• Apply Site Reliability Engineering (SRE) practices, including defining and tracking Service Level Objectives (SLOs), error budgets, and reliability metrics aligned to contract SLAs (e.g., ≥99.9% availability).
• Build and maintain observability across the AWS and Pega environments, including centralized logging, monitoring, and alerting, to enable proactive detection of performance and availability issues.
• Lead incident response and root-cause analysis for production issues, and long-term reliability improvements.
• Automate infrastructure provisioning, configuration, and environment build-out using Infrastructure as Code (e.g., Terraform, CloudFormation, Ansible).
• Design and test Disaster Recovery capability for cloud-based workloads, including backup, failover, and Multi-AZ/Multi-Region resilience.
• Support performance testing and capacity planning to validate the platform's ability to scale to 20,000 concurrent CSR sessions and peak Open Enrollment Period (OEP) volumes.
• Support continuous security monitoring, vulnerability remediation, and Zero Trust alignment across the AWS and Pega environments.
• Partner with the DevOps Lead/Configuration Manager to build and maintain CI/CD pipelines, ensuring automated testing, security scanning, and deployment across all SDLC environments.
• Support cloud connectivity and data movement for the AWS-based data migration pipeline (e.g., AWS Glue, S3, RDS/Aurora PostgreSQL) between legacy Siebel and the modernized CRM.
• Coordinate with the CMS Hybrid Cloud Team on cloud environment provisioning, patching, and lifecycle management activities.
• Manage release coordination and change windows in support of OEP blackout periods and other critical operational periods, minimizing risk of service disruption.
• Collaborate with the Release Train Engineer, Solution Architect, and Agile delivery teams to align infrastructure readiness with sprint and PI planning.
• Support integration of Genesys Cloud CX infrastructure and telephony/chat channels with the modernized CRM environment.
• Continuously identify opportunities to reduce operational toil through automation of repetitive tasks, log analysis, and routine operational activities.
• Document cloud architecture, operational runbooks, and disaster recovery procedures to support the Transition-Out Plan and audit readiness.
• Provide technical mentoring and knowledge-sharing to other engineers on cloud architecture, automation, and reliability engineering best practices.
• Communicate technical status, risks, and dependencies to CMS leadership, and Leidos management.
• Support requirements traceability and technical documentation related to infrastructure and integration architecture.
• Actively participate in planning sessions, requirements gathering activities, design sessions, Agile sessions, and other events supporting the CRM modernization effort.
