Job summary

Qunett is seeking a Photonics Engineer to contribute to the photonics team building entangled photon sources and quantum frequency conversion systems. This role is highly hands-on, focused on designing, assembling, and characterizing low-noise, phase-coherent modules for qubit exchange between telecom and visible wavelengths.

The position emphasizes nonlinear optics and quantum frequency conversion, with potential free-space or integrated photonics approaches, based in Boston, MA, onsite.

Qualifications

• PhD in Physics, Optics, Electrical Engineering, or related field (or MS with equivalent experience).
• Hands-on experience with nonlinear optics and/or quantum optics in laboratory settings.
• Extensive experience with spectroscopic-grade laser systems (alignment, safety, modulation, stabilization).
• Experience building and troubleshooting optical setups: free-space and fiber coupling, ABCD matrix analysis and implementation, beam shaping, polarization management, interferometers, and low-noise detection.
• Exposure to single-photon sources and/or single-photon detectors (e.g., SNSPDs/APDs), timing electronics, and basic coincidence measurements.
• Experience using optical design / engineering tools (e.g., Zemax/OpticStudio) to design, tolerance, and iterate optical layouts.
• Familiarity with modern software/AI-assisted tools for coding, optimization, and experiment control (e.g., Python-based analysis and automation).
