What You’ll Do

  • Drive execution of the product development program across the development team for the optical hardware product for high‑speed optical networks.
  • Support and partner with development team members to identify technical gaps and capture solutions for timely execution to meet committed production launch dates.
  • Manage manufacturing partners to ensure completion of technical design activities prior to product launch, including reliability, design verification testing, compliance testing, and reporting.
  • Drive and support cross‑functional teams—including photonics design, hardware design, packaging, manufacturing, quality engineering, product marketing, and supply chain—to ensure robust product development and transfer to production.
  • Drive internal preparation to ensure material readiness to support ongoing customer program engagement.
  • Support engineering and product teams in supplier technical discussions to ensure all necessary details (e.g., models, technical specifications) are available for successful design effort.
  • Support engineering and operations teams to ensure all qualified suppliers meet necessary requirements before production release, including incoming component validation.

  • Strong knowledge in photonics device physics, photonics packaging, and failure mechanisms.
  • Demonstrated success supporting NPI programs and product qualification from concept through volume production.
  • In‑depth knowledge of relevant standards (GR‑468, Telcordia, JEDEC, MIL‑STD) required for successful program release.
  • Effective communicator with the ability to influence cross‑functional and supplier teams.
  • Experience in a fast‑paced, high‑tech environment serving telecom/datacom markets.

Preferred Skills

  • Project management experience in integrated photonics packaging and co‑design (optical + electrical) from design to production release.
  • Hands‑on experience in design‑to‑manufacturability and cost optimization.
  • Willingness and adaptability to unfamiliar areas to ensure program success; willingness to travel to suppliers and manufacturing partners during the design or transfer phase.
