Write, review, and approve clean, modular, and highly performant Scala and Python code, enforcing best practices across the team.
Diagnose and resolve complex performance bottlenecks by analyzing Spark DAGs, execution plans, and executor metrics to address issues like data skew, shuffling, and memory management.
Apply advanced optimization techniques for Spark and SQL, including broadcast joins, predicate pushdown, partition pruning, Z-Ordering, and adaptive query execution.
Manage and optimize Databricks workspaces, including Unity Catalog, Delta Live Tables, job clusters, security, governance, and monitoring.
Implement and manage Apache Iceberg or Delta Lake as an enterprise table format, applying knowledge of features such as hidden partitioning, schema evolution, and compaction strategies.
Develop and enforce enterprise data-modelling standards and Lakehouse practices, including medallion architecture (Bronze, Silver, Gold layers).
Lead, mentor, and develop a global team of data engineers, conducting code reviews, architecture reviews, and technical design sessions.
Manage technical priorities, delivery milestones, dependencies, and risks, and collaborate effectively with business stakeholders, product owners, architects, and support teams.
Define and enforce standards for coding, testing, deployment, monitoring, data quality, operational readiness, and production support.
Appropriately assess risk when business decisions are made, demonstrating particular consideration for the firm's reputation and safeguarding Citigroup, its clients and assets, by driving compliance with applicable laws, rules and regulations, adhering to Policy, applying sound ethical judgment regarding personal behavior, conduct and business practices, and escalating, managing and reporting control issues with transparency.
