Careers at MedXFlow
MedXFlow is building the AI agents that run the healthcare revenue cycle - eligibility, prior authorization, coding, claims, denials and collections - backed by certified RCM experts. We hire people who want their work measured in claims paid and denials prevented, not slides. Remote-first across the US, with a bias for ownership and craft.
10 open roles
Generative AI Specialist (Revenue Cycle)
AI & Engineering · Full-time · Remote (US) · 4+ years
Design and ship the AI agents that work real revenue cycles, not demos. You own an agent end to end - prompt and tool design, evaluation, guardrails, and the human-escalation loop - against live payer portals and EHRs.
What you will do
- Build production AI agents for eligibility, prior authorization, coding and denials that complete tasks end to end.
- Design robust tool-use, retrieval and evaluation harnesses; measure agents on outcomes (claims paid, denials prevented), not vibes.
- Own guardrails, auditability and the escalation path so every action is safe, logged and reviewable.
- Partner with certified coders and billers to encode real payer rules into agent behavior.
What we are looking for
- Hands-on experience building LLM-based agents or applications in production.
- Strong Python and prompt/eval engineering; comfort with tool-use, RAG and structured outputs.
- A bias for shipping and measuring; you instrument everything.
- Bonus: healthcare, RCM, EDI or claims experience.
AI / ML Engineer (Healthcare)
AI & Engineering · Full-time · Remote (US) · 5+ years
Build the models and data pipelines behind the agents: document extraction from EOBs and 835s, denial classification, and the evaluation infrastructure that keeps quality high as we scale.
What you will do
- Build extraction and classification models for remittances, denials and clinical documents.
- Own data pipelines and the offline/online evaluation that gates every model change.
- Ship low-latency inference services that agents call in real time.

What we are looking for
- 5+ years in ML engineering with production models, not just notebooks.

- Bonus: healthcare data (HL7/FHIR, X12 EDI) experience.
