Job Description:
Project Background:
As part of a large-scale digital transformation led by Kyndryl, the client is undertaking two critical cloud migration workstreams:
• Migration of on-premises Kubernetes workloads and associated databases (Jetstream application) to Azure Kubernetes Service (AKS) and Azure Managed Databases
This role focuses on Workstream where , supporting the migration of on-premises databases such as PostgreSQL, MySQL, and MongoDB to Azure native managed database platforms like Azure PostgreSQL, Azure SQL Managed Instance, and Cosmos DB.

Role Overview:
We are seeking an experienced Database SME with deep technical expertise in relational and NoSQL databases, who will lead and support the migration of on-prem PostgreSQL, MySQL, and MongoDB workloads to Azure-native managed database services. The candidate should have experience in end-to-end database migration lifecycle, from assessment, compatibility checks, performance tuning, HA/DR design to validation and cutover.
________________________________________
Key Responsibilities:
Discovery & Assessment
• Conduct discovery of the existing on-premises PostgreSQL, MySQL, and MongoDB environments.
• Evaluate schema designs, data volumes, configuration, performance characteristics, and HA/DR setups.
• Assess compatibility of source DBs with Azure managed offerings (Azure PostgreSQL, Azure SQL MI, Cosmos DB).
• Participate in creating inventory, complexity mapping, and readiness reports.
Design & Planning
• Define target architecture for each database platform on Azure, considering:
o Performance (vCores, IOPS, throughput)
o Availability Zones / Geo-replication
o Backup, retention, recovery
o Access control, firewall, identity integration (AAD where applicable)
• Recommend appropriate Azure services:
o Azure PostgreSQL Flexible Server
o Azure SQL Managed Instance (for workloads needing SQL Server compatibility)
o Cosmos DB with MongoDB API for NoSQL workloads
• Document migration design plans including rollback strategy and DR configuration.
Migration Execution
• Perform or support schema migration using tools like Azure DMS, pg_dump/pg_restore, mysqldump, mongoexport/import, custom scripts.
• Conduct data transfer in phased or cutover model (offline/online replication).
• Validate data integrity, consistency, and performance post-migration.
• Support database performance tuning and troubleshooting during and post-migration.
Operationalization & Handover
• Implement and test backup, restore, and HA/DR configurations for managed databases.
• Configure monitoring and alerting using Azure Monitor, Log Analytics, and diagnostic settings.
• Develop runbooks, tuning guidelines, and capacity plans.
• Conduct knowledge transfer sessions with the client's operations team.

Required Skills & Experience:
• 8+ years of experience in relational and NoSQL database administration and architecture.
• Minimum 3+ years of experience with Azure-managed database services, including:
o Azure PostgreSQL (Single Server/Flexible Server)
o Azure SQL Managed Instance
o Cosmos DB (MongoDB API or Core SQL)
• Proven track record of migrating PostgreSQL, MySQL, and MongoDB from on-prem to Azure.
• Expertise in schema conversion, replication strategies, data migration tools, and cutover planning.
• Strong understanding of HA/DR patterns, backup and retention policies in Azure.
• Deep troubleshooting knowledge including query optimization, slow queries, index design, and IOPS analysis.
• Experience working with Azure-native monitoring tools (Azure Monitor, Metrics, Alerts, Logs).

Nice to Have:
• Experience with DevOps-based database deployment using Azure DevOps Pipelines or GitHub Actions
• Hands-on experience with Terraform or Bicep for provisioning managed databases
• Familiarity with CI/CD for DB schema deployment, versioning tools (e.g., Flyway, Liquibase)
• Knowledge of hybrid connectivity (ExpressRoute, VPN) for online migrations
• Microsoft certification: DP-300 (Administering Relational Databases on Azure)
