KDB+ Developer

Our Data Services KDB team plays a key role in developing the platforms that underpin our Commodities and Global Markets business, partnering closely with our Quantitative Investment Strategies (QIS) teams.

Sitting at the centre of how data is used across trading, risk hedging and quantitative research, the team supports a platform spanning both real-time and historical data workflows. We ingest and process market data used in live trading environments, while maintaining large-scale historical datasets that enable quant teams to research and backtest strategies before they move into production. The platform operates across a broad, multi-asset landscape, with a strong and differentiated focus on commodities, alongside options, futures and index products.

We are a global financial services group operating in 30 markets with 57 years of unbroken profitability. At Macquarie, you’re empowered to shape a career that is fulfilling and creates value. You will bring your insights and expertise to the task at hand and feel supported as you make your own kind of impact for a better future.
