TYLin Tech Stack

Global infrastructure design and engineering for transit, water, and mobility systems

Civil Engineering San Francisco, California 1,001–5,000 employees Privately Held

TYLin is a 1,000–5,000-person engineering firm anchored in San Francisco, designing transit corridors, wastewater systems, and water infrastructure. The tech stack reveals a CAD-heavy, design-first operation: Revit, Civil 3D, MicroStation, and OpenRoads dominate; simulation tools (VISSIM, HEC-RAS, SAP2000) and GIS (ArcGIS, QGIS) sit alongside project controls (Primavera P6, Microsoft Project). No adopting or replacing signals—the stack is stable and mature. Hiring is heavily engineering-skewed (270 of 351 roles), with senior and mid-level staff concentrated there, and pain points cluster around schedule/cost control and complex multi-phase delivery—typical of large-scale public-sector infrastructure work.
