We are looking for a driven RF/Microwave Engineer to take a key role in the design, development, and testing of next-generation high-power microwave heating systems. The position is linked to an Industrial PhD opportunity at Uppsala University and to the Swedish Energy Agency funded EMBRACE project, in collaboration with RISE Research Institutes of Sweden. The research will focus on microwave-based electrode drying for more energy efficient and sustainable battery manufacturing, while the industrial work will cover RF system design, prototype development, measurement, control, and pilot-scale validation.
You will work from concept to prototype: simulating, fabricating, and characterizing RF components and subsystems, including solid-state power amplifiers, matching networks, antennas, and microwave applicators. The role combines academic research with hands-on industrial development, from early-stage concepts and laboratory validation to pilot-scale deployment.
The ideal candidate combines strong analytical skills with hands-on laboratory experience and is motivated to pursue doctoral research in an environment that blends academic research, product development, and systems-level thinking.
Industrial PhD and EMBRACE Project Context
The candidate will work in an industrial environment at Percy Roc while pursuing doctoral studies at Uppsala University. The doctoral research will be connected to EMBRACE, which develops and validates microwave-based electrode drying as a route to reduce energy consumption in lithium-ion battery manufacturing while maintaining electrode quality and industrial scalability.
Within this framework, Percy Roc contributes microwave-system design, power electronics, and industrialization expertise, while RISE contributes process validation, and scalability assessment. The doctoral work will connect electromagnetic and RF design with thermal process control, measurement, modelling, and pilot-scale verification.
