Sr. Site Reliability Engineer

Visa is a world leader in payments technology, facilitating transactions between consumers, merchants, financial institutions and government entities across more than 200 countries and territories.

• Strong hands-on experience with public cloud platforms (AWS preferred, Azure).
• Experience administrating productive Kubernetes environments at scale.
• Experience with service mesh technologies (Istio preferred, App Mesh, Linkerd).
• Strong understanding of observability tooling and Golden Signals concepts.
• Knowledge of incident management concepts and on-call operations.
• Experience with Infrastructure as Code (e.g., Terraform).
• Understanding of cloud-native containerized micro-services architecture.
• Strong collaboration and communication skills.

Platform Ownership & Reliability:

• Own the end-to-end lifecycle (design, provisioning, upgrades, and decommissioning) of core platform components including cloud infrastructure primitives, Kubernetes clusters and cluster services, networking, ingress, service discovery, service mesh and supporting data-plane components.
• Ensure platform components are resilient by design applying SRE principles such as fault isolation, graceful degradation, capacity planning, saturation control, reduced operational toil, and clear failure modes.
• Continuously assess and mitigate reliability risks, proactively improving platform stability and operational readiness.

Infrastructure Bootstrap & Automation Leadership:

• Lead design and implementation of infrastructure bootstrap orchestration including automated cluster and environment provisioning, deterministic and repeatable platform bring-up and teardown, and dependency-aware orchestration across cloud, network, and Kubernetes layers.
• Drive Infrastructure-as-Code and GitOps-first approach ensuring platform components are reproducible, auditable, automated, testable, reversible, and minimize manual intervention.
• Identify automation gaps and lead initiatives to reduce human effort, onboarding time, and operational risk.

SRE Practices & Operational Excellence:

• Apply and promote SRE practices including clear ownership and runbooks for platform components, participation in on-call rotation as platform reliability escalation point, incident response, post-incident reviews, and problem management.
• Improve platform operability by simplifying day-2 operations, standardizing upgrade and rollback strategies, reducing Mean Time to Detect (MTTD) and Mean Time to Recover (MTTR).
• Ensure platform operations align with security, compliance, and internal control requirements.
