We’re seeking a proactive Trading Developer to architect and enhance the data and process backbone of our trading environment. You’ll design and implement backend APIs, real-time data pipelines, and monitoring frameworks—ensuring reliable, low-latency access to market and operational data. While your core focus is backend development, any front-end or full-stack experience will be a welcome bonus.

The trading developer will work closely with quantitative-analysts and trading management to develop a new trading product. The role will initially be the only developer within the Trading Department and is a great opportunity to work towards leading a growing team in the future.
