KDB Developer - Macquarie Group

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.

As a KDB Developer, you will play a key role in running, enhancing and modernising our KDB ecosystem, partnering closely with quants, traders and business users to support our Quantitative Investment Strategies business. You will join a small, hands‑on team where contribution is visible and ownership grows quickly, with genuine end‑to‑end exposure across the full data lifecycle, from onboarding real‑time and historical market data through to building analytics engines and historical databases that support research and backtesting, while ensuring the platform operates reliably in a live production environment. You will be involved in the modernisation of our KDB ecosystem, refining existing components and developing new features, reducing operational overhead through automation, and supporting our ongoing cloud migration. As the platform continues to evolve, the team is also focused on exploring and applying AI‑driven capabilities.

Key responsibilities:

• Design, develop and maintain KDB+/q applications, including real‑time data ingestion, analytics engines and historical databases
• Build and optimise data pipelines and large‑scale time‑series data structures
• Collaborate with quants, traders and business users to deliver data, tools and analytics supporting trading, risk and research requirements
• Onboard and integrate real‑time and historical market data sources
• Implement data quality checks, monitoring frameworks and system observability across KDB environments
• Work closely with DevOps/SRE teams to support reliable deployment, capacity planning and performance tuning
• Troubleshoot data issues, performance bottlenecks and production incidents, contributing to ongoing platform support
• Contribute to the design and evolution of scalable data solutions
• Support platform modernisation initiatives, including automation, cloud migration and AI‑enabled capability

What you offer:

• Hands‑on experience with KDB+/q, ideally within a production or data‑driven environment, with a good understanding of the data lifecycle
• Ability to write efficient q queries, with an appreciation for performance, scalability and memory optimisation
• Experience working with market or time‑series data, ideally with exposure to real‑time data feeds (e.g. Bloomberg, LSEG/Refinitiv)
• Solid knowledge of Linux/Unix environments, with experience in scripting and working within distributed systems
