Full Job Description
POSITION OVERVIEW

We are seeking a Silicon Photonic Engineer to join our rapidly growing team. This is a high-impact leadership role for someone who can shape product direction, translate customer needs into clear technical requirements, and drive cross-functional execution from concept through validation. The ideal candidate brings deep experience with packaged silicon photonics, including optical engine integration, assembly flows, and manufacturing considerations for next-generation optical interconnect products. The successful candidate will work closely with customers, contract manufacturers, suppliers, and internal development teams to meet product objectives while instilling a culture of quality, accountability, and continuous improvement.

What You'll Do:
  • Help Define Product: Help drive product requirements for next-generation optical interconnects, balancing performance, manufacturability, cost, power, and time-to-market.
  • Be the Customer and Product Voice: Serve as the primary technical interface with customers, foundry partners, and suppliers, ensuring product decisions are grounded in real-world use cases, market needs, and execution realities.
  • Drive Cross-Functional Alignment: Create and own clear product requirements, aligning internal engineering teams, external partners, and key stakeholders around priorities, trade-offs, milestones, and deliverables for packaged optics solutions.
  • Analyze and Optimize: Perform critical link analysis, using simulation and modeling to assess impairments like noise and distortion, ensuring our products deliver robust performance in real-world systems.
  • Translate System Goals into Execution: Convert top-level product objectives into actionable requirements for silicon photonics, electronics, firmware, software, validation, and manufacturing partners.
  • Lead Packaged Optics Execution: Guide the development of packaged silicon photonics solutions, including co-packaged optics and optical I/O approaches, with attention to assembly tolerances, fiber attach, thermal constraints, test strategy, reliability, and scale-up readiness.
  • Validate: Define the complete testing strategy, from engineering verification and product validation to system integration. You will define test methodologies, select equipment, and be hands-on in the lab to bring our products to life.


Who You Are:
  • A seasoned technical engineer with hands-on expertise in silicon photonics and packaged optics, with a strong track record of bringing complex products from concept to production.
  • A natural collaborator who thrives in a multi-disciplinary, geographically diverse team environment.
  • A strategic product thinker who can synthesize customer requirements, technical constraints, and business priorities into clear decisions and execution plans.
  • A leader who is just as comfortable presenting a technical roadmap to executives as you are setting up an experiment in the lab.


Key Qualifications:
  • Proven experience in a technical leadership role developing and 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 packaging trade-offs, integration constraints, 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 (EVT, DVT, SVT) and test methodologies for optical systems.
  • Ability to work effectively and drive decisions within a fast-paced, startup environment.
  • Must be hands-on in a lab environment.


Preferred Experience:
  • Experience with test automation frameworks and scripting (e.g., Python).
  • Direct experience working with hyperscale data center customers or suppliers on packaged optics, co-packaged optics, or optical I/O solutions.
  • Experience with fiber attach technologies, optical assembly processes, and package-level integration challenges for silicon photonics products.


Why Join Us?

This is more than a job. It's a chance to get in on the ground floor of a well-funded company set to disrupt a multi-billion dollar market. You will have the autonomy to make a massive impact, the resources to execute your vision, and a significant stake in the company you help build.

What we offer
  • Competitive salary commensurate with experience
  • Comprehensive benefits package including health insurance
  • Professional development opportunities and certification support
  • Access to cutting-edge technology and cloud platforms
  • Collaborative work environment with cross-functional teams
