Applied AI Engineer

Exactrx builds AI agents to automate medical billing for healthcare providers. The Applied AI Engineer will develop and operate AI agents for coding claims, payer-rule checks, and customer analytics, while evaluating and improving production performance.

Responsibilities:

• Build and improve LLM-driven agents that read clinical documentation and assign CPT, ICD-10, and modifier codes
• Turn payer rules and published policies into claims checks that run before submission, and grow our claim rules library as new denials appear
• Build evaluation loops from coder feedback, remittance data, and production traces to measure accuracy, catch regressions, and choose between prompting, retrieval, rules, and fine-tuning
• Analyze claims data for new customers to determine drivers of AR days and denials in dollars, and build report cards for our sales team
• Track performance after go-live
