Job summary

Munich Quantum Valley is seeking a Photonics Engineer to join the founding team as Photonic Interface & Interferometry expert in the Munich area.

You will design and build photon collection, fiber coupling and routing, develop stable interferometers for Bell-state measurement, and integrate SNSPDs and telecom components to advance quantum connectivity.

Qualifications

• PhD with relevant experience in photonics, quantum optics or AMO physics.
• Hands-on experience building stable interferometers and single-photon setups.
• Solid grounding in feedback control, loop design and locking techniques.
• Fiber optics and precise optical alignment.

Responsibilities

• Design and build photon collection, fiber coupling and routing in a compact form factor.
• Design and build interferometers for Bell-state measurement and two-photon interference that stay stable over hours of operation.
• Engineer their stability, both passive (thermal, mechanical, polarisation) and active (phase and path-length locking, feedback loop design).
• Integrate and calibrate single-photon detectors (SNSPDs) and telecom components.
• Contribute to the laser systems: beam delivery, modulator lines, frequency stabilisation.
• Track loss, noise and drift budgets from atom to fiber.

Job description

QMunicate – Photonics Engineer Photonic Interface & Interferometry (f/m/d)

Join the founding team developing the connectivity layer for future quantum technologies — at the intersection of quantum optics, hardware engineering and scalable infrastructure.

Photonics Engineer — Photonic Interface & Interferometry

You build the node's photonic interface: the optics that collect single photons from the cavity and route them over telecom fiber, and the stable interferometers that measure their entanglement.

Responsibilities

• Design and build photon collection, fiber coupling and routing in a compact form factor
• Design and build interferometers for Bell-state measurement and two-photon interference that stay stable over hours of operation
• Engineer their stability, both passive (thermal, mechanical, polarisation) and active (phase and path-length locking, feedback loop design)
• Integrate and calibrate single-photon detectors (SNSPDs) and telecom components
• Contribute to the laser systems: beam delivery, modulator lines, frequency stabilisation
• Track loss, noise and drift budgets from atom to fiber

Requirements

• PhD with relevant experience, in photonics, quantum optics or AMO physics
• Hands-on experience building stable interferometers and single-photon or low-light setups
• Solid grounding in feedback control: loop design, noise analysis and locking techniques
• Fiber optics and precise optical alignment

Nice to have

• Fiber-based or polarisation-stabilised interferometers
• Hands-on experience with optical design software (e.g. Zemax)
• SNSPDs and time-correlated photon counting
• Optomechanical design of compact, robust setups (CAD)

What we offer

• A founding-team role with real ownership of a first-of-its-kind machine
• A new quantum-optics lab in the Munich area
• Competitive salary and employee equity (VSOP)
• Close ties to the European quantum ecosystem; conference and training budget
• English as working language
