  • Cloud & DevOps: Build and operate services on containerized Kubernetes infrastructure and contribute to CI/CD and IaC practices.
  • Code Quality & Mentorship: Conduct code reviews, write maintainable tested code, and mentor junior and mid-level engineers.

  • Experience with Kubernetes, Docker, and CI/CD pipelines.
  • Familiarity with cloud platforms such as AWS, Azure, or GCP.
  • Experience analyzing and modernizing legacy systems.
  • Proficiency using AI-assisted development tools such as Claude Code, Copilot, or Cursor.
  • Strong communication and technical collaboration skills.
