HDP Administrator / Architect

Role Summary

The HDP Administrator / Architect will provide deep technical expertise in administering and modernizing Hortonworks (HDP) and Cloudera environments as part of enterprise-scale data modernization initiatives powered by NexusOne . This role is responsible for ensuring operational stability, performance, and compliance of existing Hadoop environments, while architecting and supporting the transition toward open-source, cloud-native components (e.g., Spark, Iceberg, Trino, Ranger, DataHub).

This individual must possess hands-on depth in the full Hortonworks stack — from cluster management and security to performance tuning and metadata governance — serving as the technical bridge between legacy and modern data ecosystems.

Core Responsibilities

• Administer, monitor, and optimize Hortonworks Data Platform (HDP) clusters, including HDFS, YARN, Hive, HBase, Oozie, Ranger, Atlas, and Ambari.
• Perform environment maintenance and upgrades — patching, version management, capacity planning, and backup / recovery.
• Ensure platform reliability, high availability, and adherence to enterprise security and compliance requirements.
• Collaborate with Data Engineering and Platform Architecture teams to design migration strategies from HDP / Cloudera to modern open-source frameworks.
• Lead the migration of data, metadata, and security policies from legacy components (e.g., Atlas / Ranger) to DataHub, Iceberg , and modern equivalents.
• Conduct root-cause analysis and resolve complex performance or stability issues across distributed systems.
• Implement and maintain Kerberos, LDAP / SSO integration, and role-based access control (RBAC) policies.
• Document architecture, configurations, and operational runbooks for cluster management and decommissioning.
• Train and mentor engineers in HDP administration, troubleshooting, and modernization best practices.
