Sr Snowflake/DWH/ETL Informatica Consultant

The ideal candidate has built and optimized enterprise-grade analytical platforms, implemented robust CDC frameworks, and supported performance-sensitive financial reporting workloads. The resource will assist with developing reliable, governed, and performant data solutions that enable exposure reporting, factor analysis, time-series risk metrics, stress testing, and performance attribution. This role works closely with business intelligence engineers, data architects, and data scientists. The selected Contractor will be responsible for the following essential activities:

• Implement Snowflake schemas and object lifecycle strategies optimized for risk and

portfolio analytics workloads.

• Develop scalable, dimensional, and time-series data models supporting portfolio

hierarchies, positions, security master integration, exposures, and risk metrics.

• Build robust ELT pipelines using dbt and native Snowflake capabilities, including

Streams, Tasks, and Snowpipe, to support daily and intraday data processing.

• Implement efficient change data capture and incremental processing strategies for

position, pricing, risk, and reference data.

• Develop and maintain high-performance tables, views, and materialized views aligned

with performance-sensitive analytical use cases.

• Lead query performance optimization efforts, including clustering strategy design,

micro-partition awareness, warehouse sizing, caching behavior, and workload management.

• Establish data quality frameworks, including reconciliation controls, completeness

checks, monitoring, and alerting for financial datasets.
