SEH Tech Stack

Civil engineering and design firm serving water, transportation, and infrastructure sectors

Civil Engineering St. Paul, Minnesota 501–1,000 employees Founded 1927 Privately Held

SEH is a 501–1,000-person engineering and design practice built around water/wastewater treatment, transportation, and infrastructure renewal. The tech stack is heavily weighted toward desktop CAD and GIS tools (AutoCAD Civil 3D, Revit, ArcGIS, MicroStation, Trimble suite), reflecting a project-driven, design-first operation — no adopting or replacing signals suggest a stable, mature toolset. Hiring pressure is decelerating across 257 open roles, with engineering dominating headcount but notable depth in finance and construction teams, indicating a services business scaling through project delivery rather than product development.
