[Hiring] Database Migration Architect @EPAM Systems

Role Description

Our team is in search of a Database Migration Architect to take charge of the database layer within a sizable VMware-to-AWS migration encompassing close to 6,000 virtual machines, rolled out across waves of as many as 600 VMs at a time. This position is responsible for architecting and owning the destination database platforms built on Amazon RDS and Amazon Aurora, mapping out and carrying through database migrations via AWS Database Migration Service, and synchronizing each database wave with VM cutovers managed through AWS Application Migration Service (MGN). The engagement is fully AWS-native, drawing on Amazon RDS, Amazon Aurora, AWS DMS, Amazon VPC, and AWS CloudFormation, all operating inside a multi-account landing zone.

Responsibilities

• Evaluate existing database environments, determine suitable target engines and migration methods, and establish the migration approach for each individual wave.
• Coordinate and carry out both homogeneous and heterogeneous database migrations onto Amazon RDS and Amazon Aurora through AWS DMS, handling full load, change data capture, and cutover stages.
• Confirm the integrity of migrated data along with application connectivity, while establishing rollback plans for every database cutover event.
• Shape target database architecture with attention to availability, backup strategy, security, and cost control, incorporating Multi-AZ setups, encryption, and parameter adjustments.
• Scale database instances and storage appropriately, and optimize performance of migrated systems relative to original source benchmarks.
• Produce database runbooks and transition documentation that equip operations teams to manage the migrated platforms going forward.
• Establish Amazon VPC connectivity along with subnet and security group configurations suited to database workload requirements within the landing zone.
• Synchronize database cutover timing with VM migration waves handled via AWS MGN, keeping applications and their data moving together.
• Develop and sustain AWS CloudFormation templates covering database infrastructure, ensuring uniform provisioning throughout each migration wave.

Qualifications

• At least 8 years of applicable work experience.
• A minimum of 3 years spent in Senior, Lead, Manager, or Owner-level capacities.
• Demonstrated history managing engagements for teams of 20 or more full-time staff members.
• Practical experience with AWS Application Migration Service for managing large-scale virtual machine migration efforts.
• Background applying AWS CloudFormation for infrastructure provisioning and management through code.
• Solid experience using AWS Database Migration Service to plan and carry out database migration projects.
• Strong capability with Amazon RDS for architecting and overseeing relational database environments.
• Comprehensive familiarity with Amazon Web Services and its core cloud infrastructure offerings.
• Experience in DBA functions and cloud migration work, reflecting solid command of database platform administration.
• Professional proficiency in English (C1) and a proactive, accountable approach to problem-solving.

Nice to have

• Background working with AWS Aurora to architect and manage resilient, cloud-native database environments.
• Working knowledge of Amazon VPC for establishing secure, stable network configurations.
• Experience in database performance tuning aimed at improving speed and efficiency following migration.
• Familiarity with VMware vSphere, offering useful context regarding source environments before migration begins.
• Relevant certification, which would be considered a valuable addition to your qualifications.
