Low Latency eTrading Engineer - C++ & Rust (Hybrid in NYC)

About the Role

We are partnering with a Tier 1 investment bank on its Fixed Income eTrading platform, where next-generation systems are being written from the ground up in Rust. As a technology solutions provider, our engineering teams are delivering modern, high-performance infrastructure across both pricing/distribution and hedging/algorithmic trading.

In this role, you will be embedded alongside our client's core eTrading engineers to build critical components at the heart of the new platform. You will apply hard-won low-latency C++ engineering principles to design, benchmark, and deploy low-latency eTrading systems in Rust, taking ownership of core delivery while examining and transitioning capabilities from existing C++ codebases.

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

Ideal Candidate Profile

This role is ideal for a low-latency specialist who wants to build trading infrastructure properly from line one. The ground-up Rust mandate offers a rare opportunity to apply deep C++ performance instincts in a modern language free from legacy constraints. You will excel here if you thrive in a senior, engineering-focused team working close to the trading business.
