Technical Lead, Single Photon Sources Validation

Job Title

Technical Lead, Single Photon Sources Validation

Role Summary

Lead validation efforts for cryogenic electro-optical assemblies that combine single-photon-source photonic circuits and superconducting single-photon detectors. The role owns validation planning, experiment design, data analysis algorithms, and execution of characterization campaigns.

Work cross-functionally with design, test, and lab teams to bring up cryogenic measurement setups and to close feedback loops into product design.

Experience Level

Senior — requires extensive industry experience; the posting specifies 12+ years of relevant industry experience.

Responsibilities

Deliver validation plans, execute cryogenic characterization, and provide technical leadership.

• Define figures of merit and validation plans for cryogenic electro-optical assemblies.
• Design experiments and lead execution, including debugging and characterization of assemblies in cryogenic environments.
• Develop algorithms and data-analysis methods to extract performance parameters from measurement data.
• Bring up and maintain laboratory cryogenic test setups (light sources, detectors, switches, AWGs, oscilloscopes, etc.).
• Develop software scripts to automate measurement sequences and ingest data into databases.
• Collaborate with cross-functional teams to review designs and provide validation-driven feedback.
• Provide technical mentorship to junior engineers and lead cross-functional project delivery.

Requirements

Must-have technical skills and experience; preferred items are listed separately.

• Proven track record leading complex, cross-functional projects from concept to product integration.
• Experience testing single-photon detectors and performing measurements in cryogenic environments.
• Hands-on experience with photonic integrated circuits, especially nonlinear optical PICs.
• Proficiency with optical and electrical test equipment: optical power meters, lasers, OSAs, oscilloscopes, AWGs, VNAs.
• Experience developing test methods, optimization, and tuning/calibration algorithms.
• Comfort writing measurement automation scripts and integrating data into databases or analysis pipelines.
• Strong debugging skills for hardware-in-the-loop and cryogenic systems.
• Ability to communicate results and technical recommendations to engineering and product teams.
• Nice-to-have: prior experience with photonics quantum experiments.

Education Requirements

Bachelor's degree or above in Engineering, Physics, or Materials Science. The posting also specifies 12+ years of industry experience.
