Senior Data Engineer

Key Responsibilities

Lead the Architectural Redesign : Analyze and re-architect the existing highly-normalized PostgreSQL database, driving the transition to a modern, high-performance analytical data model.

Optimize for Performance : Redesign schemas, balancing normalization with analytical read efficiency. Strategically apply denormalization, materialized views, and dynamic queries to support high-speed data access.

Scale Data Delivery : Introduce advanced PostgreSQL strategies including robust indexing, partitioning, caching, and replication to ensure high-throughput and low-latency access for client-facing APIs and internal tools.

Data Pipeline Excellence : Design, implement, and maintain scalable data pipelines and ETL / ELT frameworks across distributed systems to ensure data reliability and freshness.

Technical Leadership : Act as a subject matter expert, guiding the engineering team on best practices for data modeling, query optimization, and architectural decisions.
