Senior Network Architects are responsible for enterprise network architecture, modernization, and security across DoW mission environments (IL4/5/6). This role sets standards and roadmaps; leads end to end design for data center, campus/branch, WAN/SD WAN, and cloud connectivity; and drives Zero Trust-aligned segmentation and automation to deliver resilient, scalable, and compliant networks., Strategy & Architecture Governance: * Participate in Architecture Review Boards (ARB) and Change/Configuration Control Boards, maintaining traceability with HLD/LLD, ADRs, ICDs, and security overlays. * Evaluate emerging capabilities (e.g., EVPN VXLAN fabrics, SD WAN/SASE, advanced telemetry) with adoption criteria, risk posture, and migration approaches * Develop and maintain network architecture roadmaps, standards, and best practices aligned with DoW and Agency requirements. Core Network Architecture & Design: * Design underlay/overlay topologies for data centers and campuses (spine leaf, EVPN VXLAN, MPLS L2/L3VPN) and for WAN/backbone (BGP/OSPF/IS IS, traffic engineering, route policy, communities). * Engineer HA and fast convergence (ECMP, FHRP, FRR, ISSU/GSU) and plan for capacity, growth, and performance (QoS, queuing, shaping, policing). * Define IPv4/IPv6 addressing strategy, NAT policies, multicast/RP design where required, and DNS/DHCP/IPAM governance. Security Architecture & Zero Trust: * Architect segmentation and micro segmentation (identity /policy based), secure access (802.1X, certificate based auth), and crypto/crypto boundary designs (IPsec, MACsec) using FIPS validated algorithms. * Align to DoW RMF, NIST SP 800 53/37, and DISA STIGs; map control inheritance and produce artifacts needed for ATO/cATO. * Integrate network security controls (firewall policy frameworks, IDS/IPS, SWG, DLP) and validate with tabletop/blue team exercises. Cloud, Edge & Cross Domain Connectivity: * Design hybrid and multi cloud connectivity (IL cloud constructs, private connectivity, transit/segmentation, inspection service insertion, east west control). * Engineer remote access/telework, edge footprints, and mission partner/coalition interconnects with explicit security demarcation and monitoring. * Campus & Branch * Define campus access, distribution, and core designs with 802.1X, posture assessment, guest/IoT segmentation. * Establish branch patterns (SD WAN, DIA/MPLS mix, local breakout controls) with consistent policy and centralized governance. Automation, Reliability & Observability: * Drive intent based and policy driven operations: configuration standards, golden baselines, compliance drift detection, and repeatable change. * Establish observability requirements (model driven/streaming telemetry, logs/metrics/flows) and SLOs; ensure runbooks and test plans cover failure scenarios. * Documentation & Deliverables Produce and maintain: * Enterprise Network Standards, High/Low Level Designs (HLD/LLD), Architecture Decision Records (ADRs), Interface Control Documents (ICDs), test/validation plans, cutover plans, security overlays, addressing/IP plans, and runbooks., Lead end-to-end execution of packaging category sourcing across assigned markets: manage supplier relationships, run RFP/RFI and contract negotiations, ensure supply continuity and risk mitigation, drive supplier performance and cost optimization, and collaborate with cross-functional teams to deliver category outcomes for the QSR system.
