Silicon Photonic Engineer
LumilensJob Title
Silicon Photonic Engineer
Role Summary
Lead the development and delivery of packaged silicon photonics and optical interconnect products. Translate customer needs into technical requirements and drive cross-functional execution from concept through validation, working with customers, foundries, suppliers, contract manufacturers, and internal teams.
Experience Level
Mid-Career technical role with leadership responsibilities. The posting describes a technical leadership position but does not specify years of experience.
Responsibilities
Accountable for product definition, cross-functional coordination, technical execution, and validation of packaged silicon photonics solutions.
- Define product requirements for next-generation optical interconnects balancing performance, manufacturability, cost, power, and schedule.
- Serve as primary technical interface to customers, foundries, suppliers, and contract manufacturers.
- Lead alignment across hardware, firmware, software, validation, and manufacturing teams, tracking milestones and trade-offs.
- Perform optical link analysis using simulation and modeling to assess impairments and system-level performance.
- Drive packaged optics development including assembly tolerances, fiber attach, thermal constraints, reliability, and scale-up readiness.
- Define test strategies and plans (EVT, DVT, SVT); select equipment and perform hands-on lab validation.
- Translate system-level goals into actionable requirements for silicon photonics, electronics, firmware, and manufacturing partners.
Requirements
Must-have technical skills and experience required to perform the role; preferred items listed separately.
- Proven experience in a technical leadership role delivering photonics-based products.
- Deep expertise in silicon photonics design, performance characteristics, and trade-offs.
- Direct experience with packaged silicon photonics or optical engine development, including integration and manufacturing considerations.
- Demonstrated ability to perform optical link budget analysis using simulation and modeling.
- Experience defining product requirements and driving execution across hardware, firmware, software, validation, and manufacturing teams.
- Experience defining test plans and test methodologies for optical systems (EVT, DVT, SVT) and hands-on lab validation skills.
- Ability to work effectively in a fast-paced startup environment and lead cross-functional teams.
Preferred:
- Experience with test automation frameworks and scripting (e.g., Python).
- Direct experience with hyperscale data center customers or suppliers on packaged/co-packaged optics or optical I/O.
- Experience with fiber attach technologies, optical assembly processes, and package-level integration challenges.
Education Requirements
Not specified.
