• Acting as the interface between Front Office users and Data Engineering
• Translating complex, ambiguous business needs into structured technical specifications and data models
• Supporting onboarding of market and alternative datasets, including vendor integration challenges
• Driving data quality, reconciliation, and validation processes across multiple data sources
• Contributing to data modelling, schema design, and transformation logic
• Operating within a modern architecture including Data Mesh principles, data contracts, and governance frameworks
• Supporting large-scale initiatives including historical backfills, PoCs, and new data product delivery
• This is a greenfield-to-scale data platform build, with direct exposure to Data Engineering leadership and global stakeholders. What they're looking for
• +10 years' experience in financial services (buy-side or trading environments preferred)
• Strong expertise in SQL and data modelling (schemas, normalization, performance optimisation)
• Deep experience working with market data across asset classes, including vendor integration and financial identifier mapping (ISIN, CUSIP, etc.)
• Strong understanding of data pipelines, data quality/reconciliation, and OLTP vs OLAP paradigms
• Technical background, with hands-on programming experience (Python, Java or similar) and prior experience in engineering or development roles
• Proven track record operating as a hybrid between engineering and business, shaping data products and requirements
• Experience working closely with Data Engineering teams on scalable data platforms (not just reporting environments)
• Strong stakeholder engagement skills, with daily interaction with Front Office users (PMs, trading teams)
