Senior Billing Specialist, New Client Engagements

Amperos•New York, NY

6d•$65,000 - $90,000•Onsite

About The Position

Amperos is seeking a Senior Billing Specialist to join their client onboarding team. This role involves deploying to new client go-lives, stabilizing engagements, and building operational playbooks for permanent teams. Unlike traditional billing roles, this position requires rotating across clients, specialties, and payer environments. The specialist will be the first to work claims in new client systems, document effective processes, and communicate with clients during critical phases. A key aspect of the role is pressure-testing Amperos's AI tooling against real claims and providing detailed, actionable feedback to the engineering team. The position demands deep RCM knowledge, rapid adaptation to unfamiliar systems, and a proactive approach.

Requirements

5+ years of hands-on experience in insurance eligibility and verification, medical billing, AR follow-up, and denial management
Direct experience working in a hospital system or physician practice — you've worked claims from inside a provider environment
Deep working knowledge of payer portals, clearinghouse workflows, and at least two practice management systems
Demonstrated expertise in denial resolution across multiple categories: authorization, medical necessity, timely filing, COB, coding
Experience with appeals processes including writing appeal letters and compiling supporting documentation

Responsibilities

Deploy to new client go-lives and work claims end-to-end in the client's PMS and the Amperos workqueue from day one
Participate in client onboarding calls and provide claim-level feedback on workflows and tooling
Bridge the production gap while permanent associates ramp to full capacity
Work across multiple practice management systems and payer portals with minimal ramp time
Identify gaps in client-provided SOPs and escalate with specific recommendations
Execute claim follow-up, denial resolution, appeals, and payer calls per client-specific SOPs
Document every workflow, exception, and payer-specific nuance — these become the SOPs and training materials for the permanent team
Pressure-test Amperos's AI agents against real claims and surface product issues to engineering with enough detail to act on immediately
Conduct QA reviews of permanent BA work during the transition and flag quality gaps before the team exits the engagement
