Engineering services for telecom rollouts, building systems, and infrastructure projects
STF Gruppe is a 600+ person engineering consultancy based in Dülmen, Germany, serving telecom operators and public infrastructure clients across DACH. The company's project pipeline—fiber expansion for Deutsche Telekom and Vodafone, railway stations, public buildings, mobile network rollouts—reveals a infrastructure-heavy business. Their tech stack (Revit, AutoCAD, BIM, ArcGIS, SD-WAN, Power BI) reflects design and planning workflows typical of large civil engineering; the engineering-dominant hiring mix (68 of 102 open roles) and recurring pain points around fiber planning, project coordination, and cost control suggest they are scaling project delivery capacity while wrestling with operational efficiency in rollouts.
STF Gruppe provides tailored engineering services to large enterprises, mid-market firms, and public sector clients. Their core practices span telecommunications (fiber and mobile network expansion), building systems design and technical planning, IT infrastructure, and digitalization consulting. Operating from over 20 offices across Germany, Austria, and Switzerland, the firm delivers services across the full project lifecycle: planning, design, and project management. The team comprises civil engineers, technicians, IT specialists, business analysts, and geoscience professionals. Founded in 1997 and publicly listed, the company competes on innovation and multi-disciplinary depth rather than single-category specialization.
