R&D Engineer – Ultrafast Laser Microfabrication & Photonic Packaging

Location: Madrid, Spain
Expected starting date: October 2026
On-site
 
Join us in developing one of the most promising manufacturing technologies for the future of photonics and semiconductor packaging.
LASING Microsystems is looking for a highly motivated engineer or physicist to join our R&D team and lead the development of Selective Laser-Induced Etching (SLE), an emerging ultrafast laser technology capable of creating complex three-dimensional microstructures inside glass with accuracy down to the micron. 
This technology is opening new opportunities in integrated photonics, photonic packaging, quantum technologies, semiconductor manufacturing, micro-optics and microfluidics, and is expected to play an increasingly important role in the next generation of optical and electronic devices. The project focuses on bringing this technology from cutting-edge research into robust industrial manufacturing solutions.
The selected candidate will join LASING’s R&D team and will also have the opportunity to pursue a fully funded Industrial PhD in collaboration with the Universidad Politécnica de Madrid (UPM).
 
What you will do
  • Develop ultrafast laser processes for advanced 3D glass microfabrication.
  • Design and optimise laser processing strategies using femtosecond lasers.
  • Work with advanced optical systems, beam shaping and precision motion platforms.
  • Fabricate and characterise photonic components such as fibre alignment structures and micro-optics.
  • Develop new industrial capabilities for next-generation laser processing platforms.
  • Collaborate with leading researchers in applied photonics.
  • Publish scientific results and participate in international conferences.
 
We are looking for
Required
  • MSc degree in Physics, Photonics, Optical Engineering, Telecommunications, Materials Science, Mechanical Engineering or related discipline.
  • Strong interest in experimental R&D.
  • Hands-on engineering mindset.
  • Good communication skills in English.
 
Experience in one or more of the following will be highly valued
  • Ultrafast laser materials processing (fs/ps).
  • Optical system design and alignment.
  • Beam shaping (Bessel beams, SLMs, DOEs, axicons, etc.).
  • Integrated photonics or photonic packaging.
  • Motion control and scientific instrumentation.
  • Optical metrology and microscopy.
  • Precision engineering or automation.
 
What we offer
  • The opportunity to work on one of the fastest-growing technologies in advanced manufacturing.
  • A key role in developing future industrial laser processing platforms.
  • Access to state-of-the-art ultrafast laser laboratories and optical instrumentation.
  • Collaboration with leading research groups in photonics.
  • Participation in international conferences and high-impact scientific publications.
  • Continuous technical training and professional development.
  • Fully funded Industrial PhD opportunity with Universidad Politécnica de Madrid.
  • Competitive salary according to experience.
