Senior Java Developer (Trading Platform), Canada

The Trading Infrastructure team is focused on constructing a cutting-edge Trading Platform to facilitate multi-asset trading efficiently. The platform aims to support a wide range of financial instruments with a strong emphasis on low-latency execution, robust risk controls, and seamless integration across various workflows including trading, risk, operations, and finance.

The system architecture follows a modular approach encompassing key components such as market data feeds, order gateways, execution algorithms, risk engines, UI dashboards, middle office reconciliation, and account infrastructure. Design principles center around event-driven, deterministic system design, real-time observability, and stringent security protocols.

The technology stack utilized comprises Java (low-latency), Python, Web UI (React/Ag-Grid), Aeron, ClickHouse, Kubernetes, and modern CI/CD tools. Automation, scalability, and performance optimization are key focus areas, with AI-powered development tools playing a role in enhancing productivity and quality across the team.
