Job description

The Trading Infrastructure team is building a high-performance, front-to-back Trading Platform that supports multi-asset trading. The platform is designed to handle financial instruments with low-latency execution, robust risk controls, and seamless integration across trading, risk, operations, and finance workflows.

The system is built with a modular architecture encompassing core components such as market data feeds, order gateways, execution algorithms, risk engines, UI dashboards, middle office reconciliation, and account infrastructure. We emphasize event-driven, deterministic system design, real-time observability, and strong security.

Our tech stack includes Java (low-latency), Python, Web UI (React/Ag-Grid), Aeron, ClickHouse, Kubernetes, and modern CI/CD tooling, with a strong focus on automation, scalability, and performance. AI-assisted development tools are also leveraged to boost productivity and quality across the team.

Responsibilities

• Design, develop, and maintain high-performance WebUIs for trading functions such as order tickets, real-time blotters, position views, and time series charting.
• Build advanced UI components using React.js, Next.js, and Ag-Grid, focusing on modularity, performance, and responsiveness.
• Translate complex trading workflows (including options and multi-leg strategies) into intuitive, trader-friendly interfaces.
• Integrate frontend with real-time backend systems such as AMPS, ViewServer, and custom messaging protocols.
• Implement and contribute to microfrontend and microservices architectures in a scalable multi-team environment.
• Collaborate with backend teams working in Java, Python, and scripting tools to develop and support fullstack features.
• Use AI-assisted coding tools (e.g., GitHub Copilot, CodeWhisperer) to boost development efficiency while maintaining high code quality.
• Participate in architectural reviews, code audits, and performance profiling to ensure a robust and maintainable codebase.

Requirements

• Minimum 5+ years of experience in frontend or fullstack development, preferably within trading or financial systems.
• Deep expertise in React.js, Next.js, and Ag-Grid, plus strong familiarity with modern state management libraries (Redux, MobX, XState, etc.).
• Solid experience building UI for trading systems including blotters, risk dashboards, and charting tools.
• Proven ability to integrate frontend with real-time streaming backends (e.g., AMPS, ViewServer) and WebSocket/REST APIs.
• Strong understanding of the order lifecycle, market data, and trading of instruments such as spot, futures, and options.
• Experience with backend development using Java is required — including API integration, business logic, and collaboration with platform teams.
• Familiarity with microfrontend architecture and UI composition techniques.
• Comfort with modern frontend tooling, code profiling, testing, and performance optimization.
• Able to use AI-powered development tools to streamline coding and maintain quality.

Communication & Collaboration

• Proficient in English (spoken and written); Chinese or other languages are a plus but not required.
• Comfortable working in a global team with colleagues across APAC, EMEA, and North America.
• Strong communication skills; able to interface across all levels from senior leadership to developers and cross-functional stakeholders.
• Able to explain complex workflows to both technical and non-technical audiences and drive alignment across teams with diverse backgrounds.
