  • Experience with CI/CD, containerization (Docker), and cloud platforms (AWS/GCP)
  • Passion for performance, security, and clean architecture
  • A team player who’s also self-driven and proactive in solving problems

Nice to have

  • Knowledge of OpenAPI, OAuth2, or distributed systems
  • Contributions to open-source projects or internal developer tools
