Senior NodeJS Developer

About the Role We are looking for a Senior Node.js Developer to join our team and help build a distributed, high-load real-time networking platform that processes, transforms, and routes large volumes of HTTP and WebSocket traffic between clients and external services. This is a highly technical engineering role focused on network services, protocol-level development, observability, runtime integrations, and modern software architecture. Our platform is built as a large TypeScript monorepository running simultaneously on both Node.js and Bun, with a unified abstraction layer. We actively embrace AI-assisted development practices and expect engineers to take ownership throughout the entire software lifecycle—from research and design to implementation, testing, deployment, and continuous improvement. What You'll Do Core Platform Development Design, develop, and optimize services within our networking core. Build highly reliable systems for request processing, routing, load balancing, failover, and streaming data delivery. Contribute to platform scalability, performance, and operational excellence. Network Protocol Engineering Work directly with: HTTP/1.1 HTTP/2 WebSocket TLS CONNECT tunneling Compression technologies (gzip, brotli, zstd, deflate) Diagnose and resolve complex networking issues in production environments. Observability & Reliability Implement tracing, metrics, and logging using OpenTelemetry. Build dashboards and alerts generated directly from code. Analyze system behavior under load and improve operational visibility. Third-Party Integrations Maintain and extend runtime integrations with external web applications. Develop compatibility layers between internal systems and third-party clients. Software Engineering Excellence Write portable TypeScript code compatible with both Node.js and Bun runtimes. Ensure proper tree-shaking, modular design, and absence of cyclic dependencies. Participate in architecture discussions and technical decision-making. Full Ownership Delivery Own projects end-to-end: Research Design Planning Development QA Documentation Retrospectives Leverage AI tools as an integral part of the engineering workflow.
