About the role:

At Cresta, the Insights Team is dedicated to leveraging Large Language Models (LLMs) and AI techniques to extract actionable intelligence from conversations. We develop models and systems that analyze customer interactions, identify key topics, and provide structured insights that impact business outcomes. Our work enables organizations to make data-driven decisions and optimize customer experience through AI-powered exploration and interactive workflows.

A key focus of this role is developing agentic workflows that empower users to dynamically interact with AI-driven insights, refining and guiding the discovery process in an interactive and iterative manner. Additionally, this role will involve designing and implementing LLM evaluation frameworks to assess model performance, reliability, and usability in real-world applications. Our goal is to provide users with intelligent, context-aware AI agents that surface the most relevant insights and allow for deeper exploration of conversational data.

As a Machine Learning Engineer, you will be at the forefront of applying state-of-the-art NLP and LLM techniques to understand conversations at scale. Your work will focus on developing robust, scalable AI solutions that extract meaning, evaluate LLM effectiveness, and provide real-time insights to our customers through intuitive, agent-driven workflows.
