Senior Java Developer (Trading Platform)

The Trading Infrastructure team is tasked with constructing a high-performance Trading Platform that supports multi-asset trading from end to end. This platform is specifically engineered to handle financial instruments with low-latency execution, robust risk controls, and seamless integration across key trading, risk, operations, and finance workflows.

The system is fashioned with a modular architecture consisting of core components like market data feeds, order gateways, execution algorithms, risk engines, UI dashboards, middle office reconciliation, and account infrastructure. The emphasis is on an event-driven, deterministic system design approach, real-time observability, and stringent security measures.

Utilizing a tech stack that comprises Java (optimized for low-latency), Python, Web UI (React/Ag-Grid), Aeron, ClickHouse, Kubernetes, and modern CI/CD tools, the team follows a strong focus on automation, scalability, and performance. Additionally, AI-assisted development tools are leveraged to enhance productivity and quality for the team.

Responsibilities

• Design and develop core backend systems involving market connectivity, order routing, execution engine, risk management, and position tracking.
• Implement ultra-low-latency and GC-free components using recommended 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 translate requirements into high-performing, production-ready solutions.
• Engage in performance profiling, JVM tuning, and troubleshooting complex issues in production.
• Create and maintain automated test suites and CI/CD pipelines.
• Participate in code reviews, architectural discussions, and technical audits to ensure elevated standards across the codebase.
• Leverage AI-driven coding tools (e.g., GitHub Copilot) for faster development and improved productivity, where applicable.

Requirements

• Possess at least 8 years of Java backend development experience, preferably in a trading or real-time system environment.
• In-depth understanding of Java core internals, multithreading, memory models, and garbage collection.
• Demonstrated experience in GC-free or low-GC programming, including working with related tools like direct buffers and memory-mapped files.
• Familiarity with Aeron, SBE, or other low-latency messaging libraries.
• Strong grasp of event-driven architecture and proven experience in designing fully deterministic systems.
• Sound knowledge of time-series and analytical databases like ClickHouse, with exposure to kdb+ or InfluxDB considered a plus.
• Experience with distributed systems, message queues, and proficiency in performance tuning at network and application levels.
• Comfortable in using AI-powered development tools to enhance code quality and development speed.
• Strong testing discipline encompassing TDD, benchmarking, and resilience testing practices.

Communication and Collaboration

• Proficient in English (spoken and written); knowledge of Chinese or other languages is beneficial but not mandatory.
• Ability to work effectively in a global team with colleagues spanning APAC, EMEA, and North America.
• Strong communication skills enabling effective interaction across all levels, from senior leadership to engineers and stakeholders.
