The Cloud Database Migration Engineer is responsible for planning, executing, and validating large-scale database migrations from Oracle to PostgreSQL, with a primary focus on cloud-based implementations on Google Cloud Platform (Google Cloud Platform). This role requires deep technical expertise in relational databases, cloud-native architectures, and data migration methodologies, along with the ability to collaborate closely with application, infrastructure, and security teams to ensure successful outcomes.
The ideal candidate has hands-on experience modernizing legacy Oracle environments and re-platforming them to PostgreSQL in the cloud, with a strong emphasis on performance, security, reliability, and operational excellence.
Key Responsibilities
- Lead end-to-end database migration initiatives from Oracle to PostgreSQL, including assessment, design, execution, validation, and post-migration optimization.
- Design and implement PostgreSQL architectures on Google Cloud Platform, leveraging services such as Cloud SQL for PostgreSQL and related Google Cloud Platform-native tooling.
- Analyze existing Oracle schemas, PL/SQL, stored procedures, triggers, and packages; refactor or re-engineer database logic to be compatible with PostgreSQL.
- Develop and execute migration strategies, including schema conversion, data transformation, and cutover planning, while minimizing downtime and risk.
- Utilize and, where appropriate, customize migration tools and frameworks (e.g., ora2pg, DMS-style tooling, custom scripts).
- Collaborate with application development teams to remediate SQL and application-level dependencies impacted by the migration.
- Optimize PostgreSQL performance, indexing strategies, query execution plans, and connection management in a cloud environment.
- Implement security best practices, including encryption, access controls, auditing, and compliance alignment within Google Cloud Platform.
- Establish backup, recovery, high availability, and disaster recovery strategies for PostgreSQL workloads.
- Produce clear, maintainable technical documentation covering architecture, migration steps, and operational procedures.
- Provide post-migration support and knowledge transfer to operations and support teams.
Required Qualifications
- Bachelor s degree in Computer Science, Engineering, or a related technical discipline, or equivalent professional experience.
- 8+ years of experience working with enterprise relational databases, including significant hands-on experience with Oracle.
- Proven experience migrating Oracle databases to PostgreSQL in production environments.
- Strong knowledge of PostgreSQL internals, including query optimization, indexing, vacuuming, and replication.
- Experience deploying and managing PostgreSQL in Google Cloud Platform environments.
- Deep understanding of SQL dialect differences and migration challenges between Oracle and PostgreSQL.
- Experience refactoring PL/SQL to PostgreSQL-compatible procedural languages (e.g., PL/pgSQL).
- Familiarity with CI/CD pipelines and Infrastructure-as-Code concepts as they relate to database deployments.
- Strong troubleshooting, analytical, and problem-solving skills.
- Excellent written and verbal communication skills, with the ability to work effectively across technical teams.
Preferred Qualifications
- Hands-on experience with Google Cloud Platform services such as Cloud SQL, Compute Engine, Cloud Storage, VPC, IAM, and monitoring/logging tools.
- Experience with high-availability PostgreSQL architectures and read-replica strategies.
- Knowledge of containerized or Kubernetes-based PostgreSQL deployments.
- Experience in regulated or compliance-driven environments.
- Relevant cloud or database certifications (e.g., Google Cloud Professional, PostgreSQL, Oracle).
- Experience with open-source monitoring tools such as Prometheus & Grafana.
