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 operate in small, confined spaces and unusual locations, and work on platforms approximately 25 feet high.
  • Commitment to safety when working around industrial hazards including heat, cold, noise, fumes, strong magnets, lead, high voltage, and cryogenics.
  • Willingness to travel or occasionally work nights, weekends, or on-call.

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, including fiber passthrough flanges and enclosures.
  • Install composite or polymer wrappings for fibers and their enclosures.
  • Train other technicians in proper installation, splicing, routing, and measurement procedures as needed.
  • Improve safety protocols for laser and fiber-optic handling.
  • Fulfill manufacturing and research and development fiber needs.
  • Ensure functional operation and preventive maintenance of equipment and support continuous improvement.
  • Coordinate closely with Operations, Maintenance, Quality, and other departments to meet 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 environments with limited space or requiring unusual positions.
  • Fiber coating removal, fiber recoating, specialty fiber splicing, and fiber proof-testing skills.
  • Measurement and analysis techniques using optical tools and equipment such as interrogators, optical multiplexers, optical switches, and fault locators.
  • Knowledge of optics-sensing techniques and optical attenuation and insertion-loss mechanisms.
  • Basic Materials Science knowledge.

About the Company

Commonwealth Fusion Systems

Develops high-temperature superconducting fusion magnets

Commonwealth Fusion Systems builds fusion energy systems that aim to provide clean, affordable power. It designs tokamaks using high-temperature superconducting magnets to make smaller, less expensive machines. Its flagship SPARC is intended to produce net energy, with ARC envisioned as the first commercial fusion power plant. The company collaborates with MIT and focuses on a data-driven, mission-focused path to scalable fusion energy for large energy users.
