Olsson

Olsson is an employee-owned engineering and design firm operating across the United States since 1956, with more than 2,000 employee-owners. The company's work spans transportation infrastructure, water resources, federal facilities, data centers, and sustainable land development - sectors where operational technology and networked systems increasingly intersect with cybersecurity concerns. For security professionals, the threat model here is physical-cyber convergence: water treatment controls, transportation management systems, and data center operations all present attack surfaces where engineering decisions carry direct security implications. Olsson's employee-ownership model means stakeholders have a vested interest in long-term system integrity rather than quarterly metrics, which tends to change how risk gets prioritized internally. The firm builds expert solutions and designs aimed at improving communities, operating with a culture described as responsive, transparent, and results-focused. With a presence across U.S. markets, the scale of infrastructure projects creates opportunities for security practitioners who understand both the digital stack and the physical systems it governs.
