About the RoleWe're looking for a Senior Accounts Receivable Specialist to join our client onboarding team - a small group of experienced billers who deploy to new client go-lives, stabilize the engagement, and build the operational playbook that the permanent team inherits.
This is not a traditional billing seat. You'll rotate across clients, specialties, and payer environments. You'll be the first person to work claims in a new client's system, the one who documents what works and what doesn't, and the voice on client calls during the most critical phase of every engagement. You'll pressure-test our AI tooling against real claims and feed specifics back to engineering - not vague feedback, but actionable detail that shapes the product. The role demands deep RCM knowledge, fast adaptation to unfamiliar systems, and a bias for action.
What You'll Do- 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
What We're Looking For- 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
Perks & Benefits- In-person culture at our Flatiron office in NYC with paid lunch and dinner
- Flexible hours and time off
- Gym stipend
- Commuter benefits
- Health, dental, vision insurance
- 401(k) with matching contribution
- Annual offsite
