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. #LI-Remote
