Reference data is the foundation of every trading decision we make. From financial instruments and corporate actions to market calendars, counterparty data, and alternative datasets, the breadth and complexity of reference data continues to grow alongside the increasing sophistication and interconnected nature of global markets. We are looking for a Data Software Engineer to join our Global Data Engineering team to expand the coverage, quality, and robustness of our reference data products, which power low, medium, and high frequency trading strategies across the firm.
What you'll do:
- Establish vision and technical direction for major initiatives across our reference data platform
- Expand and harden existing reference data products — improving coverage across asset classes and datasets, raising data quality, and increasing operational robustness
- Design, develop, support, and maintain critical components of our data infrastructure that traders and researchers rely on every day
- Ensure new and existing programs adhere to our coding, architectural, and operational standards
- Develop a deep understanding of trading, exchanges, and the diverse data domains that underpin them
- Collaborate deeply with traders, engineers, and researchers to identify gaps, prioritise improvements, and deliver datasets that meet the bar of a top-tier trading firm
What you'll need:
- Strong engineering instincts and a deep understanding of computer science fundamentals
- Experience writing software in C++, C, C# and/or Python
- A pragmatic approach to data modelling — able to balance correctness, completeness, and the realities of messy upstream sources
- Innovative, big-picture thinking grounded in real-world pragmatism
- Desire to continuously improve in a rapidly evolving environment
- Readiness to set technical direction, promote engineering principles, and do the right things
