Have experience leveraging AI coding assistants like Cursor, Claude Code, and other LLM powered tools while maintaining high standards for code quality, architecture, and maintainability

Have experience with data integrations and working with complex data flows

Can work directly with clients, translating business needs into technical solutions and communicating clearly

Embody high agency: you identify problems, propose solutions, and follow through independently

Bonus: experience training or fine-tuning ML models, familiarity with multiple cloud platforms, or data engineering background
