This is your chance to build the brain and nervous system of a global equities trading platform! What You’ll Do: Architect and build the foundational framework powering this new trading ecosystem. Design, code, and own components like: Smart Order Routers Matching Engines Real-Time Risk Engines Automated Trading Strategies Dive deep into Java, squeeze out latency, and think in nanoseconds.

Be on the frontlines of innovation — and back it up with production-level reliability. What You Bring: A creative engineering mindset and a passion for low-level, high-performance design. 10 years of hands-on Java wizardry, ideally within real-time trading environments. Mastery of concurrency, memory management, and low/no GC strategies. The confidence to build mission-critical systems and the curiosity to explore new ideas.

You’ll help define a new standard in electronic trading. You’ll work with people who respect speed, quality, and creative engineering. You’ll have ownership, autonomy, and greenfield glory. If you’re ready to engineer the future of trading, my client will want to hear from you!
