We are looking for a Data Engineer with strong hands-on experience in HBase, Amazon EMR, Hadoop, and Spark to support a production data platform modernization and migration program.

The role will focus on migrating and modernizing distributed data platforms while maintaining application compatibility, data integrity, performance, and operational stability. The ideal candidate must have real production experience operating and migrating HBase/EMR environments, not only experience with Spark, Databricks, or ETL development.

The engineer will participate in migration planning, cluster-level troubleshooting, data validation, snapshot/restore activities, cutover, rollback, and post-migration verification.

Responsibilities

Design and execute migration and modernization activities for HBase, EMR, Hadoop, and Spark environments.

Support production migration of HBase/EMR workloads across environments.

Perform cluster-level troubleshooting and resolve performance, availability, and compatibility issues.

Plan and execute HBase snapshots, restore, and migration activities.

Validate migrated data using row/region counts, checksums, reconciliation, application behavior, and other appropriate validation methods.

Support HBase data movement using relevant migration mechanisms such as Snapshot/ExportSnapshot/HFile.

Analyze dependencies between HBase, Spark, Hadoop, applications, and supporting platform components.

Support EMR version upgrades and platform modernization.

Participate in production cutovers,



maintenance windows, rollback planning, and post-cutover validation.

Troubleshoot migration issues involving data integrity, cluster configuration, application connectivity, performance, and compatibility.

Work with Backend, Cloud, Architect, DevSecOps, Security, and QA teams to resolve cross-platform dependencies.

Support data validation and reconciliation between legacy and target environments.

Document migration procedures, validation results, issues, resolutions, and operational runbooks.

Contribute to automation and repeatable processes for migration and validation activities.
