Optical Process Engineer information

What does an optical process engineer do?

An Optical Process Engineer designs, develops, and improves manufacturing processes for optical components such as lenses, mirrors, and filters. They work to ensure high-quality production by optimizing fabrication techniques, troubleshooting process issues, and collaborating with design and production teams. Their responsibilities often include process validation, quality control, and the integration of new technologies to enhance optical component performance and efficiency.

What are the key skills and qualifications needed to thrive as an optical process engineer?

To thrive as an Optical Process Engineer, you need a strong background in optics, physics, and engineering principles, often supported by a bachelor’s or master’s degree in optical engineering or a related field. Familiarity with optical design software (such as Zemax or Code V), cleanroom processes, and relevant manufacturing and metrology equipment is typically required. Analytical thinking, attention to detail, and effective teamwork are essential soft skills that help address complex technical challenges and collaborate across functions. These competencies are crucial for developing high-precision optical components and ensuring efficient, reliable manufacturing processes.

What are some common challenges faced by optical process engineers in a manufacturing environment?

Optical Process Engineers often encounter challenges related to maintaining tight tolerances and consistent quality during the fabrication of optical components. Variations in material properties, precision alignment, and contamination control require careful process monitoring and troubleshooting. Additionally, scaling up from prototyping to full-scale production can introduce complexities in process stability, equipment calibration, and cross-functional collaboration with design and production teams. Staying up-to-date with evolving manufacturing technologies is also important to ensure process efficiency and product quality.

Optical - Director Optical Engineering

Eliyan

San Francisco, CA • On-site

$150 - $200/hr

Other

Posted 15 days ago

Job description

Eliyan is building NuLink, a proprietary die-to-die chiplet interconnect fabric purpose-built for AI infrastructure at hyperscale. As we extend NuLink into optical domains, we are seeking a Director Optical Engineering (DOE) to lead optical engineering execution at Eliyan, owning the hands‑on integration of external optical components with Eliyan's silicon die. This is not a component design role — it is an optical integration and implementation role within a semiconductor packaging context. The DOE must be fluent in semiconductor fabrication and assembly processes in order to engage credibly with silicon and process engineering teams and to make sound integration decisions at the intersection of optics and semiconductor manufacturing.

KEY RESPONSIBILITIES
  • Lead evaluation, characterization, and qualification of external optical components (VCSELs, PDs, lenses, fiber interfaces) for integration with Eliyan's silicon die.
  • Own optical implementation within the package — defining integration schemes, alignment tolerances, and coupling strategies in coordination with packaging and silicon teams.
  • Engage directly with process engineers and silicon designers on fabrication feasibility, stack‑up decisions, and yield‑impacting integration choices.
  • Define and execute system demonstrations, including lab bring‑up of optically co‑packaged silicon and customer‑facing demo builds.
  • Develop and maintain optical test infrastructure: on‑wafer and packaged‑device optical probing, E-to-O/O-to-E characterization, link budget validation, BER testing.
  • Coordinate closely with OPD on information flow, ensuring engineering execution aligns with product‑level requirements.
  • Report engineering milestones and integration status to the COA.
QUALIFICATIONS
  • 10+ years in optical engineering with direct experience in optical integration within semiconductor packaging environments.
  • Solid working knowledge of semiconductor fabrication and assembly processes — including FEOL/BEOL fundamentals, wafer‑level packaging, and die‑attach methods — sufficient to identify process‑driven constraints on optical integration.
  • Comfortable engaging directly with process engineers and silicon designers on fabrication feasibility, stack‑up decisions, and yield‑impacting integration choices.
  • Experience with process‑aware optical design: understanding how fab tolerances, surface topography, and material properties affect optical coupling and alignment.
  • Hands‑on experience with short‑reach optical components (VCSEL arrays, PD arrays, lens assemblies, fiber coupling) and their assembly constraints.
  • Strong lab skills: optical probing, frequency‑domain characterization, jitter/BER analysis, link budget validation.
  • Familiarity with co‑packaging assembly processes — alignment tolerances, solder reflow effects on optical coupling, underfill impact on optical paths.
  • Experience working with silicon analog/digital teams on joint bring‑up and debug.
  • MS or PhD in Electrical Engineering, Photonics, or related field preferred.
