About Us

ECS was founded in 1993 in Tampa, Florida, originally as Energy Conservation Specialists, an energy services company. It later evolved and reoriented towards software engineering in 2001, under the leadership of Roy Kapani, shifting its focus to delivering advanced technology, science, and digital solutions.

Headquartered in Fairfax, Virginia, ECS employs nearly 4,000 people across the United States and serves a diverse client base including military, federal civilian agencies, and commercial sectors. The company is committed to innovation and quality, maintaining ongoing investments in processes, standards, and certifications to ensure excellent delivery.

ECS specializes in science, engineering, and advanced technology solutions such as cloud computing, cybersecurity, artificial intelligence (AI), machine learning (ML), data, and enterprise transformation. It emphasizes flexible delivery models and strategic partnerships with leading technology providers.

In 2018, ECS was acquired by On Assignment (ASGN), a publicly traded company, which expanded ECS’s capabilities and market reach. ECS operates as a segment of ASGN, providing critical and complex solutions across the U.S. public sector and commercial industries. The company holds Microsoft Gold-certified partnership status and maintains specialized certifications in cloud and AI/ML technologies.

ECS’s mission is to partner with leading organizations to deliver powerful solutions in a fast-paced, digital world, driven by innovation and a customer-first approach.
