About the role
We are seeking a Principal Engineer, Silicon Photonics 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.
What they're looking for
- A seasoned technical leader with deep 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
- Proven experience in a principal-level technical leadership role developing and delivering photonics-based products
- Deep expertise in silicon photonics design, performance characteristics, and trade-offs
