Key Responsibilities
- Lead the design and implementation of robust, scalable, highly available, and cost-efficient cloud infrastructure across both global and regional cloud environment (AWS).
- Develop and implement standardized cloud Landing Zone architecture, including enterprise governance models, network topologies, logging, monitoring, and access controls in alignment with global infrastructure compliance requirements.
Promote adoption of the Well-Architected Framework to ensure systems meet key principles of performance, security, cost-efficiency, reliability, and operational excellence.
- Contribute to the Global Cloud Center of Excellence (CCoE) by delivering architecture standards, service catalogs, automation templates, and training materials.
Mentor teams to strengthen cloud-native capabilities through knowledge sharing sessions, communities of practice, and contributions to open-source initiatives.
Champion Site Reliability Engineering (SRE) by defining and driving the implementation of SLIs, SLOs, and SLAs to enhance availability and operational efficiency.
- Spearhead Infrastructure as Code (IaC) initiatives by developing standardized and reusable modules using tools such as Terraform, OpenTofu, and CloudFormation, integrated with source control systems like GitHub or Bitbucket.
- Provide hands-on leadership in implementing serverless and DevOps solutions, including container orchestration (ECS, EKS), service mesh, microservices, and event-driven architectures.
Support cloud-native modernization and migration efforts by integrating functions such as Lambda or equivalent technologies.
Optimize container images for security and efficiency, integrate them with CI/CD pipelines, and configure load balancing and service discovery.
Partner with DevOps teams to implement automated, version-controlled deployment and rapid rollback processes.
- Architect and implement cloud security frameworks, including identity and access management, network segmentation, encryption strategies, and compliance auditing aligned with enterprise security requirements.
- Formulate and drive cloud cost optimization strategies by leveraging tools such as Cost Explorer, tagging standards, and usage-based purchasing options.
Actively participate in strategic planning and architecture review sessions to ensure alignment between cloud solutions, business priorities, and technology roadmaps.
- Collaborate across product, engineering, operations, and security teams to ensure successful implementation of architectural solutions.
Engage in tool selection and proof-of-concept activities to assess suitability and alignment with platform goals.
- Develop automation scripts (e.g., using Python and Boto3) to streamline resource management and operational workflows.
Implement custom resource handlers and build monitoring and alerting solutions leveraging cloud-native or third-party tools.
- Establish and maintain a comprehensive cloud architecture knowledge base and documentation system to support knowledge sharing and technical enablement across teams.
- Define and maintain standard operating procedures (SOPs) and automate operational tasks to improve system stability, efficiency, and incident response capabilities.
- Design and implement Generative AI (GenAI) solutions using cloud-based large language models.
Optimize models for business-specific use cases, implement responsible AI practices including guardrails and compliance controls, and apply prompt engineering for performance.
Develop Retrieval-Augmented Generation (RAG) architectures using native cloud services.
