  • Develop network and connectivity designs for hybrid/multi-cloud environments (VPC/VNet design, transit hub, VPN/Direct Connect, ExpressRoute, peering, private endpoints) ensuring performance, segmentation, and secure ingress/egress.
  • Build and maintain automated CI/CD pipelines for infrastructure and application delivery (GitOps, Jenkins, GitLab CI, Azure DevOps, AWS CodePipeline), integrating security checks, automated testing, and blue/green or canary deployments.
  • Lead containerization and orchestration initiatives (Docker, Kubernetes, EKS/AKS/GKE), designing cluster topology, multi-tenant isolation, service mesh (Istio/Linkerd), autoscaling, and cost-efficient resource sizing.
  • Establish observability and monitoring architectures (CloudWatch, Prometheus, Grafana, Datadog, Stackdriver) with logging, metrics, tracing, and alerting strategies to meet SLAs and accelerate incident resolution.
  • Define and enforce cloud governance, tagging, organizational policies, guardrails, and landing zone constructs using tools like AWS Organizations, Azure Management Groups, GCP Folders and policy-as-code solutions (OPA, Azure Policy, AWS Config).
  • Optimize cloud spend through rightsizing, reserved/committed use plans, cost allocation, FinOps best practices, and automated scheduling and autoscaling to meet efficiency targets and budget forecasts.
  • Design disaster recovery and business continuity plans (RTO/RPO targets) across regions and availability zones, including automated backups, replication strategies, and failover testing procedures.
  • Drive platform and service selection, evaluate third-party cloud services, SaaS integrations, and managed services to accelerate delivery while controlling vendor risk and cost.
  • Implement data protection and privacy controls for cloud-hosted data (encryption at rest/in transit, key management, data classification, retention policies) to comply with GDPR, HIPAA, PCI-DSS, and other regulations.
  • Lead proof-of-concept (POC) initiatives, pilot new cloud services, and produce technical ROI/feasibility studies to inform product and platform roadmaps.
  • Provide technical leadership and mentoring to engineering teams, set architecture standards, conduct design reviews, and ensure consistent adoption of best practices across squads and domains.
  • Collaborate with product managers, security, compliance, network engineering, and operations to translate business requirements into secure, scalable cloud solutions and prioritize backlog items.
  • Create clear architecture diagrams, runbooks, operational runbooks, and deployment guides to enable platform teams and support effective handover to operations and SRE teams.
  • Establish incident response, post-incident reviews, and continuous improvement loops to reduce recurrence and improve platform reliability and performance.
  • Drive automation of maintenance tasks, lifecycle management, and platform upgrades to reduce toil and improve deployment velocity.
  • Assess and mitigate technical risks, maintain a risk register for cloud initiatives, and ensure architecture decisions include contingency and rollback plans.
  • Lead vendor negotiations and manage relationships with cloud providers and managed service vendors, ensuring service level objectives and contractual protections align with organizational needs.
  • Design and implement API gateway, service mesh, and integration patterns for secure, reliable, and performant service-to-service communication across distributed systems.
  • Champion accessibility, scalability, and latency requirements in architecture decisions and validate designs through capacity planning and load testing.
  • Influence the enterprise cloud roadmap by evangelizing cloud-native patterns, documenting platform strategy, and aligning architecture work with long-term business objectives.

Secondary Functions

  • Support ad-hoc platform health requests and exploratory platform performance analysis to identify bottlenecks and optimization opportunities.
  • Contribute to the organization's cloud strategy, platform roadmap, and standard operating procedures for cloud deployments.
  • Collaborate with business units to translate application and data needs into cloud architecture requirements and backlog items.
  • Participate in sprint planning and agile ceremonies with platform, security, and infrastructure teams to ensure alignment and continuous delivery.
