  • Familiarity with Docker, CI/CD pipelines, and Kubernetes
  • Strong communication and collaboration skills
  • Comfortable writing well-structured, maintainable code
  • Professional experience building or integrating AI-powered systems in production, including work with LLM APIs (e.g. OpenAI, Claude), prompt engineering, or agent frameworks.
  • Experience building internal tools or customer-facing AI features
