Founded in 1944, we are a digitally enabled solutions provider leading the defense, intelligence, and critical infrastructure markets. From bridges that span iconic waterways to missile defense systems that protect nations, we deliver tomorrow's solutions today. Equipped with capabilities to take on any challenge, our agile and disruptive approach lets us deliver solutions at the speed of relevance — across more than 30 countries with over 20,000 professionals worldwide.

We are a company of thinkers and innovators. Our people don't just generate big ideas — they bring them to life. We operate across a vast range of services and markets around the globe, providing flexibility, internal mobility, and meaningful career paths. From urban designers and environmental engineers to missile defense software developers and cybersecurity specialists, our team represents the full spectrum of talent it takes to deliver a safer, more connected world.

We work across two major domains: global infrastructure and national security. On the infrastructure side, we design and deliver transportation systems, urban development projects, water and wastewater solutions, energy programs, and environmental remediation. In national security, we provide cyber and intelligence operations, missile defense system integration, all-domain solutions, space operations, health and biosciences, and spectrum dominance capabilities. We also develop proprietary products — from traffic management platforms to distributed energy resource systems — that help clients operate smarter and safer.

Our purpose is to deliver a better world. When there's a problem — no matter how complex, how dangerous, or how unprecedented — we say 'Challenge Accepted.' We exist to create the future of the defense, intelligence, and critical infrastructure markets, keeping communities connected, protected, and resilient for generations to come.

We lead with integrity and ethics, holding ourselves to the highest standards of governance and operational oversight. Corporate sustainability is woven into our fabric — it's not a program, it's who we are. Through our CARE framework (Cultivating A Responsible Enterprise), we commit to environmental responsibility, social empowerment, and transparent governance. We set high standards for our people, and we expect them to set high standards for themselves.

We are ranked #1 in Program Management by Engineering News-Record — a distinction earned through 80 years of delivering world-class infrastructure and security solutions. We combine deep technical expertise with cutting-edge technology: digital twins, AI/ML, cloud-enabled platforms, and proprietary products like iNET® and Cyberzcape™. Our global footprint, cleared personnel, and trusted relationships with the Intelligence Community, Department of Defense, and government partners worldwide make us uniquely positioned to deliver at scale, at speed, and with lasting impact.

Corporate sustainability is in our fabric, interwoven with our core values, and underpins who we are and how we operate. Through our CARE framework, we address environmental stewardship, social empowerment, and governance integrity. We promote growth and empower our global community of innovators, and we lead with integrity while creating a safer, healthier, more connected, and more secure future. Our FY2024 CARE Disclosures reflect our ongoing commitment to transparent, material reporting to all stakeholders.

We strive to be an employer of choice that actively engages employees in the community and creates rewarding career paths — cultivating a resilient workforce ready for the future. Our social commitments include programs that promote growth, inclusion, and impact across the communities where we live and work around the world.

We are committed to cultivating a diverse and inclusive environment that enables every employee to thrive. Our programs for transitioning military personnel, internships, and global career mobility reflect our belief that a truly resilient workforce draws strength from a wide range of backgrounds, perspectives, and experiences.
