Payment Posting Specialist

Amperos is healthcare's first AI-native denial management and revenue recovery platform. Our agentic AI works claims end-to-end, from portal follow-ups and payor calls to appeals and medical records, so providers can resolve more denials, recover more revenue, and focus on what matters most: serving patients.

We just closed a $16M Series A led by Bessemer Venture Partners, with continued participation from Uncork Capital and Neo. We're still small, still early, and going after a $260B+ problem that's only getting worse.

• Flag denials and route them to the appropriate follow-up queue with clear notes

• Track unapplied cash, payment variances, and posting errors through resolution

• Maintain organized documentation of all payment-related activity

What we're looking for

• 2 to 4 years of experience in medical billing, payment posting, or cash reconciliation

• Strong working knowledge of ERA/EOB interpretation, CARC/RARC codes, and adjustment types

• Experience with leading PM systems, including NextGen, ModMed, Athenahealth, and more

• Solid understanding of payer remittance workflows, patient responsibility, and secondary billing

• Ability to spot underpayments, incorrect adjustments, and posting discrepancies

• Detail-oriented, organized, and reliable in documentation and follow-through

• Ability to work US hours (9am to 6pm ET) to collaborate with our team and customers

• Comfortable working in a fast-paced environment where processes and priorities can change
