• Collaborate with clients to refine matching logic and improve results over time
• Create documentation and guidelines that help clients understand how their AI matching works
• Monitor Lakefusion for matching performance and troubleshoot issues when results aren't meeting expectations
• Share best practices and learnings across client implementations

• 1+ years working with LLMs and prompt engineering in production or client-facing roles
• Strong client communication skills - you can explain technical concepts clearly and understand business requirements
• Experience designing prompts for data matching, classification, or extraction tasks
• Understanding of different LLM options (GPT-4, Claude, open source models) and their tradeoffs
• Knowledge of entity resolution, data matching, or MDM concepts
