Infrastructure engineering for aviation, transportation, and water systems
Lochner is an 80-year-old engineering firm serving aviation, surface transportation, and water infrastructure across the United States. The tech stack is entirely domain-specific—Civil 3D, Bluebeam, MicroStation, Primavera P6, HEC-RAS, SWMM—with no evidence of adopting or replacing tools, suggesting a mature, operationally stable organization focused on execution rather than transformation. Engineering-heavy hiring (138 of 162 active roles) concentrated in senior and lead ranks signals scaling of delivery capacity for complex, regulated projects.
Notable leadership hires: Traffic Studies Lead, Transportation Engineering Lead, HR Director
