Role Overview
A collaborative and entrepreneurial systematic investment team is seeking an experienced Quantitative Trading Systems Engineer to join its Systematic Macro trading team.

Working closely with the Senior Portfolio Manager, you will build and maintain the pod’s low-latency trading infrastructure across Futures, FX, and Fixed Income.
The successful candidate will join the systematic macro pod to build the real-time, performance-critical C++ infrastructure that runs the team’s trading — from the production alpha infrastructure through to execution. The role also focuses on production integration, deployment, monitoring, and live trading support, and on liaising with central technology teams to leverage the firm’s existing data and execution services.
Principal Responsibilities
- Build the team’s C++ latency-sensitive trading systems from market data ingestion to order execution
- Productionise performance-critical signal computation within the trading systems
- Build the supporting research infrastructure, including replay and data management
- Support execution-related workflows across systematic strategies in Futures, FX, and Fixed Income
- Specify the team’s performance and infrastructure requirements to central technology teams and work with them to deliver
- Partner with broader technology teams to make effective use of the firm’s shared platforms and services — execution, risk, portfolio management, data, and monitoring
- Implement and maintain team-level trading controls and support live production processes, while ensuring appropriate integration with the firm’s broader trading control framework
