Environmental Services Fairfax, Virginia 201–500 employees Founded 1988 Privately Held

CSS is a 201–500-person federal contractor delivering environmental science, compliance, and disaster-response programs to 20+ Federal agencies. The tech stack is heavily weighted toward geospatial analysis (ArcGIS, QGIS, ERDAS Imagine, Global Mapper) and statistical modeling (R, Python, SAS, Stata, SPSS) — typical of mission-critical environmental research. Hiring velocity is accelerating with 17 roles posted in the last 30 days, skewed toward operations and research, but conspicuously sparse in engineering and design (one each), suggesting they're scaling delivery capacity faster than internal product or platform development.
