Hardware/PCB Design Engineer (m/f/d)

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 develop our next generation of soil sensors, we are looking for a Hardware/PCB Design Engineer who can design the electronic systems and boards that deliver reliable data directly from the field.

Position:
As a Hardware / PCB Design Engineer, you will take ownership of the electronic hardware design for our soil sensor system, including sensor interfaces, power management, and communication modules integrated into a rugged metal sensor head. You will design reliable, manufacturable PCBs that integrate optical and electrochemical sensing components, ensuring signal integrity, noise immunity, and long-term durability in harsh agricultural environments.
You will work closely with firmware, mechanical, and production teams to bring electronic designs from concept and schematic capture through prototyping, validation, and scalable manufacturing.

You will:
• PCBA design for manufacturing, utilizing understanding of various manufacturing processes
• Power electronics design, Analog, and Digital circuit design, Impedance matching
• Schematic creation, prototyping and bringup, reliability, and production.
• Schematics capture and PCB layout in Altium Designer
• Characterization of in-house designed and off-the-shelf components
• Simulation and modeling using circuit simulation tools
• Documentation of performed experiments/measurements

You have:
• Degree in Electrical Engineering or comparable Studies. 
• 3-5 years of experience in a similar role
• Power electronics experience such as buck boost, flyback, DCDC, BMS, etc.
• Experience bringing up and debugging circuit boards
• Strong proficiency with laboratory equipment including oscilloscopes and logic analyzers
• Strong experience with Altium Designer. Impedance Matching, Signal Integrity.
• Experience with LTspice or other circuit design simulation software is advantageous
• Good understanding of different protocols like I2C, SPI, CAN, UART, USB.
• Excellent reading, writing, and spoken communication skills
• Extremely motivated and excited to take on major responsibility at an early startup
• Good English language skills are desirable

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.

Interested?:
If you are ready to tackle the challenge of making complex soil data instantly accessible and actionable for farmers worldwide, we want to hear from you.
