GO Engineering

What GO Engineering does

GO Engineering (G.O. Engineering GmbH) is a German electronics manufacturing services (EMS) provider founded in 1990 by Helmut Gerstner and headquartered in Bühl, Baden-Württemberg. The company designs, develops, and manufactures durable electronic assemblies for industrial OEMs, with core competencies in power electronics, drive technology, e-mobility, and industrial electronics. Its manufacturing footprint includes multiple SMD lines with capacity for up to ~3 million components per week across ~4,000 m² of production area, supported by proprietary process technology including the C-Method (Ziehsystem) pull system and a Europe-wide unique high-precision coating robot. The company holds ISO 9001 and ISO 14001 certifications, maintains an in-house IPC A 600/610 trainer, and is pursuing IATF 16949 to access automotive customers.

GO Engineering serves manufacturers of trucks, construction equipment, agricultural machinery, mining equipment (e.g., rock drills), industrial knitting machines, and handheld power tools, delivering both electronic assemblies and reference designs. Success-story products include frequency converters for rock drills with IoT-connected HMI, digital carburetor heating controllers operating down to -40 °C, and high-efficiency (92–97%) wide-range industrial power supplies with battery backup. The development function follows a V-Model with requirements definition, 3D modeling, and hardware/software verification; software is implemented primarily in C/C++ for embedded targets.

The company operates a B2B enterprise sales model with custom-quoted engineering and manufacturing services delivered through direct field sales (Paul Wörner, Head of Sales Management) and a technical project management team that shepherds customers from order intake through series production. Revenue is derived from EMS contract manufacturing fees and professional engineering services. GO Engineering was acquired by Sweden-based Concentric AB (Nasdaq Stockholm) on October 1, 2024 to advance the parent's electrification, electric liquid cooling, and thermal management strategy, and currently operates as a subsidiary within the Concentric Group with ~120+ employees.
