About The Position

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, dedicated to uplifting everyone, everywhere by being the best way to pay and be paid. At Visa, you’ll have the opportunity to create impact at scale — tackling meaningful challenges, growing your skills and seeing your contributions impact lives around the world. Join Visa and do work that matters – to you, to your community, and to the world. Progress starts with you. What You’ll Do: Own the end‑to‑end lifecycle (design, provisioning, upgrades, maintenance, and decommissioning) of core platform components, including: Cloud infrastructure primitives Kubernetes clusters and cluster services Networking, ingress, and service discovery Service Mesh and supporting data‑plane components Design platform components to be resilient by default, applying SRE principles such as: Fault isolation and graceful degradation Capacity planning and saturation control Reduced operational toil and clear failure modes Lead the design and implementation of infrastructure bootstrap orchestration, including: Automated cluster and environment provisioning Deterministic, repeatable platform bring‑up and teardown Dependency‑aware orchestration across cloud, network, and Kubernetes layers Drive Infrastructure‑as‑Code and GitOps‑first practices to ensure: Platform components are reproducible and auditable Changes are automated, testable, and reversible Manual intervention is minimized or eliminated Identify automation gaps and lead initiatives that reduce human effort, onboarding time, and operational risk. Apply and promote SRE operational excellence practices, including: Clear ownership and runbooks for platform components Participation in on‑call rotation as a platform reliability escalation point Incident response, post‑incident reviews, and problem management Improve day‑2 operations by standardizing upgrade/rollback strategies and reducing MTTD/MTTR. Ensure platform operations align with security, compliance, and internal control requirements. Collaborate with engineering teams across the organization to influence platform adoption, reliability standards, and cloud‑native best practices.
