Senior Process Engineer

The Role

• Develop and mature glass and fiber‑optic assembly processes for new products, from early concept and proof of principle through NPI and production handoff.
• Work hands‑on with high‑end fiber and glass processing equipment (e.g., cleaving, splicing, tapering), serving as the primary technical user responsible for learning, tuning, and advancing these processes.
• Build and test fiber‑optic assemblies leveraging our proprietary photonic crystal fiber platform.
• Design, execute, and analyze experiments to define robust process windows and tolerances.
• Develop, iterate, and maintain clear process documentation to support optimization, repeatability, and transfer to production.
• Troubleshoot complex process issues, drive root‑cause analysis, and implement improvements.
• Work cross‑functionally to support knowledge transfer and production readiness.
• Deliver effective process solutions within PDP timelines, balancing experimentation with repeatability.

The Individual

• 5+ years of experience in process or product development within photonics, optics, or a closely related field.
• Strong background in optical fiber manufacturing or processing; experience with specialty or non‑standard fibers is a plus.
• Experience with optical packaging and other precision assembly processes in controlled manufacturing environments.
• Strong foundation in photonics and laser systems, including the use of laser sources to test fiber‑optic assemblies and support laser‑based applications.
• Background in materials science, physics, or a closely related discipline relevant to optical fiber and glass materials.
• Structured and methodical in approach, with a systematic mindset toward experimentation, data analysis, and process optimization.
• High attention to detail with a strong focus on quality, repeatability, and manufacturability.
• Persistent and resilient in tackling complex, hands‑on technical challenges, with the patience to learn, tune, and master sophisticated equipment.
• Able to operate independently while collaborating effectively across engineering and manufacturing teams.
