Infrastructure engineering group for energy transition and mobility projects
TREYSTA is a 500-person engineering holding with 10 subsidiaries across 25 German locations, focused on infrastructure design for energy and mobility transition. The tech stack is CAD-centric (AutoCAD, BricsCAD, Civil 3D, Revit, BIM) with survey and project-management tools (Trimble, Leica, Microsoft Project), reflecting traditional AEC workflows. Active projects span water systems, rail infrastructure, and drainage networks, while hiring has decelerated with a senior-heavy mix and a documented pain around recruiting experienced engineers — a structural constraint in German infrastructure markets.
TREYSTA Ingenieure Holding is a holding company operating a network of 10 mid-sized engineering offices across Germany. The group specializes in complex infrastructure projects tied to energy transition and mobility shifts: water systems (drinking-water supply, rainwater treatment, sewer rehabilitation), rail infrastructure planning, and utility network design. The company operates from 25 locations in Germany and employs approximately 500 staff. Work involves civil engineering design, GIS applications, permitting coordination, and construction supervision. The organization is privately held and founded in 2021.
