The Opportunity We are seeking a highly experienced Cloud Infrastructure Engineer to design, build, and evolve the Google Cloud Platform (GCP) infrastructure that powers our cloud-native SaaS platform. This is a deeply technical, hands-on engineering role requiring strong production experience with Google Kubernetes Engine (GKE), Kubernetes infrastructure, Terraform, and cloud networking , preferably on GCP. You will be responsible for the foundational infrastructure that supports our engineering organization, including Kubernetes clusters, GCP networking, infrastructure automation, identity and access management, and shared infrastructure services. We are looking for engineers who have directly designed, built, operated, and troubleshot complex Kubernetes environments running on cloud providers—not simply deployed applications into existing clusters. What You'll Do • Design, build, operate, and maintain production infrastructure on Google Cloud Platform (GCP), including GKE, VPC networking, load balancers, Cloud DNS, IAM, and related cloud services. • Own the architecture and lifecycle of Kubernetes clusters, including provisioning, upgrades, node pool management, autoscaling, networking, capacity planning, and operational troubleshooting. • Develop and maintain Terraform modules, infrastructure-as-code frameworks, and automated provisioning workflows that enable consistent, reliable infrastructure management. • Troubleshoot complex infrastructure issues across Kubernetes, Linux, networking, DNS, cloud services, and distributed systems. • Design and maintain GCP networking infrastructure, including VPCs, subnetworks, firewall rules, routing, NAT, load balancing, and connectivity between services and environments. • Build and improve infrastructure observability using Prometheus, logging systems, metrics, alerting, and related monitoring tools. • Implement and maintain infrastructure security controls, including IAM policies, service accounts, secrets management, and least-privilege access patterns. • Drive infrastructure reliability, scalability, performance, and cost optimization across our GCP environment. • Plan and execute major infrastructure upgrades, migrations, and architectural improvements while minimizing production risk. • Partner with Platform Engineering, SRE, and Security teams to establish scalable infrastructure patterns and clear technical ownership. • Participate in technical design reviews, architecture discussions, and mentorship of other engineers. Required Qualifications Cloud Native Infrastructure, Google Cloud Platform (GCP) preferred • 3+ years of hands-on production experience , including designing, provisioning, operating, and troubleshooting cloud infrastructure. • Deep practical knowledge of GCP networking, including VPCs, subnets, firewall rules, routing, Cloud NAT, Cloud DNS, and Cloud Load Balancing. • Experience managing GC
