The Team

We are a small team within our Markets Platform Engineering group, with the OMS sitting between Numeric strategies and the Man central execution systems which act as the interface to the market. We’re in the core position of the investment process and interact with many other parts of the firm, providing a unique opportunity to build comprehensive knowledge across the trading lifecycle.

Role Responsibilities

As an Senior Java Engineer within the Man Numeric OMT team, you’ll be building and maintaining the Order Management System underpinning the systematic investment process for Numeric. This is an opportunity to work closely with our trading desk, quant strategy teams, and operations to deliver an Order Management System that is flexible, robust, and performant to safely trade millions of orders annually and enable the onboarding of new investment strategies for our clients. You’ll have direct exposure to cash equities, equity swaps, and futures asset classes covering both listed and OTC markets, while building deep understanding in how they’re executed and booked.

This role offers a unique opportunity to learn soup-to-nuts how data is transformed from investment signals into trading decisions ensuring the trading life cycle is robust and scalable. This position requires support coverage and also offers advancement opportunities within Man Front Office Technology.

Our Technology

Our systems run on Linux via containers, with most systems built using Java and a bit of Python. The platform consists of a Tomcat web application along with a suite of microservices running on the Micronaut framework and others on Python. The platform utilizes event sourcing architecture to propagate state events across service domains. We use Git for source control, Jenkins for continuous integration, Jetbrains IntelliJ IDE with GitHub Copilot license, Grafana + Prometheus for metrics collection, Docker for containerisation, Slack for internal communication, and much of the Confluence stack including Jira to run our Scrum sprints. That said, our technology is never static: we constantly evaluate new tools and libraries.
