Ionic Wind AG is an Empa spin-off developing the world’s first commercial solid-state airflow generators – a disruptive alternative to fans for laptops, edge AI systems and high-precision instruments. Our modules generate airflow by exploiting principles from plasma physics, having no noise, no vibration As our product gets closer to market, we are offering a 6 months internship to develop, integrate and test the MCU of our airflow units. Your responsibilities -Define the embedded system architecture, including sensor interfaces, control signals, communication protocols, and safety functions. -Evaluate, select, and prototype the most suitable MCU platform, and integrate it with our current power supplies and test infrastructure. -Develop dynamic closed-loop control for high-voltage and current setpoints, including arcing detection, dust mitigation, safety interlocks, and environmental monitoring. -Implement robust communication protocols between the embedded system, power electronics, sensors, and external control software. -Document technical findings and provide actionable recommendations for system integration, scalability, and future product development. Your profile -Highly motivated and curious mindset -Currently enrolled in embedded systems, electrical, mechanical or computer science, or a related discipline at a Swiss university and looking for a mandatory internship or Master Thesis -Hands-on experience with microcontrollers and embedded firmware development, ideally in C/C++ -Familiarity with common communication protocols such as UART and I2C -Experience in hand-on electronics prototyping : PCB design, soldering, field testing -Fluent in English, with German and French as a plus Nice to Have -Familiarity with thermal systems -Familiarity with Fluid mechanics, especially airflow physics -Familiarity with the basics of plasma physics -Experience with CAD, 3D printing -Interest in disrupting technologies -Hands-on skills in testbench setup or experimental physics What We Offer -2300 CHF / month salary (interns) or accommodation stipend (MSc thesis student) -Direct exposure to R&D at the intersection of research and startup innovation. -A unique look into solid-state airflow technologies — beyond what’s possible with fans -Direct exposure to strategic decision-making in a deep-tech startup -Friendly, ambitious team driven by technical excellence and purpose -Optional participation in planned work trips abroad (customer pilot site, suppliers) -Opportunity to stay involved long-term as employee at Ionic Wind AG Please send your CV and short cover letter at [email protected]
