Core Responsibilities

Primary Functions

  • Develop and maintain the enterprise cloud strategy, reference architectures, and target-state roadmaps that align with business goals, regulatory requirements, and cost objectives across public, private, and hybrid cloud environments.
  • Lead architecture design for large-scale cloud migration programs, including assessment of legacy systems, migration patterns (rehost, refactor, replatform, rebuild), risk analyses, and phasing to minimize business disruption.
  • Define and enforce cloud governance models, guardrails, tagging standards, and account/landing zone patterns to ensure consistent security, compliance, and operational practices across multi-account and multi-cloud landscapes.
  • Design secure identity, access management, and authentication/authorization architectures (IAM, SSO, RBAC, policy as code) to protect enterprise resources and enable least-privilege access.
  • Create and evangelize reusable reference architectures and blueprints for cloud-native services (microservices, serverless, containers) that accelerate developer productivity while maintaining resiliency and operability.
  • Architect and validate infrastructure-as-code (IaC) frameworks and pipelines (Terraform, CloudFormation, Pulumi) that enable repeatable, auditable, and automated provisioning for platforms and applications.
  • Partner with security, compliance, and legal teams to embed security-by-design into cloud architectures, including threat modeling, data protection, encryption, key management, and incident response readiness.
  • Drive cross-functional reviews and architecture governance boards, providing technical leadership, risk mitigation plans, and approval criteria for cloud solutions and third-party cloud services.
  • Define cloud cost management and FinOps strategies including budgeting, tagging, rightsizing, reserved instance/commitment planning, and ongoing cost visibility to optimize cloud spend.
  • Design and operationalize robust observability, monitoring, and logging strategies (metrics, tracing, centralized logs, alerts, SLIs/SLOs) so teams can measure, troubleshoot, and continuously improve system reliability.
  • Lead the selection and adoption of container orchestration and platform technologies (Kubernetes, OpenShift, EKS/AKS/GKE), including platform hardening, multi-cluster strategy, and increasing developer self-service.
  • Evaluate and recommend cloud-managed services (databases, analytics, messaging, ML) and integration patterns to reduce undifferentiated heavy lifting while controlling vendor lock-in and interoperability risks.
  • Define networking and connectivity architectures (VPC/VNet design, Transit Gateway, VPN, Direct Connect/ExpressRoute, service mesh) that provide secure, low-latency, and cost-effective inter-region and on-prem connectivity.
  • Create migration playbooks, runbooks, and operational runbooks for cutover, rollback, DR, and business continuity planning tied to cloud transformation initiatives.
  • Mentor and enable engineering teams through architecture reviews, technical coaching, and workshops to ensure consistent adoption of cloud best practices and platform patterns.
  • Establish measurable architecture KPIs and success criteria (time-to-market, cost savings, uptime, incident reduction) and report outcomes to executive leadership to demonstrate cloud program ROI.
  • Assess and drive modernization of legacy data platforms by defining architecture for data lakes/warehouses, streaming pipelines, and analytics platforms in the cloud, ensuring data governance and lineage.
  • Drive vendor and third-party evaluations for cloud tooling, security products, and managed services; negotiate technical contracts and ensure SLA/operational compatibility with enterprise needs.
  • Lead proof-of-concepts and pilots for emerging cloud technologies (serverless, edge computing, AI/ML platforms), create TCO analyses, and recommend adoption strategies aligned to business value.
  • Ensure compliance with industry and regulatory frameworks (PCI, HIPAA, SOC2, GDPR) through architectural controls, encryption strategies, and data residency planning.
  • Collaborate with product and portfolio managers to translate business capabilities into a cohesive set of platform capabilities and APIs that drive reuse, faster delivery, and consistent user experiences.
  • Facilitate cross-team incident reviews and blameless postmortems to identify architectural changes and process improvements that reduce recurrence and improve platform resilience.

Secondary Functions

  • Support architecture-related RFP responses, technical due diligence, and acquisition integrations to ensure coherent cloud footprint and technical fit.
  • Provide periodic architecture briefings and executive-ready summaries that articulate tradeoffs, risks, and recommendations for cloud investments.
  • Contribute to the organization’s cloud skills roadmap by identifying training needs, running architect office hours, and running workshops to uplift engineering capabilities.
  • Collaborate with procurement and legal to define security and architecture-related contractual requirements for cloud service providers, including shared responsibility models.
  • Assist platform and DevOps teams with pipeline architecture, CI/CD best practices, and environment promotion strategies to improve release velocity and quality.
  • Participate in industry forums and maintain knowledge of cloud innovation, competitive offerings, and ecosystem changes that impact enterprise architecture choices.
  • Support proof-of-value initiatives and iterate architecture based on real-world telemetry and feedback from operations and development teams.
  • Help define data classification, retention, and encryption policies across cloud services to ensure consistent handling of sensitive information.
