Lab, ensuring the precision of metrology equipment and the rigorous calibration of all mission-critical tools
  • Interpret complex blueprints and engineering requirements to ensure 100% adherence to technical specifications
  • Review and certify material test reports (MTRs) and inspection data from global suppliers to ensure the integrity of the CFS supply chain
  • Engineer robust inspection procedures for incoming materials and in-process manufacturing to validate compliance with CFS's exacting assembly standards
  • Lead the selection and implementation of advanced portable metrology and CMM technologies to keep pace with evolving hardware designs
  • Bridge the gap between Design, Quality, and Manufacturing Engineering to ensure that "design for manufacturability" translates into "flawless execution" on the shop floor
  • Champion a culture of organizational discipline by implementing 5S methodologies (Sort, Set in Order, Shine, Standardize, Sustain) across the QC Lab and shop floor to optimize inspection flow, enhance technician safety, and eliminate waste in the measurement process

What we're looking for

  • Bachelor's degree in Mechanical Engineering, Metallurgy, Materials Science, or a related technical field. (Equivalent experience in a high-rigor industry like Aerospace or Nuclear may be considered)
  • 7+ years of experience in a Quality Control or Manufacturing Engineering role, with at least 3 years in a direct supervisory or management capacity
  • Experience in "First-of-a-Kind" (FOAK) manufacturing, transitioning prototypes into scalable production environments
  • Proficient in interpretation and usage of ASME Y14.5 (Geometric Dimensioning and Tolerance)
  • Knowledge of ISO 9001:2015 quality management systems
  • Be able to set up, maintain, and use various inspection hand tools (calipers, micrometers, bore gages, rings & plug gages, profilometer, height gages, etc.)
  • The ability to translate complex technical non-conformances into actionable feedback for Design and Manufacturing engineers
  • A "startup" mentality-comfortable with ambiguity and capable of making high-stakes decisions in a rapidly evolving engineering landscape

Bonus points for

  • Demonstrate proficiency in advanced metrology, including fixed and portable CMM's (Faro/Romer arms) and laser tracking systems

Must-have requirements

  • Ability to lift up to 50 lbs occasionally
  • Perform activities such as standing, stooping, and sitting for extended periods of time
  • Dedication to safety to mitigate hazards that may include heat, cold, noise, fumes, strong magnets, lead, high voltage, and cryogenics
  • Willingness to occasionally travel or work required nights/weekends/on-call

$110,000 - $185,000 a year

Salary range for this full-time position + equity + benefits. The actual salary will depend on level, location, qualifications, and experience. The range displayed on each job posting reflects new hire salaries for the position across all US locations. Benefits include:
