- Configure compute, storage, and networking required for migrated workloads
- Support integration with AWS services such as EC2, EBS, EFS, S3, IAM, VPC, ALB/NLB
- Ensure migrated workloads meet performance, availability, and security requirements
Monitoring & Observability
- Enable and configure monitoring and alerting migrated workloads
- Implement AWS native monitoring using CloudWatch metrics, logs, and alarms
- Integrate with enterprise monitoring tools (Prometheus, Grafana, ELK – where applicable)
- Ensure application and infrastructure visibility post‑migration
Backup, DR & Resiliency
- Configure backup strategies for migrated workloads using AWS services
- Support disaster recovery (DR) setup and testing for AWS environments
- Execute and validate DR drills and recovery tests
- Ensure RTO and RPO objectives are met for migrated systems
Configuration & Reliability Enablement
- Ensure server configurations are consistent post‑migration
- Support configuration management using Ansible, Cloud‑Init, or AWS SSM
- Perform post‑migration validation, stabilization, and tuning
- Participate in incident troubleshooting related to migrated workloads
Security & Compliance (Financial Services)
- Implement security controls including IAM roles, security groups, encryption
- Ensure migrated workloads comply with CLIENT security and audit standards
- Work with security teams during risk reviews and compliance checks
Required Skills
Mandatory
- Strong experience in on‑prem to AWS migration
- Hands‑on AWS experience (EC2, VPC, IAM, EBS, S3, CloudWatch)
- Experience with lift‑and‑shift / rehost migrations
- Strong Linux system administration

Soft Skills
- Strong coordination across infra, app, and security teams
- Calm and methodical approach during migrations and cutovers
