Nice to have:


Miraex is looking for an intern in optics to join our team and help us in the development of our new integrated photonic chip. Your duties will include the design, fabrication and use of optical test setups for the validation of optical components. You may participate in the development of experimental optomechanical modulation systems via simulations, theoretical calculations and experiments. In that aim, you will use the metrology instruments available in Miraex’s labs.

This internship will give you experience in a small and horizontal R&D team, where every voice is heard and each new challenge is an opportunity to learn something new. You will be able to expand your metrology skills, mentored by our team with a long development experience.


  • Master in optics or optoelectronic engineering.

  • Knowledge in fiber optics.

  • A hands-on, practical attitude (our team is too small to not get your hands dirty!).

  • Ability to design and simulate optical systems (FTDT, BPM, Zemax).

Skills that will make the difference

  • Knowledge in sensors.

  • Knowledge in microfabrication

  • Knowledge in electronics and light sources (laser, SLED, ...).

  • Independence, critical thinking and synthesis capacities

  • A strong computational thinking.

  • Knowledge in Python and UNIX environment CAD design (SolidWorks, Catia, Fusion360, FreeCAD)

  • Experience with scientific instruments.


Miraex develops, manufactures and offers cutting-edge ultra-high-precision photonics and quantum solutions for next-generation sensing, networking and computing.

Our industrial photonic sensing solutions detect asset failure before it occurs, in the most demanding environments (ATEX), where standard electronic sensors do not work.

At Miraex we also build quantum integrated circuits for high-sensitivity measurements and distributed quantum-computing infrastructures.

An award-winning start-up with strong support from : Innovaud, Innosuisse, EPFL, Swissnex network, IBM Q network, Venture Kick, Venturelab, ESA Business Incubation Center, IMD business school, European Photonics Industry Consortium, TOP100 Swiss start-up, Creative Destruction Lab, etc.

We are located in the city of Lausanne, Switzerland on the shores of lake Geneva offering an incredible quality of life.


  • Being part of a fast growing investor-backed company in two very exciting and growing fields: sensors for predictive maintenance & industry 4.0 and Quantum Computing.

  • A team that has a strong footprint in two worlds: product development and advanced R&D.

  • Exciting possibilities to put your knowledge into practice: work hands-on on direct problems for clients as well as more research-like topics.

  • Highly attractive working environment, in the heart of the Lake Geneva region in Switzerland.

  • 4 to 12 months internship, full time.
