Role description

ABOUT THE ROLE

In this role, you will drive a critical migration of AWS data pipelines from HDF5 files to Parquet, made available via open table formats such as Apache Iceberg and Delta Lake, 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.

RESPONSIBILITIES

  • Develop robust, production-quality code using modern C++ (17+) and Python
  • Work within the team to migrate existing parsing processes from HDF5-based pipelines to the new Parquet and Iceberg-based data pipeline
  • Deliver migration changes with a strong emphasis on simplicity, performance, reliability, and maintainability
  • Ensure that existing data delivery channels and downstream systems continue to function correctly throughout the migration
  • Analyse and improve existing C++ parsers (feed handlers) and the pipelines in which they operate, including performance and reliability improvements
  • Use Python and relevant data-processing libraries and tooling to support data retrieval, transformation, analytics, and validation where appropriate
  • Troubleshoot and resolve technical, performance, and data-related issues within distributed AWS-based data pipelines
  • Contribute to second-line support of daily parsing processes and associated data as part of the wider development team
  • Leverage AI-assisted coding tools where appropriate while maintaining full ownership of code quality, consistency, and functional correctness

REQUIREMENTS

  • Strong commercial experience with modern C++ (17+) and developing production-level, well-tested systems
  • Commercial experience with Python development
  • Strong experience developing and troubleshooting software in Linux environments
  • Experience with data processing pipelines and working with large datasets
  • Experience with system or data migrations, including maintaining end-to-end functionality throughout the migration
  • Upper-Intermediate English level or higher
  • Experience with AWS, particularly Amazon S3 and AWS Glue Data Catalog (nice-to -have)
  • Experience with Apache Iceberg and PyIceberg (as a plus)
  • Experience with Python data-processing libraries such as Pandas, Polars, or Apache Spark (as an advantage)
