Java Engineer – Fixed Income eTrading Platform (Hybrid in NYC)

About the Role

We are partnering with a Tier 1 investment bank to build its next-generation Fixed Income and Rates eTrading platform—a greenfield initiative delivering a cutting-edge trading system at global scale. As a technology solutions provider, our engineering teams build high-impact client systems designed for scalability, integration, and operational excellence.

Around the platform’s low-latency core sits a family of general-purpose applications and services that make the platform operable, connected, and scalable across a global trading business. In this role, you will build these critical Java services, integrating across Solace and Kafka messaging systems while collaborating closely with the platform's core low-latency and front-end engineering teams.

Location: New York City, NY (hybrid - 3 days/week office attendance)

Ideal Candidate Profile

This position is ideal for an engineer who thrives on greenfield work with genuine impact—building a global trading platform from scratch without the constraints of legacy code. While these services sit outside the ultra-low-latency core, they are vital to the platform's overall success, making this role a perfect fit for a practitioner who takes pride in software craft and building things right from day one.
