About Phi Partners 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 Client Engagement Our client is a Tier-1 global bank with nearly 60,000 employees worldwide and an AUM of $2.1 trillion, with a strong presence across fixed income and derivatives markets. Recognised for their investment in technology, they are undertaking a multi-year programme to modernise and strengthen their Front Office eTrading platforms supporting trading, risk, and regulatory functions. These platforms are critical for low-latency pricing, accurate valuations, competitive execution, and regulatory compliance. Consultants will work directly with Front Office users (traders, quants, risk and compliance teams) to deliver scalable, high-performance systems with tangible business impact. About the Programme The client is running a strategic multi-year initiative across its Fixed Income IT organisation to modernise core trading platforms. The programme covers Front Office pricing engines, maintaining and enhancing legacy components while transitioning to modern, microservices based architectures. 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.
