Photonics Engineer

Qunett is developing the foundational hardware layer for quantum networking. 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, Qunett seeks physicists and engineers who bring technical range, adaptability, and readiness to contribute across disciplines as the technology and team evolve.

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 laser-driven nonlinear/quantum optical experiments that generate and measure biphotons (SPDC) and support system integration (filtering, stabilization, coupling, and detection). The role will own well-scoped experimental modules and deliver measurable improvements in coupling efficiency, stability, and performance.
