Market Data Java Engineer - Banking

Market Data Java Engineer - Refinitiv Migration About the role Join BIP UK as a full-time consultant supporting a client’s futures algorithmic trading platform. You’ll migrate the platform’s market data integration from the deprecated LSEG/Refinitiv Robust Foundation API (RFA) to the Real-Time SDK (RTSDK), preserving trading behaviour, performance and reliability through a phased rollout.

You’ll work hands-on in an existing Java codebase, tracing how the platform consumes futures and options market data, mapping exchange fields and behaviour to RTSDK, and making the application and shared library changes needed for production.

Compare RFA and RTSDK market data fields across supported futures and options exchanges.

• Document differences and assess their impact on trading workflows and downstream processing.
• Design and implement the RTSDK integration in the Java application and shared framework libraries. Assess performance, scalability and algorithmic efficiency across real-time data workflows.
• Plan and implement a phased rollout that maintains backward compatibility during the transition.
• Use test-driven development, automated tests and regression testing to verify that market data processing, volume counting and trading behaviour remain consistent after migration.
• Work with client developers, QA, trading and business stakeholders from analysis through rollout. Use AI-assisted development tools where appropriate for code analysis, implementation and testing. Essential skills and experience
• At least seven years of professional Java development experience, including hands-on work on production systems.
• Hands-on experience with LSEG/Refinitiv futures and options market data in electronic trading systems, and experience building or enhancing production trading applications.
• Strong understanding of exchange feeds, real-time market data processing and electronic trading workflows.
• Ability to navigate, troubleshoot and extend complex codebases and shared libraries, with attention to performance, scalability and reliability.
• Experience delivering phased API or platform migrations while maintaining backward compatibility.
• Hands-on experience with test-driven development, automated and regression testing, and Agile software delivery.
• Familiarity with AI-assisted development tools and agents for code analysis, development and testing.
• Strong analytical skills, the ability to work independently, and clear written and verbal communication with technical and business stakeholders. Desirable experience
• A previous RFA-to-RTSDK migration or a comparable market data platform modernisation.
• Low-latency trading systems and real-time market data processing.
• Designing shared frameworks or libraries, or developing shared trading platform components.
• Futures market structure, exchange connectivity, market data normalisation and exchange-specific feed behaviour. About BIP UK BIP is a global business and technology consultancy.
