Biogas plant control systems and process automation
Sauter Biogas develops proprietary biogas digestion systems for agricultural, municipal, and industrial customers across Europe. The tech stack is heavily weighted toward industrial automation (TwinCAT, CODESYS, Beckhoff, Siemens S7, PROFINET) — a clear signal that the core product is hardware-centric plant control rather than software-as-a-service. Hiring remains junior-to-mid-level across engineering and construction, with internal focus on control system development and process optimization.
Sauter Biogas designs and deploys biogas plants using a patented mechanical aeration system positioned as an alternative to traditional stirring methods. Over 50 installations operate globally across farms, municipalities, and industrial sites. The company operates in Germany with a small, flat-hierarchy team building proprietary plant control systems, reusable automation function libraries, and coordinating on-site construction. Their tech foundation spans industrial PLC programming (TwinCAT 3, CODESYS, IEC 61131-3) and CAD (Autodesk Inventor, AutoCAD) for system design and commissioning.
TwinCAT 3, CODESYS, Beckhoff, Siemens S7, TIA Portal for control; PROFINET and Modbus for networking; Autodesk Inventor and AutoCAD for engineering design; Windows 10/11 for operations.
