Multi-disciplinary civil and environmental engineering consulting
RETTEW is a 201–500-person civil and environmental engineering firm founded in 1969, headquartered in Lancaster, PA. The tech stack—Civil 3D, OpenRoads, MicroStation, VISSIM, HydroCAD, SAP2000, GPS/GNSS, GIS, plus 3D visualization tools (Revit, Navisworks, Lumion, Blender)—reflects deep domain specificity in infrastructure design and survey work. Active hiring skews heavily toward senior and mid-level engineers, with a notable focus on leadership roles (Survey Party Chief, Structural Lead), suggesting efforts to scale project delivery across regions while managing competing deadlines and regional workload imbalances.
