Job Description

Lead Network Convergence Architect

Miratech

• Take full ownership of High-Level and Low-Level Design (HLD/LLD) for network infrastructure, defining and documenting target-state architecture across WAN and SD-WAN, routing and switching standards, Data Center Interconnect (DCI), and hybrid connectivity across on-premise data centers and AWS Cloud. • Design the target-state architecture by developing standardized LLD routing and switching templates used by the ETL data pipeline for automated configuration generation. • Design the Transition State Machine (TSM), including interim routing steps and temporary logical overlays required for seamless migration of legacy sites with zero packet loss. • Act as the senior escalation point during large-scale rollouts, resolving complex issues from undocumented legacy configurations by engineering transition solutions aligned with the defined Golden Standard, and securing Architecture Review Board approval for any necessary deviations. • Analyze failed site cutovers within the rollback feedback loop. Identify root causes, engineer corrective solutions, and collaborate with the ETL/Automation team to ensure permanent fixes are embedded into Jinja2-based automation scripts. • Provide technical direction for lab validation activities conducted by Infrastructure Analysts within AWS/EVE-NG simulation environments. • Serve as a trusted advisor to technical and executive stakeholders, applying a consultative approach to challenge legacy decisions, reduce technical debt, defend the target architecture, and translate engineering trade-offs into clear business value (ROI, OPEX reduction, risk mitigation). • Drive architecture governance as the primary technical authority in Architecture Review Board (ARB) sessions, securing design approvals, resolving cross-domain conflicts, and guiding domain architects in preparation and quality assurance of all ARB submissions.

Job Requirements

  • 12+ years of expert-level experience in service provider or large enterprise network architecture, with CCIE (Routing & Switching / Service Provider) or equivalent expertise.
  • Deep expertise in complex routing protocols (BGP, OSPF, IS-IS), including route leaking, VRF segmentation, and SD-WAN overlay/underlay integration.
  • Experience in network engineering and traffic management across global service providers, including GTT, Cogent, and Lumen.
  • Experience working with colocation and data center environments, including Equinix (LD5/LD6) and Redcentric.
  • Knowledge of cloud connectivity and Network-as-a-Service (NaaS) platforms, including Equinix Fabric, Megaport, and PacketFabric.
  • Proven experience leading technical architecture for large-scale M&A network consolidations, including resolving overlapping IP spaces (strong NAT/PAT expertise).
  • Strong understanding of scalable, template-driven network design enabling automated deployments.

Benefits

  • Culture of Relentless Performance : join an unstoppable technology development team with a 99% project success rate and more than 30% year-over-year revenue growth.
