As a Java Engineer you will be building the tools, platforms and algorithms that enable Man’s investment engines – AHL, Numeric and our Discretionary teams – to drive forward their centralized global trading operation. Your challenges will be varied and might involve building new execution algorithms, the platforms on which they run, simulation environments, intelligent order routing, connectivity to execution venues and brokers, tools for high touch and quant traders, monitoring capability, post-trade performance analysis and software to optimize all aspects of the trading lifecycle.

We are continually expanding the markets, asset classes and regions in which we trade as well as the styles in which we trade them. The team is responsible for designing imaginative and flexible software and tools to keep pace with this change.

We are looking to hire talented software engineers across the experience spectrum, and previous experience with almost any asset class will be an advantage.

The team is currently undergoing significant investment to rationalize the trading capability across AHL, Numeric and the Discretionary teams. The engineering team works exceptionally closely with both the Trading Desk and the Execution Research team to design, build and maintain a world-class trading capability. We have trading floors in London, Hong Kong, Boston and New York and are responsible for trading more than 8 trillion dollars annually.

Our systems are almost all running on Linux and most of our code is in Java, with some Python and Type Script.

We use Kafka as the backbone of our platform, Aeron, Git for source control, Jenkins for continuous integration, Grafana Prometheus for metrics collection, Docker for containerization, Ansible for architecture automation, and Slack for internal communication.
