Senior Database Migration Engineer (Secret Clearance)

Migration Assessment, Planning & Execution

• Lead end-to-end database migration activities including discovery, assessment, planning, schema conversion, data movement, validation, cutover, rollback planning, and post-migration stabilization.

• Assess legacy database platforms, schemas, data volumes, stored procedures, functions, triggers, indexes, interfaces, application dependencies, security controls, and performance requirements.

• Develop migration strategies, technical plans, schedules, risk assessments, source-to-target mappings, validation criteria, cutover procedures, rollback procedures, and operational runbooks.

• Lead migration of legacy relational databases to approved AWS managed database platforms, including Amazon Aurora PostgreSQL or Aurora MySQL where implemented.

• Use AWS Database Migration Service, AWS Schema Conversion Tool, native database utilities, and custom scripts, or comparable approved tools, to support full-load, incremental, change-data-capture, and low-downtime migration approaches. Database Conversion, Compatibility & Performance

• Convert and remediate database schemas, data types, stored procedures, functions, triggers, sequences, indexes, queries, and proprietary database features for target-platform compatibility.

• Analyze and remediate application, ETL, BI, API, and interface dependencies affected by database-platform changes, coordinating required code and query changes with the applicable development teams.

• Develop and optimize SQL queries, views, functions, stored procedures, indexes, and other database objects supporting application and reporting requirements.

• Analyze execution plans, workloads, locks, connections, database metrics, and resource utilization to resolve performance and scalability issues.

• Define database-layer requirements for availability, resiliency, replication, backup, recovery, failover, and performance within the approved IGC cloud architecture. Validation, Automation & Secure Delivery

• Develop and execute migration-validation and reconciliation procedures to verify record counts, data relationships, business rules, transformations, calculations, referential integrity, completeness, accuracy, and functional equivalence between source and target platforms.

• Identify data-quality issues and coordinate cleansing, correction, exception handling, and remediation activities with the appropriate data owners and technical teams.

• Develop database and migration automation using SQL, Python, Bash, PowerShell, Liquibase, Flyway, or comparable technologies.

• Integrate database changes, migration scripts, validation routines, and deployment controls into established GitLab CI/CD and configuration-management processes.

• Implement database-specific security controls including least privilege, encryption, secrets management, logging, auditing, secure configuration, vulnerability remediation, and applicable STIG/RMF evidence. Documentation & Technical Leadership

• Prepare and maintain database architecture diagrams, data models, data dictionaries, source-to-target mappings, configuration documentation, migration reports, cutover documentation, and operational procedures.

• Provide technical leadership and mentoring to database administrators, developers, cloud engineers, and migration team members.

• Collaborate with application developers, ETL/data engineers, BI developers, cloud/DevSecOps engineers, cybersecurity personnel, testers, functional analysts, operations staff, and Government stakeholders.

• Eight (8+) or more years of experience in database engineering, database administration, database development, data architecture, or database migration.

• Demonstrated experience leading complex enterprise database migrations from assessment through production cutover and stabilization.

• Hands-on experience with Amazon Aurora PostgreSQL, Aurora MySQL, Amazon RDS, or comparable managed relational database services.

• Experience migrating Oracle, PostgreSQL, MySQL, SQL Server, or comparable enterprise relational databases to cloud-managed database platforms.

• Experience with AWS Database Migration Service, AWS Schema Conversion Tool, native database utilities, or comparable migration technologies.

• Advanced SQL and database-development skills including schemas, stored procedures, functions, triggers, views, indexing, and query optimization.

• Experience converting schemas and remediating incompatible data types, queries, procedural code, and application dependencies.

• Experience developing migration validation, reconciliation, and data-quality controls.

• Experience with database performance tuning, backup, recovery, replication, high availability, and production stabilization.

• Experience scripting database and migration activities using SQL, Python, Bash, PowerShell, or a comparable language.

• Experience using Git and automated database deployment or CI/CD processes.

• Knowledge of database security, access control, encryption, auditing, secure configuration, and vulnerability remediation.

• Strong technical leadership, troubleshooting, documentation, and stakeholder-communication skills.

• Active Secret security clearance or the ability to obtain and maintain one, as required by assigned duties and contract requirements. Education / Workforce Qualification

• A bachelor’s degree in Computer Science, Cybersecurity, Data Science, Software Engineering, Information Technology, Information Systems, or a related software-engineering discipline; or

• One of the following current certifications: Certified Cloud Security Professional (CCSP), CyberSec First Responder (CFR), Federal IT Security Professional-Manager (FITSP-M), GIAC Security Essentials Certification (GSEC), CompTIA Security+, or Systems Security Certified Practitioner (SSCP). Preferred Qualifications

• Experience supporting USTRANSCOM, Department of Defense logistics, or another mission-critical federal system.

• Experience migrating large or highly available databases with minimal downtime using change-data capture, replication, blue-green, or phased migration techniques.

• Experience with Oracle and PostgreSQL/Aurora modernization; familiarity with Teradata or other large-scale enterprise data-warehouse platforms is beneficial where applicable.

• Experience supporting analytics or BI platforms, including Apache Superset, using migrated relational data sources.

• Familiarity with containerized application environments and infrastructure-as-code processes used by cloud/DevSecOps teams.

• AWS, PostgreSQL, Oracle, Microsoft, Security+, or related database/cloud certifications. Work Location

Hybrid. Remote work may be authorized consistent with program requirements. Personnel must be available for required on-site migration planning, testing, cutover, classified-system access, technical reviews, or meetings at Scott AFB, Illinois.
