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. You’ll have direct exposure to a wide set of asset classes covering both listed and OTC markets, building deep understanding in how they’re executed and booked.

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.
