Commonwealth Fusion Systems (CFS) is on a mission to deliver clean fusion energy to the planet fast enough to matter for humanity’s biggest challenges.
It’s urgent. The gap between the energy we need and the energy we have is widening every day. Fusion is a critical part of the energy transition away from fossil fuels, a new chapter for the world’s energy supply.
We’re committing to delivering fusion power plants and a full-fledged fusion energy industry as we’ve delivered on other promises. Like the world’s strongest high-temperature superconducting magnet, the game-changing technology that’s making commercial fusion energy a reality.
We’ve raised over $2 billion in capital — more than any other fusion energy company — and attracted top talent to design, build, and deliver commercial fusion power plants. And we’re working with policymakers and suppliers to make fusion energy available globally.
As we push toward the fusion-energy future, we’ll keep setting and meeting milestones, sharing and validating our progress, and encouraging others to do the same.
About Commonwealth Fusion Systems:
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 Fiber Optic Specialist
The Fiber Optic Specialist on the SPARC Assembly Team is an exciting and evolving role with a responsibility for performing all aspects of optical fiber work such as fiber handling, splicing, testing, and incorporation of fibers into complex design features in the process of assembling our fusion machine. The technician will ensure functional installation, health, and operation of the fibers, as well as look for opportunities for continuous improvement. Responsibilities include close cooperation with Operations, Engineering, Quality, and other departments to ensure goals and objectives are met. This role will lead the way to making Earth sustainable for the future to come.
This work is conducted within a multi-disciplinary team of technicians and engineers. Participation and clear, concise communication while working with the team is crucial.
This position will cover the first shift - 7:00 am to 3:00 pm, with opportunities for overtime in certain periods related to schedule needs.
#LI-Onsite
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.

This role requires compliance with U.S. laws concerning the export of controlled or protected technologies or information (collectively, “Export Control Laws"). Any offer of employment will be contingent on the need for compliance with such Export Control Laws.
What you'll do:
Conduct the handling, routing, splicing, testing, and potential repair of 1000’s of fibers throughout the SPARC fusion machine
Perform mechanical integration of small assemblies adjacent or in conjunction with the fiber work, such as passthrough flanges and enclosures for the fibers
Install composite or polymer wrappings for the fibers and their enclosures
Train other technicians as needed in the proper installation, splicing, routing, and measurement procedures
Improve safety protocols for laser and fiber optic handling
Fulfill manufacturing and R&D fiber needs
What we’re looking for:
4+ years experience in fiber optics field applications
Experience with taking attenuation, insertion loss, and spectral analysis measurements using various measurement equipment (such as OTDR, OSA, OBR, power meter, etc.)
Must have experience fiber handling in a lab setting with known standards
Bonus points for:
7+ years experience in fiber optics field applications
Experience in utilizing distributed sensing arrays
Experience with polyimide and a variety of coated fibers
At least 1 year experience in teaching and/or training fiber splicing techniques and cable assemblies
Experienced with designing, building, and testing fiber cable assemblies, particularly in cryogen and vacuum conditions
Experience performing fiber optic work in environments with limited space or requiring odd positions.
Skills:
Fiber coating removal
Fiber re-coating
Specialty fiber splicing
Fiber proof-testing
Measurement and analysis techniques with optical tools and equipment such as interrogators, optical multiplexers, optical switches, fault locators, OTDR, etc.
Knowledgeable about various optics sensing techniques and optical attenuation/insertion loss mechanisms
Basic Materials Science knowledge
Good communication skills
Good attention to detail
Must-have Requirements:
Ability to occasionally lift up to 50 lbs
Perform activities:
Stooping, typing, standing, or sitting for extended periods of time
May need to operate in small confined places in odd locations
Work locations could include being on platforms around 25 feet high
Dedication to safety to mitigate industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, and cryogenics
Willingness to travel or work required nights/weekends/on-call occasionally
