Role overview
We are seeking a highly skilled Data Architect – Performance Optimization Expert with deep expertise in SQL, PySpark, and Databricks performance tuning. This role focuses on handling large-scale data workloads, optimizing complex transformations, and designing highly efficient data pipelines within a Medallion Architecture (Bronze, Silver, Gold layers).
The ideal candidate will bring strong hands-on experience in query optimization, partitioning strategies, clustering, and managing high-volume read/write operations using modern Lakehouse technologies such as Delta Lake and Apache Iceberg.
Key responsibilities:
1.Data pipeline development and optimization
Design, develop, and optimize scalable data pipelines in Databricks using PySpark and SQL .
Optimize complex SQL queries and Spark jobs for performance, cost, and scalability.
Handle large-scale transformations and complex joins across TB–PB scale datasets.
2.Architecture and data modeling
Implement and maintain Medallion Architecture (Bronze, Silver, Gold layers).
Apply strong data modeling practices for efficient data processing and access.
Build reusable frameworks and enforce best practices for performance optimization.
3.Performance engineering
Define and enforce partitioning, bucketing, and clustering strategies (including Z-ordering).
Optimize read and write performance for large datasets.
Tune Spark jobs using techniques such as:
Broadcast joins
Caching and persistence
Adaptive Query Execution (AQE)
Shuffle optimization
Analyze execution plans (Spark UI, DAGs) and apply cost-based optimization techniques.
Address data skew, large joins and shuffle-intensive workloads.
4.Databricks and lakehouse optimization
Work extensively with Delta Lake and Apache Iceberg tables.
Optimize cluster configurations (autoscaling, instance types, memory tuning).
Manage Databricks jobs, workflows, and production pipelines.
Ensure efficient file sizing, compaction, and storage optimization.
5.Quality, reliability and troubleshooting
Identify performance bottlenecks and implement optimization strategies.
Ensure data quality, consistency, and reliability across pipelines.
Debug complex data processing and system performance issues.
Collaboration & Stakeholder Engagement.
Collaborate with Analytics, BI, Product, and DevOps teams.
Translate business requirements into scalable and optimized data solutions.
Required skills and experience:
Core technical skills
