Process Engineer

Drawing on 50 years of experience, Lumibird designs, manufactures, and distributes laser solutions for scientific, industrial, and medical use from its various sites in the USA and abroad (France, Italy, Slovenia, Sweden, Australia, etc.). Distinguished by its expertise, numerous patents, steady growth, and a workforce spanning roles from production operators to research scientists, the Lumibird Group currently employs over 1,000 people worldwide.

Firmly committed to sustainable development, the Lumibird Group contributes to the ecological and social transition by implementing an ambitious CSR policy.

To support our expanding operations, we are currently seeking candidates for our West Springfield, Massachusetts site.

The Process Engineer is responsible for the development, transfer, control, and continuous improvement of fiber laser manufacturing processes. The role has approximately equal responsibility for transferring new products and processes from R&D into production and for sustaining and improving released products. This is a hands‑on position that spends significant time on the production floor, builds and troubleshoots fiber lasers and subassemblies, develops manufacturing procedures from direct technical knowledge, and establishes effective process controls.

Key process areas include fiber preparation, stripping, cleaving, fusion splicing, fiber‑component processing, laser assembly and performance, electrical and mechanical assembly, and manufacturing yield.

• This position has no direct supervisory responsibilities but is expected to provide technical leadership, training, and certification of production employees.

• Develop, document, qualify, implement, monitor, and improve manufacturing processes for fiber laser products and subassemblies.
• Establish and maintain robust processes for fiber preparation, including coating removal/stripping, cleaning, cleaving, fusion splicing, splice protection, fiber routing, and fiber-component assembly.
• Support and improve laser cavity and optical assembly, electrical and mechanical assembly, laser testing, calibration, and product performance processes.
• Transfer new products and processes from R&D into production by establishing manufacturing readiness, process flow, BOMs, routings, tooling, fixtures, work instructions, control plans, acceptance criteria, and training requirements.
• Spend significant time on the production floor and independently build, evaluate, and troubleshoot fiber lasers and subassemblies to validate processes and resolve manufacturing issues.
• Create and revise standard operating procedures (SOPs), work instructions, workmanship standards, and process specifications based on direct process knowledge and hands‑on experience.
• Define critical process parameters, process windows, in‑process controls, inspection points, and required manufacturing records.
• Plan and execute process qualifications, validations, design of experiments (DOE), process capability studies, and statistical process control (SPC), as appropriate to the process and risk.
• Develop and maintain process failure mode and effects analyses (PFMEAs) and manufacturing control plans.
• Monitor and analyze first‑pass yield, scrap, rework, cycle time, labor hours, throughput, and other manufacturing metrics; lead actions to improve quality, consistency, productivity, and cost.
• Lead or support root‑cause investigations, NCR/MRB activities, corrective actions, and verification of corrective‑action effectiveness.
• Support engineering change orders (ECOs) by assessing manufacturing impact, implementing approved changes, updating affected documentation and training, and verifying post‑implementation effectiveness.
