EA Engineering, Science, and Technology, Inc., PBC Tech Stack

Environmental engineering and remediation services across infrastructure, compliance, and coastal resilience

Environmental Services Hunt Valley, MD 501–1,000 employees Founded 1973 Privately Held

EA Engineering is a 700+ person environmental and infrastructure firm operating across 25+ U.S. offices (plus Alaska, Hawaii, Guam). The tech stack reveals a shift toward data infrastructure: alongside traditional CAD/GIS tools (AutoCAD, ArcGIS Pro, Esri), the company runs Neo4j, MongoDB, Delta Lake, and Python/Scala — suggesting internal efforts to consolidate hazmat remediation, compliance, and habitat datasets into queryable systems. Engineering-heavy hiring (19 roles open) signals either project volume growth or capacity strain in field investigation and design work.
