About the Role

We are seeking a Subject Matter Expert (SME) Network Architect to join our team supporting the U.S. Census Bureau on a large-scale federal modernization program. This is a senior, hands-on technical role responsible for designing, engineering, implementing, and modernizing secure, resilient network and cloud infrastructure supporting mission-critical systems and shared services across cloud and on-premises environments.

The successful candidate will combine deep networking and cloud engineering expertise with enterprise architecture responsibilities, translating mission and technical requirements into scalable, secure, highly available cloud and hybrid infrastructure solutions. This role remains hands-on throughout the engineering lifecycle, from architecture and technical design through configuration, implementation, automation, migration, testing, troubleshooting, and operational transition.

You'll produce technical designs and architecture artifacts, including physical and logical diagrams, while working directly with cloud, platform, network, security, and engineering teams to implement and support the environments those designs represent. The role will also support current-state assessments, target-state architecture, modernization roadmaps, architecture governance, and technical gap analysis.

This is a hybrid role based out of Suitland, MD. Candidates must be U.S. citizens and able to obtain and maintain a Public Trust clearance.
