🛠 Tech Stack

💼 About This Role

You'll design and build high-performance backend systems for a multi-asset trading platform using low-latency Java. You'll implement GC-free components and deterministic event-driven architectures to ensure low-latency execution and robust risk controls. The role offers the chance to work with cutting-edge technologies like Aeron and ClickHouse in a hybrid Hong Kong team.

🎯 What You'll Do

• Design and develop core backend systems for market connectivity and order routing.
• Implement ultra-low-latency and GC-free components using lock-free and off-heap programming.
• Apply event-driven and deterministic design principles for traceable system behavior.
• Collaborate with product and trading teams to translate requirements into solutions.

📋 Requirements

• 8+ years of Java backend development in trading or real-time systems.
• Deep understanding of Java core internals, multithreading, and garbage collection.
• Proven experience in GC-free or low-GC programming with sun.misc.Unsafe and direct buffers.
• Familiarity with Aeron, SBE, or other low-latency messaging libraries.

✨ Nice to Have

• Experience with ClickHouse, kdb+, or InfluxDB.
• Experience with distributed systems and performance tuning.
• Proficiency in Chinese or other languages.
