  • Define and implement infrastructure-as-code (IaC) standards and pipelines using Terraform, CloudFormation, ARM templates or equivalent tooling to support reproducible, auditable, and versioned cloud deployments.
  • Architect containerized application platforms using Docker and Kubernetes (EKS/AKS/GKE) including cluster sizing, multi-tenancy patterns, namespace strategy, and operator/controller adoption to support developer productivity.
  • Drive API design and governance, including REST/GraphQL contract design, API Gateway configuration, authentication/authorization patterns, throttling, versioning, and observability.
  • Build and enforce cloud security architecture: define network segmentation (VPC/VNet design), identity and access management (IAM) policies, encryption at rest/in transit, secrets management, and secure connectivity for hybrid environments.
  • Establish CI/CD pipelines and release automation best practices (Jenkins, GitLab CI, GitHub Actions, Azure DevOps) to enable continuous delivery, blue/green and canary deployments, and rollback strategies.
  • Create cost-optimization strategies and governance to monitor, predict, and reduce cloud spend, including rightsizing, reserved/commitment purchases, and architectural trade-offs between cost and performance.
  • Lead application migration projects from on-premises or legacy cloud setups to cloud-native architectures, owning migration plans, cutover approaches, data migration strategies, and rollback contingencies.
  • Define and implement observability and monitoring architecture (metrics, tracing, logging) using Prometheus/Grafana, OpenTelemetry, ELK/EFK, Datadog or equivalent to ensure actionable alerting and SLO/SLI adherence.
  • Design resilient disaster recovery (DR) and backup strategies, including multi-region failover, RTO/RPO definitions, automated recovery playbooks, and regular DR testing.
  • Evaluate and select cloud services, third-party tools, and vendors; conduct POCs and create trade-off analyses to recommend best-fit solutions for the organization’s technical and business constraints.
  • Implement event-driven patterns (Kafka, Pub/Sub, Event Grid) and stream processing architectures for high-throughput, low-latency systems, including schema evolution and retention policies.
  • Define data architectures for cloud-native applications, selecting appropriate storage patterns (relational, NoSQL, object storage, caching) and ensuring data consistency, security, and performance.
  • Establish governance, patterns, and guardrails (landing zone, tagging, network baseline) to accelerate delivery while maintaining compliance (PCI, HIPAA, SOC2) and enterprise standards.
  • Mentor and coach engineering teams in cloud best practices, design patterns, and operational excellence; conduct workshops, brown-bags, and architecture training sessions.
  • Collaborate with security, compliance, and legal teams to incorporate regulatory requirements into architecture decisions and to perform threat modeling and risk assessments.
  • Work with product management and business stakeholders to convert business capabilities into technical roadmaps, prioritizing work that maximizes customer value and reduces technical debt.
  • Create architecture artifacts (diagrams, decision records, runbooks) and maintain a living architecture repository to enable knowledge transfer and facilitate onboarding.
  • Drive platform engineering initiatives to provide self-service developer platforms and abstractions that reduce cognitive load, accelerate delivery, and standardize operations across teams.
  • Participate in incident management and post-incident reviews to identify root causes, implement architecture-level fixes, and improve system resiliency and runbook completeness.
  • Advocate for and implement infrastructure automation, testing (unit, integration, performance), and shift-left security practices to improve delivery velocity and reduce production risk.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis.
  • Contribute to the organization's data strategy and roadmap.
  • Collaborate with business units to translate data needs into engineering requirements.
  • Participate in sprint planning and agile ceremonies within the data engineering team.
  • Produce architecture design documents, cost estimates, and technology evaluations to support budgeting and capital planning.
  • Assist procurement and vendor negotiations with technical evaluations and RFP responses.
  • Provide on-call architectural support during major releases, migrations, or critical incidents.
  • Participate in hiring, interviewing, and building a high-performing cloud architecture discipline within the organization.
  • Maintain awareness of industry trends, emerging cloud technologies, and open-source projects; recommend innovation opportunities that align with business goals.
