Site Reliability Engineer - Sr. Consultant Cloud Network Platform at Visa

The Senior Consultant – Network Platform Engineer is a senior individual contributor within the SRE / Platform organization, acting as a technical authority for cloud, hybrid, and global network architecture, reliability, and operations. This role is responsible for designing, evolving, and supporting network platforms that interconnect cloud environments, physical datacenters, and external providers in a secure, scalable, and resilient manner. This position requires deep expertise in Azure networking, with active responsibility for AWS networking, physical datacenters, and datacenter service providers. While network engineering is the core focus, experience with platform and cloud disciplines is considered a strong advantage. Key Responsibilities Network Architecture & Global Topology • Design and evolve global network topologies spanning Azure, AWS, physical datacenters, and third‑party providers. • Define scalable, resilient, and secure network architecture patterns for hybrid and multi‑cloud environments. • Act as a technical reference for routing strategies, segmentation, connectivity models, and traffic flows. Cloud & Datacenter Networking • Own the design and evolution of network components, including: • Virtual networks, subnets, routing, and traffic control • Load balancing, ingress/egress, and DNS • Connectivity between cloud environments and physical datacenters • Work directly with datacenter providers, carriers, and network vendors to design and operate connectivity. Reliability & Operational Excellence • Ensure network platforms meet availability, performance, and resiliency requirements. • Apply SRE principles to networking, including redundancy, fault isolation, graceful degradation, and capacity planning. • Proactively identify risks and single points of failure across global network topologies. Automation & Infrastructure as Code • Drive network automation through Infrastructure as Code and standardized deployment patterns. • Define and evolve automated provisioning, configuration, and validation for network resources. • Reduce manual network operations and operational risk. Incident Management & On‑Call • Participate in on‑call rotations as a senior escalation point for network‑related incidents. • Lead troubleshooting, incident response, and root cause analysis for complex network failures. • Drive improvements from post‑incident reviews to prevent recurrence. Cross‑Discipline Collaboration • Collaborate with platform, Kubernetes, security, and application teams to ensure network designs support platform and workload needs. • Contribute to platform discussions where networking intersects with Kubernetes, DevOps, and cloud architecture. • Mentor engineers on network architecture, troubleshooting, and operational best practices.
