• Diagnose and optimise workloads on Cloudera, including Spark, Hive and Impala query tuning, YARN resource management and queueing, file layout, partitioning and compaction, and contention under mixed workloads.
• Make ingestion and processing pipelines more stable and faster, and bring latency and SLAs under control.
• Plan capacity and growth, and decide when to tune, re-architect or scale out.
• Guide platform security and governance design (Kerberos, Ranger, Atlas) with the admin team.
• Give technical direction on upgrades and migrations.

Presales & Customer Leadership

• Write the architecture and Cloudera sections of proposals, size licences and infrastructure, and estimate effort.
• Run platform health checks and performance assessments as client engagements.
