Senior Platform Engineer, CI/CD & Kubernetes

ZoomInfo; Toronto; On-site; CAD 120,000 - 180,000; Full time

Job summary

ZoomInfo is hiring for a Platform Engineer who will design and operate CI/CD platforms, focusing on self-hosted GitHub Actions runners on GKE and ArgoCD topology. You will own Jenkins, Helm charts, and IaC workflows while enabling global teams with reusable pipelines and tooling.

You will drive end-to-end pipeline reliability, observability, and incident response, collaborating with architects, infrastructure and product teams across time zones to deliver scalable, resilient systems.

Qualifications

• Proven expertise in building and operating CI/CD platforms and pipelines.

Responsibilities

• 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.
