OMA is a 201–500-person architecture and urbanism firm founded in 1975, operating from Rotterdam with offices in New York, Hong Kong, and Australia. The tech stack is firmly rooted in parametric design (Rhino, Grasshopper, Revit, V-Ray) and visualization, with emerging focus on data-driven design solutions and BIM automation — signaling a shift toward computational methods and process tooling. Current hiring concentrates on design roles alongside legal and business operations, reflecting both design delivery intensity and internal risk-management scaling.
OMA combines traditional architectural practice with AMO, a research and design studio extending architectural thinking beyond buildings into strategy, communications, and cultural projects. The firm is led by seven partners including founding principal Rem Koolhaas, and maintains a global delivery model across four continents. Current workload spans major under-construction projects (museums, towers, civic buildings, transport infrastructure) and recent completions across North America, Europe, and Asia. Internal operations are navigating contract management, legal/financial risk mitigation, and coordination across distributed BIM workflows — typical pain points for large-scale international design practices managing parallel capital projects.
OMA's primary tools are Rhino, AutoCAD, Revit, and Grasshopper for parametric modeling, paired with V-Ray and Enscape for visualization, and Adobe Creative Cloud (Illustrator, InDesign, Premiere, After Effects) for documentation and communications.
OMA is headquartered in Rotterdam, South Holland, Netherlands. Additional offices operate in New York, Hong Kong, and Australia.
