Node Backend Engineer for Trading Platform Development

About the Role We are building a next-generation trading and investment platform and are looking for a talented Backend Engineer to help develop high-performance, scalable, and secure server-side systems across our ecosystem. This includes our order management system, market data aggregation layer, user portfolio services, and real-time notification infrastructure, with a strong focus on low-latency performance, data integrity, and robust system architecture. Key Responsibilities - Design, develop, and maintain high-performance backend services using Node.js (TypeScript/NestJS/Express). - Build and optimize core trading infrastructure including order routing, execution engines, position management, and real-time market data processing. - Collaborate closely with product, frontend, and QA teams to define APIs and deliver reliable, scalable features. - Design and maintain secure RESTful and WebSocket APIs for frontend consumption and third-party integrations. - Integrate with market data providers, brokerage APIs, and financial data feeds. - Ensure high availability, fault tolerance, and data consistency across distributed systems handling financial transactions. - Contribute to backend architecture, database schema design, caching strategies, and code quality standards. - Implement robust logging, monitoring, and alerting to ensure system health and rapid incident response. Technical Requirements - Strong experience with Node.js, TypeScript, and modern backend frameworks (NestJS, Express, or Fastify). - Experience building data-intensive, real-time systems (trading platforms, payment processing, or analytics pipelines). - Solid understanding of database technologies (PostgreSQL, MongoDB, or TimescaleDB) and query optimization. - Experience with message queues and streaming platforms (RabbitMQ, Kafka, or Redis Streams) for handling high-throughput data. - Strong understanding of API design (REST, WebSockets, gRPC) and API security (OAuth, JWT, API keys). - Experience with caching strategies (Redis, Memcached) for low-latency responses. - Familiarity with containerization and orchestration (Docker, Kubernetes) and cloud platforms (AWS, GCP, or Azure). - Strong focus on writing testable, maintainable code with comprehensive unit and integration tests. Project Scope - Initial focus on the order execution engine, market data aggregation layer, and core user portfolio services. - Expansion into full platform development, including risk management systems, reporting pipelines, and third-party integrations. - Opportunity for long-term collaboration based on performance. - Fully remote, flexible working hours. Who We're Looking For We are looking for someone who can go beyond implementation and contribute to building a fast, scalable, and resilient trading infrastructure for users in a complex financial data environment. If you thrive on performance challenges, care deeply about system reliability, and enjoy working with real-time financial data, we'd love to hear from you.
