This role focuses on the design, development, and optimization of backend services, APIs, and platform infrastructure that power modern web applications and collaborative systems. The ideal candidate will have deep expertise in building scalable backend architectures, integrating modern service technologies, and modernizing legacy platforms through modular microservices and API-driven designs. Engineers hired into this role will work within Agile Feature Teams responsible for specific areas of the platform. Each team focuses on a different product domain and technical architecture. Key Technologies: GoLang WebAssembly (WASM) APIs supporting React-based front-end applications Real-time collaboration services and platform performance optimization This position will work closely with product teams, UI engineers, DevOps, and QA teams to deliver secure, scalable, and high-performing backend services. Position Responsibilities In this role, you will: Design and develop scalable backend services and APIs using GoLang and modern service frameworks to support platform functionality and real-time system operations. Support backend services powering and core platform services across the ecosystem. Integrate and support WebAssembly (WASM) modules within backend architectures to enable high-performance processing and advanced application capabilities where applicable. Architect and maintain RESTful and GraphQL APIs supporting distributed applications and real-time collaboration features. Refactor and modernize legacy backend systems into modular microservices or service-oriented architectures. Develop backend infrastructure supporting real-time communication, event processing, and collaborative platform capabilities. Optimize system performance through efficient concurrency models, caching strategies, and scalable service design. Implement secure service communication, authentication, and data access patterns aligned with enterprise security standards. Collaborate closely with UI developers using React and TypeScript to ensure seamless integration between user-facing components and backend services.
