Engineering services firm specializing in building systems design and decarbonization
Salas O'Brien is a 1,000+ person engineering services firm anchored in building design, HVAC, electrical, and structural disciplines. The tech stack is heavily weighted toward CAD/BIM tooling (Revit, Navisworks, AutoCAD, BIM 360) and simulation software (ETAP, SCADA, STAAD), reflecting a deep engineering-first culture—not a software company pivoting into services. Hiring remains concentrated in engineering roles (290 of 331 open positions), with senior-level and mid-level engineers dominating the pipeline, suggesting sustained project demand in manufacturing, healthcare, and data center facilities.
Salas O'Brien provides engineering design and technical services to industrial, institutional, and commercial clients. Core competencies include HVAC, electrical, structural, fire protection, and sustainability-focused design—particularly LEED certification, energy efficiency optimization, and decarbonization strategies. The firm operates across the full lifecycle: feasibility studies, design, commissioning, and renovation of existing assets. Recent project activity centers on manufacturing and healthcare facilities, new data center construction, and envelope and interior renovation work. Employee ownership and recognition on engineering industry rankings position the firm as a mid-market player in the AEC services market.
Primary tools include Revit, Navisworks, AutoCAD, BIM 360, ETAP, SCADA, and STAAD—a portfolio tilted toward AEC and industrial engineering simulation. Microsoft Office and Project handle project management.
Active hiring across United States, Canada, and Peru. Headquarters is in Irvine, California.
