Mechanical Engineer (Agri-Tech Sensor Systems) (mfd)

Who are we

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

To advance our next generation of soil sensing technology we are looking for a Mechanical Engineer who can design robust field-ready hardware that survives real agricultural conditions.

Position

As a Mechanical Engineer you will take ownership of the mechanical design of a metal soil sensor head that is inserted into and dragged through soil using agricultural machinery (e.g. tractor-mounted systems). You will design durable manufacturable components that integrate optical sensors (NIR UV-VIS) and electrochemical sensing (EIS) while withstanding abrasion impact moisture and long-term field wear.

You will work closely with electronics optics and production teams to bring designs from concept to CNC-manufactured reality.

You will

Design and develop mechanical components and assemblies for a metal soil sensor head used in harsh agricultural environments

Engineer structures that withstand abrasion impact vibration moisture and long-term soil contact

Select suitable metals coatings and surface treatments to minimize wear and corrosion in the field

Design for CNC machining including tolerances manufacturability and cost efficiency

Integrate optical components such as lenses windows and sensor mounts while ensuring alignment stability and environmental sealing

Collaborate with electronics and optics teams to ensure proper thermal mechanical and environmental interfaces

Create detailed CAD models technical drawings and BOMs

Support prototyping testing and iterative design improvements based on field feedback

Work with production and suppliers to transition designs into small- and medium-scale manufacturing

Contribute to design documentation and engineering change processes

You have

A degree in Mechanical Engineering or a closely related field

Experience designing mechanical systems for outdoor or industrial applications (agri-tech automotive heavy machinery robotics or similar)

Strong understanding of metal properties wear mechanisms and material selection for abrasive environments

Hands-on experience designing parts for CNC machining

Experience with SolidWorks or Fusion 360

Familiarity with sealing concepts (O-rings gaskets IP protection etc.)

Basic understanding of opto-mechanical design (mounting lenses optical windows sensor alignment)

Ability to work across disciplines and translate system requirements into robust mechanical designs

A practical problem-solving mindset with attention to detail

Professional working proficiency in English; German is a plus.

Nice to have :

Background in agricultural machinery or agri-tech equipment design

Experience with surface treatments or coatings (e.g. hardening anodizing PVD nitriding)

Exposure to field testing and iterative hardware development

Experience designing components that interface with soil sand or other abrasive media

Experience with CFD or numerical simulations to analyze a sensor head moving through soil including pressure distribution drag forces and stress / pressure concentration points

Familiarity with using simulation results to optimize geometry for durability reduced wear and stable sensor operation

What we offer

A key engineering role in a fast-growing agri-tech company with real-world impact

An agile international team with flat hierarchies and fast decision-making

The opportunity to design hardware that is used directly by farmers in the field

A collaborative hands-on development environment

Coffee tea and snacks in our office

ABC Berlin / Potsdam travel pass or Deutschland ticket

Why us

We are changing how farmers understand and manage their soilmoving 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.
