About The Position

As a Senior Java Engineer in Man Numeric’s OMT team, you will build and maintain the Order Management System that supports Numeric’s systematic investment process. You will work closely with the trading desk, quantitative strategy teams, and operations to deliver a flexible, robust, and performant system that safely processes millions of orders annually and supports onboarding new investment strategies.

Systems run on Linux in containers. The platform includes a Tomcat web application and microservices using Micronaut, alongside Python services, and uses event sourcing to propagate state events across service domains. Technologies and tools include Java, Python, Git, Jenkins, IntelliJ, GitHub Copilot, Grafana, Prometheus, Docker, Slack, Confluence, and Jira. The team continually evaluates new tools and libraries.
