Network Architect at Capitaltg · LumiJobs

Responsibilities

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.
Design, engineer, implement, and support secure, resilient enterprise cloud, network, and hybrid infrastructure solutions supporting mission systems and shared services.
Develop and implement secure connectivity solutions spanning cloud and on-premises environments.
Translate mission, technical, security, and architecture requirements into implementable infrastructure and network solutions.
Produce and assess physical and logical architecture diagrams, routing and segmentation designs, interfaces, connectivity, capacity, availability, resiliency, and monitoring requirements.
Provide senior-level hands-on engineering throughout the infrastructure lifecycle, including design, configuration, implementation, automation, migration, testing, troubleshooting, deployment, and operational support.
Configure, integrate, and troubleshoot cloud and hybrid infrastructure components and services.
Ensure solutions meet requirements for scalability, availability, security, performance, interoperability, maintainability, cost effectiveness, and operational support.
Provide technical guidance to engineers and resolve complex cloud infrastructure, networking, connectivity, performance, and cross-domain issues.
