Principal Infrastructure Architect, ZoomInfo

• You've gotten patterns adopted without owning the teams. A track record of landing platform standards across an engineering organization through ADRs, prototypes, and benchmarks rather than mandate
• You've run the baseline at scale. Hands-on architecture and operation of Kubernetes (GKE preferred) and GCP infrastructure for many teams, with Terraform and GitOps modules other teams consumed. You know what broke in production and what pattern came out of it
• You ship code, not only diagrams. You've written the code or IaC to prove a pattern under load, and turned a production fix (over-provisioned nodes, idle accelerators, a runaway egress bill) into something reusable
• You have depth in a few of the areas above. Enough fluency in the others to evaluate and review designs across all of them
• Bachelor's degree in Computer Science, related technical field, or equivalent practical experience
• 10–15+ years of cloud infrastructure, platform engineering, or SRE experience, including several years establishing shared platform standards

Desirable

• As a Principal Infrastructure Architect on our Infrastructure Architecture team, you'll set technical direction that spans every part of the platform: cloud, networking, security posture, and delivery
• You will join a team of architects that governs standards, leads architecture reviews, and partners with engineering teams to move the platform forward
• This is a generalist architect seat with room to lean into your specialty. The baseline is Kubernetes, cloud infrastructure, standard networking practice, GitOps, and the ability to write an ADR and defend it
• Depth areas are CI/CD and delivery, AI/ML infrastructure, enterprise networking, and service mesh. We don't expect deep experience across all of them; we expect real depth in a few and the ability to dive into the others as needed
• We are optimizing for the judgment and breadth to see a pattern from prototype to adoption: setting vision, running POCs, and partnering with runtime owners to land them
• Leadership and communication rather than positional authority turn direction into adopted patterns here. We value a willingness to dive in as a hands-on technical contributor when a critical initiative calls for it
• Runtime patterns. Design and maintain reference patterns for GKE (cluster and namespace topology, workload identity, autoscaling, upgrade strategy, multi-tenancy), shipped as Terraform modules and GitOps workflows
• Network, Identity and security baseline. Provide the standard cloud network patterns (shared VPC topology, IAM inheritance, private connectivity to managed services, load balancing, DNS, egress and cost modeling) and baseline security controls in partnership with security architects
• Delivery and reliability guardrails. Partner with platform engineering on IaC standards, policy gates, SLO practices, multi-region and DR patterns with RTO/RPO targets, capacity planning, and observability defaults
• Cost and performance. Establish patterns for bin-packing, right-sizing, and egress tracking. Partner with FinOps on runtime and networking spend, and review workloads with teams against those patterns
• Architecture review and enablement. Host design reviews, write ADRs, expand the standards library, and run structured POCs of new technologies and vendor offerings as part of the technology-lifecycle and procurement process
