Responsibilities:
  • Design, implement, and optimize database objects and complex PL/pgSQL procedures to support regulatory reporting use cases.
  • Build and maintain robust DB dependencies: primary/foreign keys, constraints, triggers, partitions, and scheduled maintenance routines.
  • Own Postgres performance and hygiene: capacity planning, index maintenance, partition strategy, VACUUM/ANALYZE, and systematic tuning using EXPLAIN and pg_stat_statements.
  • Develop, schedule, and operate data pipelines as DAGs (in Airflow): ingestion, transformations, validations, and deliveries to reporting targets.
