Senior C++ Software Engineer (Python/Data focus)

ABOUT THE ROLE

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.

RESPONSIBILITIES

  • 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

REQUIREMENTS

  • Strong proficiency with modern C++
  • Practical experience with C++ development for data processing pipelines, including performance optimization and debugging
  • Hands-on Python skills and experience with building and maintaining data processing scripts and utilities
  • Hands-on experience with designing, implementing, and maintaining data pipelines in AWS environments
  • Upper-Intermediate English level or higher
  • Analytical and solution-oriented mindset with strong problem-solving and troubleshooting skills in complex data environments
  • Practical experience with data formats and serialization, including HDF5/Iceberg, and migrating or transforming data between formats (nice-to-have)
  • Experience with big data frameworks or ecosystems (as an advantage)
