Phi Partners is a global Capital Markets IT consultancy, providing technology expertise to Tier-1 investment banks, hedge funds and asset managers. Founded in 2004 and headquartered in London, Phi operates branches across North America, EMEA and APAC. Phi specialises in Front Office and Risk Technologies, and our niche focus on these domains has been a differentiator and gateway into the world’s most renowned financial institutions. We work exclusively in capital markets, which allows us to provide a depth of expertise that generalist consultancies cannot match. Our consultants partner directly with front office trading desks, quantitative research teams, and technology stakeholders to deliver projects that are both technically challenging and commercially critical. We are rapidly expanding out centres of excellence in Europe and the Americas, with senior engineers leading buildouts for both buy side and sell side clients.

About the Programme

The client is running a strategic multi-year initiative across its Fixed Income IT organisation to modernise core trading platforms.

Key priorities include improving data integration and distribution pipelines, strengthening system resilience, and enhancing execution workflows for products such as interest rate swaps, US treasuries, futures, and other fixed income asset classes.

This transformation effort is highly visible, with quants and traders relying directly on these systems for pricing models, trade execution, and market connectivity. You will be hands-on in the design, coding, and optimisation of low-latency applications, collaborating closely with Front Office desks, quants, compliance, and IT teams.

• Design, develop, and enhance front office pricing engine/eTrading systems
• Enhancing legacy codebases while also driving modernization/microservices transformations
• Develop and maintain system architectures, designs, and concepts
• Interface directly with trading desks, quantitative analysts, and risk/compliance teams
• Maintain and improve code quality via static/dynamic analysis, CI/CD pipelines, and security vulnerability scans
• Deliver across the full SDLC from analysis through to production support

• Strong Java (JDK 11/17) & Spring expertise, with experience in low-latency, high-throughput trading systems
• Knowledge of fixed income instruments (IRS, CDS, bonds, treasuries, futures)
• Skilled in REST APIs, JMS (ActiveMQ), SQL (MS SQL/Sybase)
• Proficient in multithreading, concurrency, asynchronous/event-driven programming
• Strong communicator with FO user engagement (Traders, Quants, Risk, Compliance)
