## Job description

## 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 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

## 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.

## About Amperos

## Company Overview
- **One-liner**: Amperos uses agentic AI to automate end-to-end insurance revenue recovery for healthcare providers, from denial management to collections.
- **Entity Type**: Private (Series A, raised $16M in April 2026)
- **Headquarters**: New York City, United States
- **Founded**: 2023
- **Founders**: Michal Miernowski (CEO & Co-Founder), Wilson Wang (CPO & Co-Founder), Alvin Wu (CTO & Co-Founder)

## Core Business
- **Primary industry**: Healthcare Revenue Cycle Management (RCM), specifically denial management and insurance collections.
- **Target customers**: B2B – outpatient healthcare providers, including independent practices, clinics, and larger health systems.
- **Mission**: To help healthcare teams recover the revenue they’ve already earned, so providers can focus on operating their practices and serving patients.

## Products & Services
- **AI-Native Denial Management Platform**: Agentic AI that handles the full denial workflow – payer portal follow-ups, phone calls, corrected claims, medical records submissions, and appeals – with no handoffs. Escalates complex cases to Amperos’ RCM experts.
- **Insurance Collections Outsourcing**: End-to-end management of the collections process, from first-touch denials to complex escalations, using AI agents and human oversight.
- **Workflow Configuration & Analytics**: Customizable workqueues, SOP mapping, and real-time dashboards that provide visibility into claims pipeline, recovery rates, and root-cause insights.

## Market Standing
- **Valuation/Market Cap**: Not disclosed.
- **Key Metric**: Total funding of $20.2M ($4.2M seed in June 2025 + $16M Series A in April 2026). The company has recovered over $700M in outstanding claims annually across 500,000+ claims and 3,000 clinical locations in all 50 states.
- **Notable Investors/Partners**: Bessemer Venture Partners (lead Series A), Uncork Capital, Neo. Angel investors from OpenAI, Stripe, and others. Integrates with EHRs including eClinicalWorks, Athenahealth, NextGen, Epic, ModMed, Dentrix.
- **Growth Signals**: 255.6% year-over-year headcount growth (25 employees as of mid-2025), monthly job postings up 66.7%, quarterly up 150%. Launched the industry’s first AI-native denial management platform in April 2026. Customers see 22% more recovered per claim at up to 50% lower cost to collect.

## Competitive Advantages
- **End-to-end automation**: Unlike competitors that automate only parts of the denial process (e.g., calling or letter writing), Amperos handles the entire workflow – from portal navigation to appeals – with AI agents that use LLMs across voice, computer use, and more.
- **Proven outcomes**: 22% higher recovery rates and 50% lower cost to collect compared to traditional or manual processes.
- **Expert overlay**: A team of tenured RCM specialists provides judgment on the hardest claims, combining AI speed with human expertise.
- **HIPAA-compliant and bank-level security**: Fully compliant with healthcare data regulations.

## Strategic Focus
- **Scale and expand**: Use the $16M Series A to accelerate growth, serve more providers, and expand analytics capabilities.
- **New agentic workflows**: Launch additional AI-native capabilities in other RCM workflows beyond denial management.
- **Prevention insights**: Deliver detailed analytics that help providers optimize billing and collections processes to prevent future denials.

## Why Work Here
- **Culture**: In-person culture based in NYC with flexibility when needed. Values include “radical agency” (deep autonomy and accountability) and “lead with empathy.”
- **Benefits**: Medical, dental, and vision premiums paid in full for employees and dependents; 401(k) with 4% match; flexible time off plus 14 company holidays; pre-tax commuter benefits; meals provided on office days; gym stipend; budget for tools and gear; regular company offsites.
- **Engineering & team**: Technical team makes up 22% of staff. Strong talent pipeline from companies like Dropbox, McKinsey, R1 RCM, and Ardea Partners. Headcount growing rapidly (+255% YoY).
- **Open roles**: 5 active positions as of mid-2025, including Billing Associate, Senior RCM Specialist, AI Deployment Strategist, and Enterprise Account Executive.
