Senior Java Developer; Trading Platform

Overview

The Trading Infrastructure team is building a high-performance, front-to-back Trading Platform that supports multi-asset trading. The platform handles financial instruments with low-latency execution, robust risk controls, and seamless integration across trading, risk, operations, and finance workflows. The system is modular, including core components such as market data feeds, order gateways, execution algorithms, risk engines, UI dashboards, middle office reconciliation, and account infrastructure.

We emphasize event-driven, deterministic design, real-time observability, and strong security. Our tech stack includes Java (low-latency), Python, Web UI (React/Ag-Grid), Aeron, Click House, Kubernetes, and modern CI/CD tooling, with a focus on automation, scalability, and performance. AI-assisted development tools are leveraged to boost productivity and quality across the team.
