  • Experience with testing frameworks (xUnit, WireMock or similar)
  • Strong skills in caching strategies (Redis / Valkey)
  • Experience with CI/CD pipelines (GitHub Actions, TeamCity)
  • Familiarity with Terraform (Infrastructure as Code)
  • Experience using GitHub (repos, workflows, collaboration practices)
  • Interest in modern development practices, including AI-assisted development tools (GitHub Copilot, ChatGPT)
  • Fluency in English


Nice to have:

  • Experience with AWS data services (Firehose, Data Streams, S3 integration patterns)
  • Exposure to LLM-based solutions or AI-assisted systems
  • Experience working in high-scale distributed environments
  • Knowledge of performance optimization and system reliability patterns


Our Values:

  • Engineering excellence and technical autonomy
  • Focus on scalable, production-grade solutions
