AI / Machine Learning Talent

About the role

AI Lab - AI/ML Opportunities Location: San Jose, CA (Hybrid - Onsite 3x per week on Tues, Wed, Thurs) About Ensemble's AI Lab Ensemble Health Partners is the leading Revenue Cycle Management (RCM) partner to U.S. health systems. We sit between hospitals, payers, and patients, and we are responsible for billions of dollars of healthcare revenue moving accurately and on time. AI is increasingly central to how we do that work - from predicting denials and automating coding to flagging payment integrity issues and routing accounts to the right action at the right time. These roles exists where those AI systems meet the business outcomes we are paid to deliver. We are continuously building a pipeline of exceptional AI/ML talent across research, data science, and engineering. This general application allows candidates to be considered for multiple roles across the AI Lab. Final role alignment (e.g., Data Scientist, AI Research Scientist, Machine Learning Engineer) and leveling will be determined based on interview performance, experience, and team needs.

Responsibilities

• Depending on your background and strengths, you may:
• Design, build, evaluate, and improve machine learning and AI systems in production environments
• Translate business problems into AI/ML solutions and measurable outcomes
• Develop and run experiments to evaluate models, including defining metrics, datasets, and success criteria
• Productize models into scalable, reliable, and cost-efficient services
• Optimize training and inference performance (latency, throughput, cost)
• Analyze real-world system behavior and production data to drive continuous improvements
• Partner cross-functionally with engineering, product, and domain experts to deliver end-to-end solutions
• Contribute to AI research, experimentation, and adoption of new techniques where applicable
