Senior Billing Specialist, New Client Engagements

About Amperos 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. If you want to work on hard problems that matter, alongside people who care deeply about the mission (and each other), we'd love to meet you. About the Role We're looking for a Senior Billing 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 elevate 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 Our Values Lead with Empathy - Great products and teams are built on empathy—whether for our customers, users, or team members. We take the time to walk in others' shoes, listen actively, and truly understand their challenges, needs, and perspectives. Humbly Ambitious - We combine humility with ambition. No task is beneath us, and no challenge too big. Greatness comes from being willing to do whatever it takes, while having the courage to take bold risks and learn from failures. Radical Agency - Own your domain. Drive initiatives with autonomy and accountability. Think deeply, communicate with the team, and maintain a bias for action. #J-18808-Ljbffr Amperos Health Inc.
