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.
