Careers at Commonwealth Fusion Systems


Last updated on 2025-03-27 | Report an issue

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 Manager, Diagnostic Support Equipment

The SPARC Diagnostics Team is divided into multiple teams to facilitate the deployment of hardware, the development and management of staff, as well as to establish a point of decision making between the Diagnostic Team Lead and the individual system leads in cases where there are zero-sum trade-offs and multi-system design optimizations that need to be made. Three of these DIAG teams are instrumentation teams focused on the delivery of hardware that will be used in day-to-day SPARC operations. This position focuses on a fourth team which is responsible for delivering equipment that provides functional support, but does not participate in the transformation of the signal from plasma to bits. This support equipment is highly interface constrained and helps to provide solutions between instrumentation systems within DIAG or between DIAG and other structural members (e.g. the building or vacuum vessels). When viewed from outside of DIAG, the distinction between support equipment and instrumentation effectively vanishes, but internal to DIAG this breakdown helps to facilitate speed and quality.

The Manager of the Diagnostic Support Equipment (DSE) team is expected to provide team leadership as well as carry out responsibilities of an individual contributor on an as needed basis to help facilitate the delivery of DSE hardware. The role of the Manager will evolve over the course of the SPARC project as systems move from design to operation, but is envisioned to have the Primary Responsibilities listed below. Candidates will work as part of an integrated team that includes many interfacing systems as well as science staff from outside of CFS. Experience working on tokamak or fusion plasma diagnostics is not required and CFS welcomes applications from non-tokamak or non-fusion backgrounds that can help deliver SPARC's diagnostic capabilities.

What you'll do

  • Proactively identify where challenges faced by one or more instrumentation teams can be best solved by creating or modifying a common sub-system
  • Work with teams inside of CFS (SysEng, Safety, etc.) to path-find how to verify the designs of Diagnostic Support Equipment systems that are unique or first-of-a-kind for the Tokamak Hall or Diagnostic Labs
  • Ensure the completion of the design of Diagnostic Support Equipment and communicate risks and needs to the Diagnostic Team Lead
  • Shepherd the completion of PASY/SASY for DSE systems, communicating safety concerns, risks and needs to the Diagnostic Team
  • Provide line-management support to the Diagnostic Support Equipment Team, which presently consists of the system leads and dedicated engineers and designers
  • Assist system leads in maintaining communication and well-defined interfaces with non-DSE systems, both inside and outside of DIAG
  • Identify where the overall complexity in SPARC Diagnostics could be reduced through shared design solutions, and act as decision maker for 'Tier-2' changes relevant to support equipment
  • Assist the Diagnostic Team Lead in managing scope, budget and schedule risk, including approving purchase orders/engineering orders within agreed upon limits
  • Ensure the planning and delivery of DSE components to ensure instrumentation systems to achieve Commissioning and Operations milestones on-schedule
  • Will supervise a team of ~10 engineers and scientists

What we're looking for

  • Bachelor's degree in a relevant engineering field (mechanical, aerospace, civil or nuclear), with advanced degrees improving the job execution
  • Experience in design, fabrication and installation of similar equipment for a project or facility: equipment platforms, cabling/piping, shielding
  • Prior experience with line management is encouraged, but candidates at a minimum must demonstrate leadership experience, e.g. leading a team to accomplish a goal/mission or to deliver a product
  • Ability to direct staff accomplishing complex tasks where your full understanding may not be possible.
  • Responsibly managing a budget
  • Be able to maintain productivity while also experiencing high-levels of context switching

Must-have requirements

  • Ability to occasionally lift up to 50 lbs
  • Perform activities such as typing, standing, or sitting for extended periods of time
  • Willingness to travel or work required nights/weekends/on-call occasionally
  • Work in a facility that contains industrial hazards including heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, high current, pressure systems, and cryogenics

$150,000 - $225,000 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:

  • Competitive compensation with equity
  • 12.5 Company-wide Holidays
  • Flexible vacation days
  • 10 sick days
  • Generous parental leave policy
  • Health, dental, and vision insurance
  • 401(k) with employer matching
  • Professional growth opportunities
  • Team-building activities
