About Commonwealth Fusion Systems:
Key Responsibilities
- Partner with Fiber Optic Specialists and production teams to develop, standardize, and continuously improve fiber optic manufacturing processes
- Transition fiber optic products and processes from R&D and prototype builds into repeatable, scalable production
- Develop, implement, and qualify manufacturing processes for fiber optic cables and assemblies, balancing quality, optical performance, throughput, cost, and production rate
- Develop and optimize processes for fiber handling, routing, splicing, wrapping, jacketing, bonding, termination, and cable assembly as applicable
- Develop manufacturing processes and controls that prevent fiber damage, including excessive bending, pinching, tension, handling, routing, and other sources of optical or mechanical degradation
- Develop and optimize tooling, fixtures, equipment, and workstations to enable repeatable fiber optic manufacturing while protecting sensitive fiber and cable components
- Partner with Design Engineering to apply Design for Manufacturing (DFM) and Design for Assembly (DFA) principles and ensure product designs are manufacturable at production scale
- Establish manufacturing process parameters, acceptance criteria, inspection methods, and process controls for critical fiber optic processes
- Create and maintain manufacturing documentation, including work instructions, process flow diagrams, pFMEAs, standard operating procedures (SOPs), and process control plans
- Partner with Quality and Test Engineering to develop effective inspection and test methods for critical fiber optic requirements
- Use manufacturing and optical performance data to identify sources of variation, establish process capability, and improve first-pass yield, scrap, rework, cycle time, and throughput
- Troubleshoot manufacturing and quality issues using structured root-cause analysis, experiments, data analysis, and hands-on investigation
- Lead continuous improvement and RCCA projects that improve manufacturing yield, reduce fiber damage and scrap, and increase process robustness
- Provide hands-on technical support and training to Fiber Optic Specialists and production personnel on processes, tooling, equipment, work instructions, and best practices
- Support manufacturing capacity planning, equipment requirements, production readiness, and process scaling
- Ensure manufacturing processes meet applicable safety, quality, and production requirements
Requirements
- Bachelor's degree in Mechanical Engineering, Manufacturing Engineering, Industrial Engineering, Optical Engineering, or equivalent work experience
- 5+ years of manufacturing engineering experience, including experience developing or improving fiber optic, optical, cable assembly, precision assembly, or other technically sensitive manufacturing processes
- Experience working directly with fiber optic manufacturing, cable assembly, optical fiber handling, splicing, testing, or related precision processes
- Strong understanding of manufacturing process development, process control, troubleshooting, and continuous improvement
- Experience with Lean Manufacturing, Six Sigma, RCCA, DOE, SPC, process capability, or other structured problem-solving methodologies
- Strong analytical and problem-solving skills, with the ability to use manufacturing and test data to identify root causes and drive process improvements
- Excellent communication and interpersonal skills, with the ability to work effectively with engineers, Fiber Optic Specialists, technicians, quality, test, and other cross-functional teams
- Ability to work effectively in a fast-paced, dynamic environment and manage multiple priorities
- Strong attention to detail and commitment to safety, quality, and execution
- Ability to lift up to 50 lbs occasionally
- Perform activities such as typing, standing, stooping, and sitting, for extended periods of time
- Dedication to safety to mitigate hazards that may include heat, cold, noise, fumes, strong magnets, lead, high voltage, and cryogenics
- Willingness to occasionally travel or work required nights/weekends/on-call
