Senior C++ / Rust Engineer - Low Latency eTrading

JUXT·Senior·On-site · London, England, United Kingdom

Posted Oct 6, 2026·griddynamics.com

The Opportunity

JUXT is partnering with a Tier 1 investment bank on a major Fixed Income eTrading platform, where new systems are being built from the ground up in Rust.

The Platform Covers Two Core Electronic Trading Workflows

Pricing & Distribution – RFQ platform and electronic quoting
Hedging & Algo – automated hedging and algorithmic trading

The programme is modernising a legacy C++ application and replacing it with a modern, low-latency Rust platform.

We are looking for a Senior C++ Engineer with genuine low-latency electronic trading experience to help design and build this next-generation platform.

The Role

This is a hands-on engineering position focused on building high-performance, low-latency trading infrastructure.

You will bring strong C++ and electronic trading expertise while working with Rust to develop new capabilities across pricing, RFQ, quoting, hedging and algorithmic trading.

The role requires a deep understanding of what makes systems fast and predictable. You will be expected to apply principles such as mechanical sympathy, efficient memory layout, concurrency, lock-free techniques and disciplined performance measurement.

Responsibilities

Design and build new low-latency eTrading systems in Rust.
Apply established C++ low-latency engineering principles to a modern Rust platform.
Develop functionality across:
- RFQ and pricing
- Electronic quoting
- Hedging
- Algorithmic trading
Design systems for predictable and consistent latency.
Profile and measure system performance to identify optimisation opportunities.
Apply low-level performance techniques around memory, concurrency and CPU efficiency.
Develop reusable components that can be shared across the wider trading platform.
Work closely with the bank's eTrading engineers, architects and trading stakeholders.
Take ownership of technical problems from initial design through to production.
Help replace and modernise functionality within the existing legacy C++ trading platform.

Requirements

C++

Strong commercial C++ engineering experience.
Extensive experience building low-latency systems.
Strong understanding of modern C++ and performance-focused development.
Experience working with complex, production-grade systems.

Electronic Trading

Proven experience developing electronic trading systems.
