Job Description

The Sr. Platform Engineer is a senior individual contributor within the SRE Tribe, responsible for owning and evolving the containerized platform that underpins critical workloads. This role acts as a technical reference for platform reliability, resilience, and automation, ensuring infrastructure components are designed, built, and operated according to SRE and cloud-native best practices.

This engineer is expected to lead by example through hands-on contributions, deep technical expertise, and cross-team influence, particularly in the area of infrastructure bootstrap orchestration and automation at scale.

Key Responsibilities:

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, and service discovery

  • Service Mesh and supporting data-plane components

Ensure platform components are resilient by design, applying SRE principles such as:

  • Fault isolation and graceful degradation

  • Capacity planning and 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 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 a strong Infrastructure-as-Code and GitOps-first approach, ensuring:

  • 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 significantly reduce human effort, onboarding time, and operational risk.

SRE Practices & Operational Excellence:

Apply and promote SRE practices across the platform, 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 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.

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.

Qualifications

Strong hands-on experience with:
Public Cloud platforms (AWS preferred, Azure)
Kubernetes at scale, previous experience administrating productive kubernetes environments
Service Mesh technologies (e.g., Istio preferred, App Mesh, Linkerd)

Strong understanding of:
Observability tooling and Golden Signals concepts
Incident management concepts and oncall operations
Infrastructure as Code (e.g., Terraform)
Cloud-Native containerized micro-services architecture
Strong collaboration and communication skills.
