Join us as a **Principal Engineer – Trading Core** and take technical ownership of the heart of Pepperstone's trading platform. Our Java-based trading engine powers order management, pricing, market data, risk management and client APIs—processing real client orders and funds in real time. You'll define the technical direction for a mission-critical, regulated platform, driving its evolution towards a more scalable and resilient architecture while keeping a live trading system running 24/7. As a senior individual contributor, you'll lead through architecture, design and code—not people management—setting engineering standards, solving complex technical challenges and helping shape the future of Pepperstone's trading platform.
