Embedded Software Engineer / Firmware Engineer (Agri-Tech / Sensor Systems) (m/f/d)

At Stenon, we are on a mission to democratize soil data. As the global market leader in real-time soil analytics, we empower farmers with actionable insights to improve yield, crop quality, and soil health while reducing costs and environmental impact.

To advance our next generation of soil sensing technology, we are looking for an Embedded Firmware Developer who can build the on-device software that turns hardware measurements into reliable data directly from the field.

As an Embedded Software Engineer / Firmware Engineer, you will take ownership of Linux system development and microcontroller firmware for our soil sensor platform, and work closely as part of our Device Engineering Team. You will implement, optimize  and maintain embedded Linux components alongside robust firmware for microcontrollers, ensuring reliable operation across the full device stack.

Your work will involve interfacing SOC/SOM with our boards hosting different sorts of sensor, managing data acquisition, and enabling reliable communication between distributed system components under harsh outdoor conditions.

You will collaborate with hardware, firmware and backend/cloud teams to bring integration concepts from prototype to production-ready devices. This includes ensuring stable system behavior, reliable Linux system image and firmware boiling down to robust device functionality. You will implement a robust Linux image as well as microcontroller firmware update mechanism. And with the use of Python, you will simplify  complex problems.

• Develop and maintain embedded Linux systems usingYocto for ARM-based platforms (e.g. Raspberry Pi and similar SBCs)
• Configure, extend, and debugYocto build environments,layers, and recipes
• Support and improve Linux-based system bring-up and debugging on new hardware
• Interface embedded Linux systems withmicrocontrollers
• Write firmware that runs on ARM Microcontrollers (e.g. STM32)
• Support on hardware related software development using Python
• Develop tooling forautomation, testing, deployment, and diagnostics
• Collaborate closely with hardware, firmware, and backend/cloud teams
• Participate in code reviews and contribute to improving system architecture and maintainability
  
  
  
  
  

• Solid experience with Linux Distributions

• Practical experience with the Yocto Project (building images, modifying recipes, working with layers)

• Experience with ARM-based embedded platforms (Raspberry Pi or similar SBCs)

• Expert embedded C/C++ knowledge for firmware development

• Experience working with microcontrollers (e.g. STM32, ESP32, or similar)

• Hands-on experience with hardware interfaces (GPIO, UART, SPI, I2C, etc.)

• Good knowledge of Python

• Experience using Git and collaborative development workflows

• Ability to debug complex issues across hardware/software boundaries

• Real-World Impact: Design hardware that goes directly into the hands of farmers, solving global food production and climate challenges.
• Ownership & Growth: A key role in a fast-growing scale-up where you own your area of responsibility with flat hierarchies and fast decision-making.
• Collaborative Culture: Work in a highly productive, international team that values hands-on development and mutual support.
• Year-End Break: Enjoy a paid company-wide closure between Christmas and New Year to recharge and spend time with loved ones.
• Seamless Commuting:  Choose between an ABC Berlin/Potsdam travel pass or a Deutschland-Ticket to keep you mobile.
• Team Spirit: Annual company retreats to warmer climates (last year we went to Gran Canaria), regular social events, and a fully stocked kitchen with coffee, tea, and snacks.
