The role combines deep technical expertise in enterprise networking with strong consulting, troubleshooting, and stakeholder management skills.

Responsibilities:

Application Discovery & Dependency Mapping
Lead network flow discovery and traffic analysis activities to identify application communication patterns and dependencies.
Assess east-west and north-south traffic flows across data centers, cloud environments, and third-party connectivity.
Develop and maintain application dependency maps, connectivity matrices, and migration runbooks.
Partner with application owners, architects, and infrastructure teams to validate connectivity requirements and identify migration risks.
Establish baseline network behavior and ensure dependencies are understood prior to migration events.
Non-Functional Requirements (NFRs)
Facilitate the definition and validation of network-related non-functional requirements.
Ensure resiliency, availability, performance, latency, scalability, recoverability, and operational support requirements are identified and documented.
Participate in architecture reviews to validate that proposed designs meet business and technical objectives.
Identify potential network bottlenecks, single points of failure, and operational risks before implementation.
Network & Security Architecture Design
Design and evolve connectivity architectures supporting application modernization and migration initiatives.
Define required modifications to network services and infrastructure, including:
DNS and IP Address Management (IPAM)
Routing and network segmentation
Firewall policy design and rule optimization
Web Application Firewall (WAF) integration
Load balancing and traffic distribution
Internet and partner connectivity
Cloud networking and hybrid connectivity
Network resiliency and disaster recovery architectures
Collaborate with security architecture and engineering teams to ensure designs align with enterprise security standards and Zero Trust principles.
Provide technical leadership during solution design workshops and architecture reviews.
Migration Execution & White-Glove Support
Act as a dedicated technical resource during critical application migration and cutover activities.
Provide hands-on support to application, infrastructure, cloud, and identity teams throughout migration events.
Troubleshoot and resolve complex connectivity, name resolution, authentication, authorization, and application access issues.
Identify gaps in network, security, and identity readiness and drive remediation activities to closure.
Support migration readiness reviews, go/no-go decisions, and post-migration validation activities.
Coordinate incident resolution across multiple technology teams when issues arise during migration windows.
Operational Excellence
Develop standards, patterns, and repeatable migration methodologies.
Contribute to continuous improvement initiatives focused on automation, observability, and operational efficiency.
Participate in root cause analysis and problem management activities following major incidents or migration events.
Create and maintain technical documentation, architecture diagrams, implementation procedures, and operational runbooks.
Provide technical mentorship and guidance to project teams and junior engineers.

Experience troubleshooting application connectivity, authentication, authorization, and performance issues across hybrid environments.
Experience designing and implementing resilient network and security architectures.
Strong knowledge of cloud networking within Azure and/or AWS.
Excellent communication and stakeholder management skills, with the ability to work directly with application owners, architects, and business stakeholders.
