Senior Java Developer (Trading Platform)

The Trading Infrastructure team is engaged in developing a state-of-the-art Trading Platform catering to multi-asset trading requirements. This platform prioritizes low-latency execution, robust risk controls, and seamless integration within trading, risk, operations, and finance workflows.

The system features a modular architecture incorporating key components such as market data feeds, order gateways, execution algorithms, risk engines, UI dashboards, middle office reconciliation, and account infrastructure. The team focuses on event-driven, deterministic system design, real-time observability, and robust security measures.

The technology stack comprises Java (low-latency), Python, Web UI (React/Ag-Grid), Aeron, ClickHouse, Kubernetes, and up-to-date CI/CD tooling, with a strong emphasis on automation, scalability, and performance. AI-driven development tools are also utilized to enhance productivity and code quality within the team.

Responsibilities

• Design and implement core backend systems including market connectivity, order routing, execution engine, risk management, and position tracking.
• Develop ultra-low-latency and garbage collection (GC)-free components employing best practices in lock-free and off-heap programming.
• Apply event-driven and fully deterministic design principles to ensure traceable and predictable system behavior.
• Collaborate closely with product and trading teams to transform requirements into efficient and production-ready solutions.
• Participate in performance profiling, JVM tuning, and troubleshooting complex production issues.
• Create and maintain automated test suites and CI/CD pipelines.
• Engage in code reviews, architectural discussions, and technical audits to uphold high standards within the codebase.
• Utilize AI-powered coding tools where suitable to expedite development and enhance productivity.

Requirements

• Minimum of 8 years of Java backend development experience, preferably within a trading or real-time system environment.
• In-depth understanding of Java core internals, multithreading, memory models, and garbage collection mechanisms.
• Demonstrated experience in GC-free or low-GC programming, leveraging tools like direct buffers and memory-mapped files.
• Knowledge of Aeron, SBE, or other low-latency messaging libraries.
• Proficient in event-driven architecture and skilled in designing fully deterministic systems.
• Familiarity with time-series and analytical databases such as ClickHouse; exposure to kdb+ or InfluxDB is advantageous.
• Experience with distributed systems, message queues, and performance optimization at the network and application layers.
• Proficient in utilizing AI-powered development tools to enhance code quality and development speed.
• Strong testing discipline including TDD, benchmarking, and resilience testing.

Communication and Collaboration

• Proficiency in English (spoken and written); knowledge of Chinese or other languages is beneficial but not mandatory.
• Comfortable collaborating with a global team spanning APAC, EMEA, and North America.
• Strong communication skills to engage effectively with stakeholders at all levels.
