## Description

In this role, you will drive a critical migration of AWS data pipelines from HDF5 files to Iceberg tables, working with C++, Python, and large datasets to modernize a high-performance data architecture. Our Client is a London-based leader in harmonized historical order book and market data, powering advanced trading analytics and AI-driven insights. You'll collaborate in a focused team to deliver scalable, efficient data foundations that directly impact global capital markets., * Design and implement new AWS data pipeline components in C++ and Python to switch output from HDF5 files to Iceberg tables, improving efficiency and modernizing the data architecture

 * Own end-to-end migration tasks within the AWS-based data pipelines, ensuring scalable handling of large datasets and minimizing risk to existing data flows and performance
 * Collaborate closely with a small, focused team to coordinate changes across C++ services, Python tooling, and AWS data workflows during the migration from HDF5 to Iceberg
 * Analyze existing C++ logic that generates HDF5 files and refactor or extend it to produce Iceberg tables, maintaining data integrity and schema consistency across large datasets
 * Integrate Python-based utilities and scripts into the AWS data pipelines to support data transformation, validation, and loading of large datasets into Iceberg tables
 * Optimize data processing paths in C++ and Python for large-scale datasets within AWS, aiming to enhance throughput, reliability, and scalability of the new Iceberg-based pipelines
 * Troubleshoot, debug, and resolve issues arising during the transition from HDF5 file generation to Iceberg table creation in AWS, ensuring stable and predictable pipeline behavior
