Optical - Director (+), Optical Product Development (OPD)

Posted 2 weeks ago

About the job

Eliyan develops AI infrastructure chips and co-packaged optics for hyperscale data centers. The VP will lead optical product strategy, component selection, and integration, working with silicon and optical teams to enable advanced packaging solutions.

Requirements

  • 12+ years in optical systems
  • Experience with semiconductor fabrication
  • Knowledge of co-packaging architectures
  • Experience with optical component integration
  • Strong cross-functional communication

Qualifications

  • Deep fabrication process knowledge
  • Familiarity with packaging design rules
  • Experience qualifying optical components
  • Understanding optical-electrical tradeoffs
  • Standards-body experience (plus)

Full job description

Eliyan is building NuLink, a proprietary die-to-die chiplet interconnect fabric purpose-built for AI infrastructure at hyperscale.  As Eliyan expands into co-packaged optics (CPO), the Director (or higher-level depending on experience) of Optical Product Development owns the product strategy for integrating third-party optical components — VCSELs, photodetectors, lenses, and fiber interfaces — with Eliyan's silicon die at the package level. This role requires deep familiarity with semiconductor fabrication and assembly processes, as all optical integration decisions are constrained by and executed within a semiconductor packaging environment.


KEY RESPONSIBILITIES

  • Define optical product strategy centered on die-level co-packaging of external optical components with Eliyan's silicon.
  • Own the optical component selection and qualification process (VCSELs, PDs, lenses, fiber connectors), evaluating vendors against system performance and assembly compatibility requirements.
  • Drive assembly-aware optical product specifications — accounting for flip-chip tolerances, solder reflow constraints, alignment accuracy, and packaging design rules.
  • Engage silicon process and design teams on equal footing, translating optical requirements into process-compatible constraints and vice versa.
  • Navigate optical-electrical co-design tradeoffs within foundry process boundaries (e.g., TSMC, GlobalFoundries, or equivalent).
  • Serve as the primary interface between optical and silicon teams (analog/digital), ensuring bidirectional feed-in/feedback between optical integration requirements and silicon design.
  • Partner with Marketing to define product positioning, customer-facing optical specifications, and roadmap priorities.
  • Report execution status and product milestones to the COA

QUALIFICATIONS

  • 12+ years in optical systems or photonic integration, with substantial hands-on experience in semiconductor fabrication, assembly, or advanced packaging environments.
  • Solid working knowledge of semiconductor fabrication processes — FEOL/BEOL concepts, lithography constraints, metal layer stackups, and how process design rules affect optical integration feasibility.
  • Deep understanding of co-packaging architectures — flip-chip bonding, micro-bump interconnects, interposer-based integration, or equivalent.
  • Experience qualifying and integrating third-party optical components (VCSELs, PDs, optical subassemblies) into semiconductor packages.
  • Familiarity with packaging design rules and their implications for optical alignment yield.
  • Experience navigating optical-electrical co-design tradeoffs within foundry process boundaries.
  • Strong cross-functional communication skills across silicon, packaging, and marketing teams.
  • Standards-body experience (IEEE 802.3, OIF, CPO Consortium) a plus.
