Your responsibilities include:

• Design and implement embedded software for our measurement devices using ZephyrOS and C/C++
• Possibility to contribute to the development and evolution of our shared software platform
• Take end-to-end ownership of features and modules in mostly independent project setups
• Participate in code reviews, testing and troubleshooting to ensure reliable, industrial-grade products

What will you bring?

• Strong experience in embedded software development, ideally in industrial or instrumentation products
• Excellent programming skills in C/C++, and experience with embedded operation systems. Hands-on experience with ZephyrOS is a strong plus
• Ability to work independently and take ownership of complex development tasks, while collaborating effectively with other engineers and scientists
• Curiosity and a growth mindset to actively explore and apply AI tools in your daily work. Hands-on experience using AI to improve workflows, accelerate development, or solve practical engineering challenges is a strong advantage.
