Job Description

Join Pismo’s Platform squad within the SRE Tribe, dedicated to owning and evolving the containerized platform that underpins critical workloads. You’ll work cross‑functionally to ensure our platform is reliable, scalable, secure, and easy to operate, focusing on Kubernetes at scale and cloud architecture.

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.

• Experience with Infrastructure as Code (Terraform preferred) and automation‑first workflows.
• Familiarity with GitOps practices and CI/CD pipelines.
• Strong troubleshooting skills for distributed systems, including root‑cause analysis and reliability improvements.
• Experience with observability concepts and practices (monitoring, logging, alerting, tracing).

Preferred Qualifications

• Experience with Service Mesh technologies (Istio preferred, App Mesh or Linkerd).
• Experience working with critical or mission‑critical systems.
• Strong background applying SRE principles (operational readiness, incident management, runbooks, toil reduction).
