Embedded Systems Intern

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
