Sr Principal Architect- Network Product Line

You're a senior architecture professional who wants to influence the future of global network connectivity in a large-scale enterprise. As a Senior Principal Architect at JPMorganChase within Network Services, you will provide specialized expertise to influence target state architecture and strategy for the firm's foundational connectivity layer, Network Connectivity Services. You will work across Network Services domains (backbone/transport, data center, edge, campus, reliability engineering, and common tooling) to drive architectures that improve resiliency, predictability, and cost effectiveness of global connectivity. Job responsibilities Advise and lead architecture strategy for Network Connectivity Services across a global portfolio, including connectivity resiliency, circuit diversity, and optical transport lifecycle Define and maintain reference architectures, standards, and patterns for transport connectivity (physical diversity principles, redundancy models, turn-up and lifecycle patterns, and resiliency validation approaches) Partner with backbone/transport engineering and other network domains to ensure underlay decisions integrate cleanly with overlay/backbone designs and cross-domain initiatives Drive architectural governance for the domain through design reviews and Architecture Decision Records (ADRs), ensuring decisions are traceable, reusable, and aligned to target state Translate complex technical trade-offs (latency, diversity, capacity, cost, operational risk) into clear options and recommendations for senior leaders and stakeholders Lead or support evaluation of current and emerging transport technologies and vendors (line systems, coherent optics, monitoring/telemetry approaches), including proof-of-concept work where appropriate Establish or improve the architectural approach to carrier/provider connectivity services, including service design principles, SLAs/SLOs, and operational guardrails (in partnership with service owners) Architect the planning data foundations for connectivity services (inventory and topology models, circuit attribution, resiliency metrics) and collaborate with common tooling/data initiatives to operationalize them Embed security, risk, and control requirements into connectivity and transport architectures, supporting auditability and operational excellence Mentor and influence engineers and architects, building shared patterns and raising the level of architecture discipline across the organization Required qualifications, capabilities, and skills Formal training or certification on engineering concepts and 10+ years of applied experience in network/transport engineering, architecture, or adjacent infrastructure domains Demonstrated expertise in large-scale WAN/transport connectivity, carrier circuit services, and resiliency engineering (diversity, failover design, fault domain containment) Strong practical knowledge of optical transport concepts and architectures (e.g., DWDM/OTN fundamentals, capacity planning considerations, lifecycle and upgrade strategies) Proven experience influencing across functions and teams to drive modern architecture outcomes and achieve alignment without direct authority Experience applying new methods to solve complex architecture problems across multiple technical disciplines (network operations, automation, data/inventory, security, and governance) Ability to evaluate current and emerging technologies to recommend the best solutions and approaches to achieve future state architecture Strong written and verbal communication skills, including the ability to explain technical risk and trade-offs to non-specialist stakeholders Preferred qualifications, capabilities, and skills Experience with connectivity inventory, topology data modeling, and integrating planning data into automation/observability platforms Practical experience with automation and infrastructure-as-code approaches applied to network domains (e.g., declarative configuration, workflow automation, validation)
