Denials / AR Follow-up Specialist (Contract, Remote)

Pay: $50–$65/hr

Commitment: Flexible, typically 10–20 hours per week

Patronus AI is a frontier lab building simulation research and infrastructure to accelerate progress toward human-aligned AGI. We built some of the earliest research in AI evaluation, including FinanceBench, Lynx, SimpleSafetyTests, CopyrightCatcher and Humanity's Last Exam. Our team comes from Meta AI, Amazon AGI and Google. Our customers include foundation model labs and Fortune 500 companies, and we are backed by Lightspeed Venture Partners, Notable Capital and others.

We're looking for denials and AR follow-up specialists who do this work today. In your role you work denial and AR queues, write appeals, apply payer policy and timely filing rules, and decide when to rebill, appeal or write off. You'll help us show frontier AI models how that work is really done, and where they get it wrong. You don't need an AI background.

What you'll do

• Explain how the work is done in your role: the steps, the documents, who decides what, and where things go wrong.
• Review realistic task packets, such as denial queues, appeal letters, ERA and EOB remits, 835 and 837 files, payer policy excerpts and write-off decisions, and flag anything a practitioner would find unrealistic.
• Write scoring rubrics precise enough that two independent reviewers reach the same verdict.
• Create new, original tasks from fictional scenarios, solve them yourself and document your reasoning.
• Work independently and asynchronously, meet agreed deadlines and work in reviewer feedback.
