Site Reliability Engineer

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.

This is a remote position. A remote position does not require job duties be performed within proximity of a Visa office location. Remote positions may be required to be present at a Visa office with scheduled notice.
