Senior Billing Specialist, New Client Engagements

About the role

We're looking for a Senior Billing Specialist to join our client onboarding team. This is 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.

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

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

Qualifications

• Strong RCM knowledge
• Fast adaptation to unfamiliar systems
• A bias for action
