About the Role

Site Reliability Engineering (SRE)/Platform Engineering at Equifax combines software and systems engineering to build and run large-scale, fault-tolerant systems. SRE ensures services meet reliability and performance expectations while adhering to Equifax engineering principles. This role involves engineering solutions to operational problems, managing overall system operation, and employing various tools and approaches to solve complex challenges. Key practices include limiting operational work, conducting blameless postmortems, and proactively preventing outages. Equifax fosters a culture of diversity, intellectual curiosity, problem-solving, and openness, encouraging collaboration and risk-taking in a blame-free environment.

Responsibilities

  • Design, provision, and manage hardened, secure, cost-optimized GKE and AWS EKS production clusters.
  • Standardize automated, cross-cloud infrastructure delivery utilizing Terraform.
  • Maintain a GitOps model via ArgoCD to match environment state directly to code repositories.
  • Execute Canary deployments (online, live-traffic validation) and Blue-Green deployments (offline/batch, zero-downtime, instant rollback).
  • Architect complex cloud networking topologies including VPCs, Shared VPCs, Peering, Transit Gateways, and Cloud Interconnect/Direct Connect.
  • Manage cross-cloud connectivity and enforce zero-trust network policies within Kubernetes.
  • Implement end-to-end distributed tracing and infrastructure monitoring using DataDog.
  • Build custom dashboards, monitors, and SLO/SLI alerts for deep visibility into app and infra health.
  • Translate Enterprise Architects' high-level blueprints into automated, scalable, and secure technical implementations.
  • Drive AWS/GCP/Azure cost-saving initiatives (rightsizing, Spot/Preemptible instances, storage tiers) and automated governance (tagging, lifecycle policies, budget alerts).

Requirements

  • Requires 7–10+ years of enterprise-scale experience in Platform Engineering, Site Reliability Engineering (SRE), or DevOps.
  • Proven mastery managing production-grade environments across AWS and Google Cloud (GCP), plus Azure experience specifically for cost governance.
  • 4+ years of hands-on experience provisioning and managing EKS and GKE clusters, including production upgrades, hardening, and namespace isolation.
  • Advanced proficiency with Terraform for multi-cloud resource provisioning, utilizing modular, reusable code and state management.
  • Experience building declarative workflows using ArgoCD or Flux, alongside automated pipelines that integrate security scanning, testing, and validation.
  • A proven track record of executing Canary deployments for high-traffic online services and Blue-Green deployments for large-scale batch/offline workloads.
  • Expertise in hybrid architectures (Transit Gateways, Shared VPCs, Direct Connect/Cloud Interconnect) combined with Kubernetes Network Policies and cloud IAM management.
  • Hands-on experience with DataDog APM for distributed tracing, dashboard creation, defining SLIs/SLOs, and configuring alerting logic to reduce MTTR.
  • Capability to lead cloud financial initiatives through workload rightsizing, strategic use of Spot/Preemptible instances, and building automated policy enforcement for cloud spend.
  • Experience collaborating with Enterprise Architects to design systems across the "5 Pillars" (Well-Architected Framework).
  • Highly prefers candidates with CKA (Required), AWS Solutions Architect Professional, Google Professional Cloud Architect, and FinOps Certified Practitioner (FCP).
  • Ability to treat infrastructure as a product to champion the developer experience, leveraging internal portals like Backstage.
  • Experience building custom CLI tools to streamline and simplify the development "inner loop."
  • Possession of a Certified Kubernetes Security Specialist (CKS) credential or deep experience managing production runtime security.
  • Hands-on experience implementing cloud-native security and compliance using OPA (Open Policy Agent), Kyverno, or Falco.
  • Advanced proficiency with Istio, Linkerd, or Consul to govern complex service-to-service communication, mTLS, and traffic shifting.
  • Strong engineering skills in Go or Rust to build custom Kubernetes Operators and CRDs for tailored automation.
  • Experience executing proactive resilience testing and "game days" using Gremlin, AWS Fault Injection Simulator, or Chaos Mesh.
  • Capability to calculate the exact unit cost of a transaction or service to align cloud architecture with business ROI.
  • Experience managing GPU-accelerated workloads on Kubernetes (NVIDIA device plugins) and model pipelines via Vertex AI or SageMaker.
  • Active engagement with the CNCF community and a history of contributing directly to core ecosystem tools like Terraform providers or ArgoCD plugins.
