Senior Scientist / Research Scientist, Photonics Integration and Packaging

Are you interested in innovative photonics and microelectronics devices and looking for a new job opportunity in the field? Would you like to work at the interface of academy and industry? Are you enthusiastic about working with fascinating projects in state-of-the-art research facilities? VTT might be just the place for you.  

VTT is one of the leading applied research organizations in Europe. What unites us at VTT are the curiosity, passion for learning, and devotion to finding solutions to global challenges and answers to our customers’ needs. Our cross-disciplinary community of over 2000 brilliant minds is focused on creating impact through science-based innovation. Get to know us further by exploring VTT’s research infra through VTT World.

We are looking for a Senior Scientist or Research Scientist to join our Photonics and RF Integration team located in Oulu

As a researcher, your key goals are to advance our photonics module technologies for various connectivity and sensing devices. You will plan and carry out research work, publish and disseminate research results, and guide younger researchers and process technicians. You will have a proactive role in communicating with our customer companies and research partners as well as in applying for research funding in collaboration with your VTT colleagues and your networks. You will also manage different kinds of customer contracts and public-funded research projects.

We are building functional photonics modules from bare die devices by applying advanced electronics and photonics assembly and packaging processes in our cleanroom facility. The application sectors for the devices include communications, medical, manufacturing, defense and space. Today we are for instance developing photonics integrated circuit (PIC) based devices for communications and quantum photonic sensors for medical imaging. The module-level integration of photonics is a multidisciplinary research topic that involves optics, optoelectronics, electronics, mechanics, high-precision assembly, and thermal management. It deals with silicon and compound semiconductor chips, ceramic substrates, PCBs, flip-chip and other hybrid integration methods, large-area integration on polymer substrates, optical fibers, lasers, and hermetic sealing, etc.
