Fiber Optic Specialist

Commonwealth Fusion Systems (CFS) has the fastest, lowest cost path to commercial fusion energy.

CFS collaborates with MIT to leverage decades of research combined with groundbreaking new high-temperature superconducting (HTS) magnet technology. HTS magnets will enable compact fusion power plants that can be constructed faster and at lower cost. Our mission is to deploy these power plants to meet global decarbonization goals as fast as possible. To that end, CFS has assembled a team of leaders in tough tech, fusion science, and manufacturing with a track record of rapid execution. Supported by the world's leading investors, CFS is uniquely positioned to deliver limitless, clean, fusion power to combat climate change. To implement this plan, we are looking to add dedicated people to the team who treat people well, improve our work by adding multifaceted perspectives and new ways of solving problems, have achieved outstanding results through a range of pursuits, and have skills and experience related to this role.

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.

This team member will:

• Work with engineering to develop splicing/routing techniques of >1000 fibers to minimize complexity, time, and cost
• Train manufacturing technicians 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

The ideal candidate will have most, if not all, of these requirements:

• 4+ years experience in fiber optics field applications, 7+ years' experience preferred
• Experience in utilizing distributed sensing arrays (FBG preferred)
• 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

Additional experience and/or qualifications:

• Experience in utilizing distributed sensing arrays (FBG preferred)
• Experience with polyimide 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
• Skills:
• **Fiber coating removal
• **Fiber re-coating
• **Specialty fiber splicing
• **Fiber proof-testing
• Measurement techniques using 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
• Ability to occasionally lift up to 50 lbs
• Perform activities such as stooping, typing, standing, or sitting for extended periods of time, may need to operate in small confined places in odd locations
• 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
• #LI-Onsite
