About the Job

Requirements

At least 4 years of experience in fiber optics field applications.
Experience taking attenuation, insertion loss, and spectral analysis measurements using measurement equipment such as optical time-domain reflectometers, optical spectrum analyzers, optical backscatter reflectometers, and power meters.
Experience handling fiber in a laboratory setting using established standards.
Ability to occasionally lift up to 50 pounds.
Ability to stoop, type, stand, or sit for extended periods.
Ability to work in small confined spaces and awkward locations, and on platforms around 25 feet high.
Dedication to safety when working around industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead, high voltage, and cryogenics.
Willingness to travel or occasionally work nights, weekends, or on call.
Knowledge of fiber coating removal and recoating, specialty fiber splicing, and fiber proof-testing.
Knowledge of measurement and analysis techniques using optical tools and equipment, including interrogators, optical multiplexers, optical switches, fault locators, and optical time-domain reflectometers.
Knowledge of optical sensing techniques and optical attenuation and insertion-loss mechanisms.
Basic materials science knowledge.

Responsibilities

Handle, route, splice, test, and potentially repair thousands of fibers throughout the SPARC fusion machine.
Perform mechanical integration of small assemblies adjacent to or in conjunction with fiber work, such as fiber passthrough flanges and enclosures.
Install composite or polymer wrappings for fibers and their enclosures.
Train other technicians as needed in proper fiber installation, splicing, routing, and measurement procedures.
Improve safety protocols for laser and fiber-optic handling.
Fulfill fiber needs for manufacturing and research and development.
Support research and development and production staff with optical fiber work, including splicing, testing, and incorporating fibers into complex design features while minimizing fiber damage and attenuation throughout its lifetime.
Ensure functional operation and preventive maintenance of equipment, and contribute to continuous improvement.
Coordinate with Operations, Maintenance, Quality, and other departments to support goals and objectives.

Desired Qualifications

At least 7 years of experience in fiber optics field applications.
Experience using distributed sensing arrays.
Experience with polyimide and a variety of coated fibers.
At least 1 year of experience teaching or training fiber-splicing techniques and cable assemblies.
Experience designing, building, and testing fiber cable assemblies, particularly in cryogenic and vacuum conditions.
Experience performing fiber-optic work in limited-space environments or awkward positions.

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, suppliers, and many others to build the energy industry of the future.

We’re in the best position to make it happen. Since 2018, we’ve raised $4 billion of capital, making us the largest and leading 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 Applications Technician is an exciting and evolving role with a responsibility for assisting R&D and production staff with all aspects of optical fiber work such as fiber splicing, testing, and incorporation of fibers into complex design features while minimizing damage and attenuation to the fiber throughout its lifetime. The technician will ensure functional operation and preventative maintenance of equipment as well as continuous improvement. Responsibilities include close cooperation with Operations, Maintenance, 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.

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
