Senior Photonics Test Engineer

Responsibilities

• Arcitect, design, and build die-level and wafer-level photonic test beds from scratch, including probe stations, optical and electrical probing, fixturing, alignment automation, instrumentation, and environmental controls.
• Own the day-to-day operation of the test beds: run die-level and wafer-level test campaigns, maximize throughput and uptime, and maintain calibration and measurement repeatability.
• Develop automated test software in Python for instrument control, wafer maps, data acquisition, analysis pipelines, and reporting dashboards.
• Work with photonic design engineers and foundry partners to define verification specs, test structures, and pass/fail criteria for photonic integrated circuits (PICs) and close the loop on design-fab-test iteration cycles.
• Generate test reports and statistical yield analyses to properly document every die, wafer, and lot, and communicate results to a multidisciplinary team of engineers and scientists.
• Develop and de-risk critical test methodologies and components to enable the next generation QPU.

Qualifications

• Bachelor's or master's degree in electrical engineering, physics, optical engineering, or a related field.
• Minimum of 3 years working as a Test Engineer or Photonics Engineer with hands-on responsibility for photonic or semiconductor device testing.
• Demonstrated experience standing up new test infrastructure: specifying, procuring, integrating, and bringing up wafer probers or die-level test stations for photonic or optoelectronic devices.
• Hands-on laboratory skills with fiber optics and free-space optics, including fiber-to-chip and edge/grating coupling, active alignment, lasers, detectors, and optical modulators.
• Strong automation experience and programming in Python; experience programming lab equipment using SCPI, PyVISA, or LabVIEW.
• Knowledge of fundamental electrical, mechanical, and optics concepts, and experience with hardware debugging.
• Familiarity with wafer-level test concepts such as wafer maps, known-good-die screening, process control monitoring (PCM), and statistical yield analysis.
• Excellent documentation and communication skills, including the ability to explain test procedures and measurement data.

Preferred Qualifications

• Experience testing photonic integrated circuits at a foundry, OSAT, or high-volume photonics manufacturer.
• Experience with automated probe stations and wafer handling equipment (e.g., FormFactor/Cascade, MPI, Maple Leaf Photonics).
• Experience with cleanroom protocols and handling of bare die and wafers.
• Experience building test data infrastructure (databases, dashboards, analysis pipelines).
