## About the Role

* 10+ years' commercial C++ development in complex or performance-critical systems.
 * Strong understanding of algorithms, data structures, concurrency and memory management.
 * Background in embedded systems, real-time control, or high-reliability software is perfectly suitable.
 * Ability to write clean, robust, well-tested code.
 * Comfortable working in a disciplined engineering environment with long-term product stability.

Desirable Experience

 * Exposure to Rust for systems programming or performance-critical modules.
 * Experience with messaging systems, market-data feeds, or distributed systems.
 * Familiarity with Linux development, networking, or hardware-adjacent engineering.

## Description

You'll work on high-performance, real-time trading software that processes market data, drives execution logic, and supports mission-critical investment workflows. Expect deep technical challenges across concurrency, optimisation, messaging, and deterministic system behaviour.

The environment suits engineers who enjoy precision, reliability, and long-term craftsmanship in C++.

Key Responsibilities

 * Design, develop and optimise C++ components for real-time trading and market-data systems.
 * Work on low-latency messaging, event-driven architectures and high-throughput data pipelines.
 * Collaborate with senior engineers to understand system behaviour, performance constraints and trading workflows.
 * Contribute to architectural discussions, code reviews and long-term platform evolution.
 * After the training period, take ownership of core modules within the trading stack.
