• Solid foundations in probability and statistics
• Strong Python for research workflows (working with large datasets)

CDE: environment setup, job execution operations, quotas, scheduling/monitoring, dependency/runtime management, and troubleshooting. 3. Cloudera AI (CAI): workspace setup, runtimes, user onboarding/support, and alignment with enterprise security controls.
• Own day-2 operations for Data Services: upgrades, scaling, backups (where applicable), monitoring/alerting, and incident/RCA.

High Availability (HA) & Resilience

• Implement and maintain HA for critical services (as applicable): NameNode HA, ResourceManager HA, HiveServer2 HA, and resilient Kafka/Zookeeper patterns.
• Validate failover behavior and maintain operational runbooks and SOPs.

Security: Kerberos, Auto-TLS, Ranger, KMS/HSM

• Lead Kerberos enablement and ongoing administration (principals, keytabs lifecycle, renewals, troubleshooting authentication issues).
• Enable and manage TLS at scale, including Cloudera Auto-TLS, certificate lifecycle management (keystores/truststores), trust chains, and secure service-to-service communications.
• Administer Ranger access controls (resource-based and tag-based policies), auditing, and ecosystem integrations; support governance via Atlas (as needed).
• Install/configure and operate Ranger KMS and HDFS Transparent Data Encryption (TDE) (encryption zones, key rotation, access policies, audits).
• Integrate Ranger KMS with external HSM / enterprise KMS (vendor-agnostic), ensuring secure key custody, compliance alignment, and auditability.

Operations & Automation

• Operate monitoring and alerting (Cloudera Manager and enterprise tools), manage incidents and RCAs, and drive permanent fixes.
• Maintain documentation, runbooks, change management, and standard maintenance processes.
• Automate repeatable operational tasks using Bash/Python (and optionally Ansible/Terraform where applicable).
