Job Overview:
We are currently looking for a talented Backend Developer to join our growing team.
Key Responsibilities: * Development of new HTTP and WebSocket endpoints with integration of third-party APIs (REST/gRPC/GraphQL — depending on tasks). * Writing unit and integration tests to ensure correct operation of APIs, including boundary cases and work with external services. * Performing load testing and code profiling to identify bottlenecks and improve performance. * Working closely with frontend, analytics and product teams — from discussing specifications to implementing solutions in production.
Requirements:
Must have: * Strong knowledge of Node.js and TypeScript, experience in REST/WebSocket API development. * Experience with microservice architecture and interaction between services via RabbitMQ, Redis, TCP connections. * Knowledge of PostgreSQL (query writing, indexing, transactions, migrations). * Experience with MongoDB and understanding when it is appropriate to use it. * Experience with Docker, understanding of how docker-compose works. * Understanding of the principles of Nginx as a proxy server (including in the context of WebSocket/HTTPS). * Proficiency with Socket.io, understanding of its features (e.g., rooms, reconnect, persistence, etc.). * Experience in configuring logging, debugging and profiling backend code.
Will be a plus: * Experience with Elasticsearch: setting up and using it for full-text search. * Load testing skills and tools (e.g. k6, Artillery, autocannon). * Understanding and implementation of HTTPS, certificates, working via secure WebSocket. * Experience with CI/CD and build automation in a Docker environment. * Team development experience: code review, git flow, Jira/YouTrack/Linear.
Goals for the probationary period: * Familiarize with the product architecture, internal processes and the stack used. * Integrate the first HTTP/WebSocket endpoints into the backend by connecting third-party APIs. * Participate in ongoing tasks to fix bugs and improve stability. * Gradually take responsibility for small modules and confidently navigate the codebase.
What we offer: * A dynamic work environment with a passionate team focused on sports and technology. * Paid sick leave (6 days) and 24 days of flexible vacation. * Opportunities for professional growth and career development. * Full remote work options and flexible working hours.
