The Role

As a Senior Engineer within the AHL OMS team you’ll be building the Order Management System underpinning the systematic investment process for AHL. 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 development of new investment strategies.

We are a small, close-nit team within our Markets Platform Engineering group, with the OMS sitting between AHL strategies and our 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. It’s a particularly exciting time to join as we’re currently investing heavily, evaluating our stack to increase both its performance and agility in onboarding new flows to support AHL’s future growth.

Our Technology

Our systems run on Linux via containers, with most systems built using Java. We use Git for source control, Jenkins for continuous integration, Grafana + Prometheus for metrics collection, Docker for containerisation, Ansible for architecture automation, and Slack for internal communication. We have access to all major frontier LLM models and harnesses, leveraging bespoke skills to both develop and support our systems. That said, our technology is never static: we constantly evaluate new tools and libraries.
