Our mission is to build scalable, field-deployable quantum networks through solid-state quantum memory and networking technologies designed to operate beyond the laboratory and integrate directly with real-world infrastructure. At Qunett, physicists and engineers work hands-on with diamond-based quantum devices, photonics, cryogenic systems, and control electronics to translate fundamental quantum capabilities into practical networked hardware. This is a ground-floor opportunity to help shape how quantum systems communicate, scale, and drive the next generation of secure communication, distributed sensing, and quantum computing. As an early-stage company actively building out its quantum memory and photonics teams, Qunett seeks physicists and engineers who bring technical range, adaptability, and readiness to contribute across disciplines as the technology and team evolve.\nWork Location\nThis is a full-time, onsite position based in Boston, MA.\nAbout the role\nQunett 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, quantum frequency conversion modules for qubit exchange between telecom and visible wavelengths. Efficient methods of bandwidth exchange between broadband photons from SPDC and narrowband light appropriate for color-center qubits will be essential. Free-space implementation and/or integrated photonics approaches are envisioned. This role will focus on nonlinear optics and quantum frequency conversion within the broader photonics efforts at Qunett.\nRequired qualifications\nPhD in Physics, Optics, Electrical Engineering, or related field (or MS with equivalent experience)\nHands-on experience with nonlinear optics and/or quantum optics in laboratory settings\nExtensive experience working with spectroscopic-grade laser systems (alignment, safety, modulation, stabilization fundamentals)\nExperience building and troubleshooting optical setups: free-space and fiber coupling, ABCD matrix analysis and implementation, beam shaping, polarization management, interferometers, and low-noise detection\nExposure to single-photon sources and/or single-photon detectors (e.g., SNSPDs/APDs), timing electronics, and basic coincidence measurements\nExperience using optical design / engineering tools (e.g., Zemax/OpticStudio or equivalent) to design, tolerance, and iterate optical layouts\nFamiliarity with modern software/AI-assisted tools for coding, optimization, and experiment control (e.g., Python-based analysis and automation)\nPreferred qualifications\nExperience with SPDC-based entangled photon sources (Sagnac or interferometric geometries), biphoton characterization, and/or HOM-type interference measurements\nExperience with wavelength-division multiplexing concepts (filters, DWDM components), insertion-loss management, and polarization gates\nExperience with laser spectroscopy in solid-state, atomic, or ion systems\nExposure to micro/nanofabrication or photonic device integration\nFamiliarity with quantum networking requirements (entanglement distribution, link budgets, interface constraints)\nBenefits\nComprehensive health coverage including medical, dental, vision, and prescription plans\n401(k) retirement plan\nEquity participation through stock options for all new hires\nFlexible time off: unlimited PTO, sick leave, and 11 paid holidays\nEmployee support benefits including EAP, caregiver support, healthcare advocacy, and more","description_format":"text","description_chars":3690,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity","Flexible
