Your Team, Your Impact We are seeking a Sr. Principal Photonics Engineer to join our Advanced Technology Infrastructure team. This role is instrumental in pathfinding and developing next-generation optical test and assembly infrastructure for high-speed, high-density photonic and co-packaged optical devices. The ideal candidate will bring deep technical expertise in photonic design, optomechanics, and test systems, and will collaborate across disciplines to deliver scalable, manufacturable, and reliable solutions from early silicon through production.

Requirements

Bachelor's degree in Optical Engineering, Photonics, Physics, or related fields and 15+ years of relevant experience, or Master's/PhD in Optical Engineering, Photonics, Physics, or related fields with 10-12 years of experience.
Proven experience in photonic test and packaging, including wafer-level, engine-level and fiber-coupled optical systems.
Strong background in optomechanical design, optical alignment, and vibration mitigation.
Proficiency with simulation tools such as Zemax, Lumerical, and Ansys for optical and mechanical modeling.
Familiarity with optical test equipment (e.g., lightwave component analyzers, optical power meters, lasers) and integration with ATE or SLT platforms.
Excellent communication and cross-functional collaboration skills.
Self-motivated, detail-oriented, and capable of leading complex photonic infrastructure projects from concept to deployment.

Nice To Haves

Architect level test experience with co-packaged optics, silicon photonics, or high-speed optical interconnects is highly desired.

Responsibilities

Lead the design, simulation, and validation of photonic test and assembly systems, including optical probe hardware, lens assemblies, and alignment platforms.
Develop and qualify optomechanical solutions for wafer-level and package-level optical testing, including co-packaged optics (CPO) and standalone optical engines.
Drive BOM creation, vendor engagement, and prototype validation for optical test, including fiber assemblies, loopbacks, blind-mates, and passive optics.
Collaborate with mechanical, thermal, automation, and product engineering teams to ensure seamless integration of photonic systems into test infrastructure.
Define and execute evaluation plans, margining, and correlation studies for optical performance and alignment robustness.
Support development of optical test vehicles and alignment systems for NPI and high-volume manufacturing.
Analyze optical system performance, identify root causes of variation, and drive continuous improvement in alignment accuracy, repeatability, and throughput.
