Identity and access management
Manage least-privilege IAM access and IAM Identity Center integration with Microsoft Entra ID. Coordinate identity lifecycles, access reviews, authentication and privileged or emergency access controls with identity owners, favoring temporary credentials and removing stale access.
Networking, connectivity and edge services
Operate approved AWS networks, private endpoints, hybrid and cross-region connectivity, maintaining secure routing and access controls.
Manage DNS, edge delivery and load balancing; troubleshoot connectivity, health and performance, and review availability and cost with network teams.
Security and compliance operations
Implement approved security baselines, threat detection, vulnerability management, configuration compliance, edge protection and secret rotation, retaining audit evidence. Coordinate authorized testing and approved remediation with Security, escalating exceptions for risk decisions.
PKI and certificate lifecycle
Manage certificate issuance, deployment, renewal and expiry monitoring across supported AWS services. Support private CA integration, mutual TLS, revocation and key protection with PKI and Security owners, observing service-specific requirements.
Landing zone and platform standards
Operate Control Tower landing zones, account enrollment and approved infrastructure-as-code customizations. Maintain versioned Terraform modules, a module registry, secure locked state and platform standards; test changes, address drift and evolve designs with architecture owners.
Infrastructure automation and CI/CD
Maintain secure infrastructure pipelines, Terraform code and automation with version control, peer review, testing and deployment evidence. Assess impact, dependencies and rollback, preserving approvals and segregation of duties.
Compute and operating-system administration
Manage EC2 capacity, scaling, quotas and hardened images, including Linux and Windows configuration, patching and vulnerability remediation with tested rollback.
Container platforms and registries
Operate ECS/Fargate, EKS and ECR, managing capacity, scaling, permissions, registry lifecycle and replication, and tested upgrades. Coordinate secure diagnostics, image remediation and workload troubleshooting with developers.
Storage and data protection controls
Administer object, block and file storage, archives and approved hybrid access, managing permissions, encryption, capacity, performance and recovery. Apply lifecycle, replication, immutability, retention and deletion controls agreed with data and compliance owners, considering retrieval time and cost.
Managed database platform operations
Operate approved managed databases, caches and migration services, maintaining availability, capacity, patching, connectivity, monitoring and recovery. Coordinate upgrades, performance investigations and replication health with DBAs and application owners, who retain schema, query, data correctness and migration acceptance decisions.
Backup and disaster recovery
Maintain centralized backups, retention, protected vaults and supported cross-account or cross-region copies, resolving failures and documenting recovery dependencies. Test approved resilience and disaster-recovery plans against agreed RTO/RPO targets with service owners, recording evidence and corrective actions.
Cost, capacity and continuous improvement
Monitor costs, anomalies, budgets and allocation tags with FinOps; validate right-sizing and approved resource cleanup without degrading service. Provide utilization evidence for authorized commitment purchases and contribute to Well-Architected reviews and continuous improvement.
Stakeholder and supplier engagement
Gather operational requirements, contribute to architecture reviews and coordinate technical issues with AWS Support and suppliers. Provide evidence for commercial discussions, leaving negotiation, contracts and spending commitments to authorized decision-makers.
Service operations and operational leadership
Maintain actionable monitoring, audit logging and alerts against agreed service objectives; lead or support incident restoration, communication and escalation, preserving evidence, coordinating with Security and tracking root-cause and post-incident actions.
Deliver risk-assessed, approved changes with validation and rollback; maintain inventories, configuration records, diagrams, procedures and tested runbooks, ensure operationally ready handovers, mentor colleagues, automate safely and escalate technical debt or risks beyond delegated authority.
