• Experience working with large datasets and data processing technologies such as Apache Spark.
• Strong understanding of software testing, CI/CD, application security and operational resilience.
• Practical experience with cloud-native technologies, containers and Kubernetes.
• Experience working within Agile development environments.
• Understanding of secure software development practices and responsible AI principles.

Nice to Have

• Experience with AWS cloud services.
• Hands-on experience with Databricks and MLOps frameworks.
• Knowledge of Model Context Protocol (MCP) and AI agent orchestration.
• Experience with AI evaluation frameworks, LLM-as-a-judge techniques and automated regression testing.
• Familiarity with OpenTelemetry, observability and distributed tracing.
• Experience developing AI-powered copilots or enterprise GenAI applications.
