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

published since: 


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
