AI-assisted engineering – demonstrable hands-on use of Claude (including Claude Code), GitHub Copilot or comparable assistants to build enterprise-grade production software, including prompt and context engineering, AI-assisted refactoring, test generation and documentation. AI enablement – experience building reusable AI assets (prompt libraries, agents, workflow automations, MCP-based integrations) and helping engineering teams adopt them. AWS – 3+ years designing and deploying solutions using services such as EC2, ECS/EKS, Lambda, S3, RDS, API Gateway, IAM and CloudWatch, with infrastructure-as-code and cloud migration experience. Strong REST API design and system-to-system integration experience, and 4+ years in RDBMS/RDS such as SQL Server including data modelling and query tuning.

Good-to-Have Skills Enterprise generative AI platforms (Claude for Enterprise, ChatGPT Enterprise, custom GPTs) and building Model Context Protocol (MCP) integrations to enterprise systems. Supporting technology adoption through training, office hours or communities of practice, including measuring adoption and productivity impact. Responsible AI, data privacy, information security and access management; automated testing and regression frameworks for validated systems.
