• Analyze cloud spend and implement cost optimization strategies including right-sizing, Reserved Instances, Savings Plans, and resource lifecycle management
• Build dashboards and reporting tools to provide visibility into infrastructure costs and enable teams to make data-driven decisions
• Build and maintain self-service platforms through automation to increase developer productivity and assure product/service quality
• Troubleshoot and solve problems across AWS infrastructure and application domains; lead incident response and conduct blameless post-mortems
• Design durable and consistent patterns for distributed systems; recommend architecture and process improvements
• Collaborate across multiple functional and technical teams to deliver projects on time and build enterprise-level platforms per the roadmap
• Analyze and resolve complex infrastructure and application deployment issues
• Evaluate emerging technology trends to enable evolving business and operating models
• Facilitate the evaluation and selection of software products, services, and standards; design standard and custom software configurations
• Assess existing platforms to identify deficiencies and improvements; recommend whether to maintain, refresh, or retire products, services, or systems

• Strong experience implementing observability solutions including metrics collection, centralized logging, and distributed tracing (e.g., OpenTelemetry, Jaeger, X-Ray)
• Proven ability to design effective alerting systems with appropriate thresholds, escalation policies, and on-call rotations
• Experience with incident management, root cause analysis, and building automated remediation workflows
• Demonstrated track record of identifying and implementing AWS cost optimization strategies (right-sizing, Reserved Instances, Savings Plans, spot instances, resource scheduling)
• Familiarity with AWS cost management tools (Cost Explorer, Budgets, Cost Allocation Tags, Compute Optimizer)
• Strong Infrastructure-as-Code skills using tools such as Terraform, Ansible, Python, and Shell scripting
• Hands-on experience with containerization and orchestration (e.g., Docker, Kubernetes, AWS EKS, ECS)
• Solid experience in 24x7 production AWS environments, including CI/CD pipelines (Jenkins, GitLab CI, etc.)
• Strong understanding of Site Reliability Engineering principles, SLOs/SLIs/SLAs, error budgets, and chaos engineering
• Linux and Windows server administration
