About this position
Electronics Integration and Reliability (EILB) at Aalto University School of Electrical Engineering is seeking a doctoral researcher to work on the next generation of high-density power electronics. The group develops innovative materials, device design, and bonding technologies for wide-bandgap and ultra-wide-bandgap semiconductor systems, with applications extending to RF devices and smart sensors.
The project centers on miniaturised heterogeneous integration for power electronics, using novel high-temperature interconnects such as solid–liquid interdiffusion, hybrid and diffusion bonding, and sintering. The research will examine how interconnect compatibility, metallurgy, microstructures, and local interface defects affect electrical and thermal performance as well as the long-term reliability of power electronic modules.
The successful candidate will help design, manufacture, and characterise highly integrated, ultra-high-power-density power modules and “power chiplets”. The work combines advanced materials characterisation, electrical and thermal measurements, and multiphysics modelling to support innovative control and sensing functions in compact power systems.
The doctoral researcher will work in a collaborative environment that includes international research partners and participation in large national and pan-European public-private partnership projects. The position is based at Aalto University’s OtaNano infrastructure, with opportunities to use Micronova and the Nanomicroscopy Center for research and characterisation.
The role sits within a broader Aalto research environment focused on science, technology, innovation, and multidisciplinary collaboration in Espoo, Finland.

What's required
Applicants should have an M.Sc. or equivalent degree in a suitable area such as electrical engineering, physics, or materials science. Strong knowledge and understanding of wide-bandgap and ultra-wide-bandgap power semiconductor technologies is required, along with experience in multiphysics simulation tools such as COMSOL and ANSYS and circuit design tools like SPICE or PLEX. Experience of working in a cleanroom is expected, or at least a genuine interest in advanced microfabrication, novel interconnection, and material characterisation methods. Experience or genuine interest in electronics reliability assessment and failure analysis tools is also desired, together with strong analytical and writing skills. Selected candidates must then apply for the study right in doctoral studies at Aalto University School of Electrical Engineering and should check the doctoral programme admission criteria.
How to apply
Submit the application through Aalto’s recruitment system by 14 December 2026. Upload all required documents as a single PDF in English in the specified order. Do not apply by email. If you are already working at Aalto, apply via the internal Workday system.
