Important to be able to: - Work with Claude Code / Codex / Cursor / GitHub Copilot or similar tools. - Decompose large tasks for AI agents. - Provide agents with context, rules / skills / instructions. - Use AI for development, testing, Code Review, documentation, refactoring and legacy analysis. - Organize work of multiple agents with different roles. - Verify and accept generated code, not blindly rely on AI results. - Understand LLM limitations: hallucinations, context loss, overcomplication, architecture errors and potential security issues. - Maintain personal responsibility for the technical result regardless of how much work was done by AI. What is important for us: - Commercial development experience from 5 years. - Strong knowledge: TypeScript + Node.js + React + PostgreSQL. - Practical experience in designing entire systems, not just frontend architecture. - Understanding of System Design: monolithic and microservice architecture, API, DB, queues, caching, integrations. - Ability to work with non-functional requirements: performance, load, scalability, fault tolerance, security and observability. - Experience with Docker and CI/CD. Knowledge of Kubernetes is a plus. - Experience with Code Review, Unit and Integration Testing. - Ability to independently decompose a task and estimate development in hours. - Experience launching solutions from requirements to production. - We especially value independence: if given a business task, we expect you to understand requirements, ask necessary questions, propose architecture, assess risks and effort, organize development and bring the result to production. Will be a plus: - Redis - Kafka / RabbitMQ - MongoDB - Kubernetes - Prometheus / Grafana / Sentry - Experience with high-load systems - Complex integrations with external systems - Participation in presale and technical evaluation of new projects - Experience in technical leadership or mentoring developers
