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 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.
