In this role, you will leverage AI to automate reporting, workflows, and decision-making across the organization while solving complex technical and compliance challenges. You will receive hands-on guidance, mentorship, and feedback from the Senior Manager of AI Integration, while owning meaningful components of Crunch’s AI roadmap.

The scope of work is intentionally broad. You may contribute to everything from training and deploying machine learning models, to scaling AI infrastructure, to building and shipping predictive models and other workflows. As part of a growing AI function, you will also have the opportunity to help shape how the AI team, systems, and capabilities evolve over time.

Essential Functions / Major Responsibilities:

• Machine Learning & Predictive Modeling: Assist in the design, development, and refinement of machine learning models, with a specific focus on customer churn prediction and member lifetime value analysis. Utilize Python to process historical data and generate actionable insights for retention strategies.
• Quality Assurance & Optimization: Conduct continuous monitoring and testing of customer-facing voice and chat agents to ensure high-quality, empathetic, and accurate interactions. Analyze conversation logs to identify performance issues and implement logic or prompt adjustments to improve resolution rates.
• Prompt Engineering: Develop and iterate complex system prompts for Large Language Models (LLMs) to ensure consistent brand voice and minimize hallucinations across automated communication channels. Use RAG architectures to structure and unstructured data to automate complex information retrieval tasks.
• API Integration & Automation: Build and maintain robust connections between internal databases, CRM platforms, and third-party AI vendors using REST APIs. Develop Python scripts to automate data entry and reporting workflows, reducing manual operational overhead.
• Data Analysis & Visualization: Aggregate model performance data and business metrics to create comprehensive dashboards and reports using Power BI, facilitating data-driven decision-making for leadership.
• Production Deployment Support: Collaborate with the integration team to support the end-to-end deployment of AI solutions, ensuring systems meet regulatory requirements and service standards before full-scale release.
• Innovation & Trends: Stay current on AI trends and recommend new technologies that could benefit the business and recommend innovations.
• Ethical & Compliant AI Practices: Ensure all AI solutions meet ethical standards, privacy regulations, and uphold our brand’s customer service promise.
• Reporting & Communication: Deliver clear reports and presentations to leadership on project status, outcomes, and strategic recommendations using Power BI, Excel and applicable tools.
