Working closely with customer architects and stakeholders, delivery teams, platform administrators and Cloudera, the Senior Data Architect provides architecture direction, platform sizing, workload optimisation and technical leadership. The role also builds the practice by mentoring engineers and administrators and creating reference architectures, tuning playbooks and sizing tools. The position is Senior / Lead level, with a flexible location that is not limited to KSA.
Responsibilities:
Data Architecture
- Design end-to-end data architectures covering ingestion, storage, processing, serving and governance layers for analytics and AI use cases.
- Define data models, lakehouse layering, table formats, and data lifecycle and retention strategies.
- Make sound technology choices and trade-offs, including batch vs streaming, lake vs warehouse, and on-prem vs hybrid.
- Set architecture standards, patterns and data contracts that delivery teams follow.
Cloudera Platform & Workload Optimisation
- Architect and size Cloudera Data Platform environments (CDP Private Cloud Base and Data Services), including topology, capacity and HA.
- 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.
- Present to customer architects and stakeholders, and act as the technical counterpart to Cloudera.
Practice Building
- Mentor engineers and administrators.
- Build reference architectures, tuning playbooks and sizing tools.
Success in the First 12 Months:
- Is the named architect on all active Cloudera engagements.
- Delivers measurable workload performance improvements for at least one customer platform.
