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

Who are we?

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.

Position

As an Embedded Firmware Developer, you will take ownership of the firmware development for our soil sensor system, including the sensor head electronics and control units deployed in agricultural field environments. You will design robust, real-time firmware that interfaces with optical and electrochemical sensors, manages data acquisition and signal processing, and ensures reliable communication under harsh outdoor conditions.
You will work closely with hardware, optics, and mechanical teams to bring sensor concepts from prototype to field-ready devices, ensuring stable operation, efficient power management, and reliable data transfer in demanding agricultural applications.

You will

• Develop and debug firmware for our soil measurement devices
• Develop software and hardware tools for device diagnostics, testing and validation
• Interface different sensors to MCU or SOM
• Document code
• Collaboration with other team members (hardware and software engineers) to agree system designs, interfaces, and protocols, etc.
• Participate in design and code reviews and recommend improvements
• Support in overall hardware-related software troubleshooting

You have

• A degree within a technical field such as Electrical Engineering, Computer Science or related topic of study (Bachelors/Masters and above)
• 3-5 years of experience with a similar role
• Expert knowledge of C/C++
• Extensive experience writing firmware for embedded systems, bare-metal (on STM32 and STM32CubeIDE, RTOS would be a plus)
• Knowledge of state machine diagram interpretation and implementation to code
• Strong awareness of ARM architecture and Internal Peripherals (Timers, PWM , Interrupts, RTC, ADCs, etc.)
• Strong knowledge of embedded communication protocols including UART, I2C, SPI, and CAN, (USB, ISOBUS, SMBus is a plus)
• Very strong experience with writing sensor drivers
• Proficiency with source control tools such as git
• Experience with build systems/pipelines
• Comfortable using linux shell
• Experience bringing up and debugging circuit boards
• Very comfortable with reading and understanding datasheets
• Strong electrical engineering fundamentals and experience interfacing components
• Proficiency with laboratory equipment including oscilloscopes and logic analyzers
• Preferred - Strong knowledge of Python

What we offer

• 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.

Why us?

We are changing how farmers understand and manage their soil—moving from lab‑based analysis to real‑time insights directly in the field. We value transparency, ownership, and continuous improvement, and we believe great products come from teams that respect and support each other.
We set high standards, reward performance, and foster a positive, constructive feedback culture.
