Job description

ZoomInfo is where careers accelerate. We move fast, think boldly, and empower you to do the best work of your life. You’ll be surrounded by teammates who care deeply, challenge each other, and celebrate wins. With tools that amplify your impact and a culture that backs your ambition, you won’t just contribute. You’ll make things happen–fast.

What You'll do:

• Design & Develop: Build and operate the self-hosted GitHub Actions runner fleet on GKE including autoscaling, reliability tuning, and zombie-runner cleanup.
• GitOps & Delivery: Own the ArgoCD topology powering CI/CD deployments — central architecture, cluster connectivity, ApplicationSets, production reliability (PDBs, replicas, spot-node avoidance), and event-driven flows via Argo Events + GCP PubSub.
• Shared Platform Components: Maintain and evolve the Helm charts and ApplicationSet patterns used by every Kubernetes workload — versioning, release process, backward compatibility, and developer ergonomics.
• Jenkins Platform Ownership: Own and evolve our Jenkins environment including shared libraries, controllers and agents, plugins, credentials integration, JVM upgrades and platform reliability.
• Self-Service Tooling & Migration: build resusable GitHub actions workflows, actions, and templates, while driving migration from Jenkins and partnering on shared developer tooling
• End-to-End Ownership: Lead complex platform projects from architectural design through implementation and long-term maintenance — identifying system-wide bottlenecks before they become outages, and owning the outcomes well past the ship date.
• Operational Excellence: Own pipeline reliability end-to-end — observability with Datadog (dashboards, monitors, runner log analysis, cluster tracing), incident response and on-call rotation via PagerDuty, plus secrets rotation and vulnerability response.
• Global Collaboration: Partner with distributed teams of architects, infrastructure and security engineers, and every product team that consumes the platform — coordinating across time zones to translate their pipeline needs into golden paths, reusable workflows, and self-service tooling.

What you'll bring:

• CI/CD Platforms: Deep expertise in Jenkins administration, Groovy shared-libraries, Docker-based agents, GitHub Actions, reusable workflows, self-hosted runners, secrets management, and pipeline troubleshooting.
• Cloud & Containers: Strong Kubernetes(GKE) administration, cluster optimization, networking, kubernetes internals, and hands on experience with GCP and AWS services
• GitOps & Delivery Tooling: Hands-on experience with ArgoCD (ApplicationSets, sync strategies, alerting), Helm chart authoring and versioning, and Argo Events or comparable event-driven delivery patterns.
• Infrastructure as Code: Strong proficiency with Terraform for GKE clusters, GCP resources, and CI/CD-related modules.
• Observability: Hands-on experience instrumenting and operating pipelines with Datadog — custom metrics, dashboards, monitors, and distributed tracing.
• Incident Response: Experience running production on-call with PagerDuty — rotation management, alert routing, escalation policy design, and post-incident review.
• Artifact & Image Management: Experience with container registries — JFrog Artifactory (including Xray/Curation scanning) and GCP Artifact Registry — and image lifecycle policies.
• Programming: Comfortable shipping production code in at least one of Go, Python, or Node.js — enough to build controllers, GCP Cloud Functions, glue services, and AI-assisted pipeline tooling.
• AI Development: Experience or knowledge building or deploying LLM-based applications, AI-assisted developer tooling, or managing AI infrastructure for engineering workflows.
