Haley & Aldrich Tech Stack

Environmental engineering and remediation for contaminated sites and water resources

Environmental Services Burlington, MA 501–1,000 employees Privately Held

Haley & Aldrich is a 1,000+ person environmental engineering firm built around geotechnical work, contaminated site assessment, and water treatment. The tech stack is almost entirely domain-specific (AutoCAD, Civil 3D, MODFLOW, Plaxis 3D, ArcGIS suite) with minimal cloud or modern data infrastructure — reflecting a traditional engineering consulting model where field investigation and design dominate over software-driven operations. Hiring skews heavily engineering (160 roles) with smaller pockets in support and sales, matching a project-delivery business that scales through billable technical staff rather than platform growth.
