StitchFin is redefining what’s possible in healthcare operations. Our agentic AI platform powers autonomous agents (including voice AI) that work across revenue cycle tasks, reducing manual burden, easing staff burnout, and reclaiming millions in lost productivity for healthcare providers. Healthcare is facing a massive labor and efficiency crisis. StitchFin’s platform sits at the intersection of AI, automation, and healthcare infrastructure, and we’re scaling fast. Joining our early team means building product foundations that directly shape how providers get paid and how patients experience care.

Requirements

  • 4+ years of experience building production-grade full stack apps, React, Node.js/Python, PostgreSQL, and modern API design.
  • Experience with real-time or agentic AI systems, voice AI, telephony integrations, or event-driven architectures.
  • Deep familiarity with APIs (REST, GraphQL), queuing/event systems, WebSockets, and cloud platforms (AWS or GCP).
  • Experience in healthcare, revenue cycle, or integrating with EHRs and healthcare data standards (HL7, FHIR, X12, EDI).
  • Background in voice/communication platforms or agent orchestration stacks.
  • Exposure to SOC 2, HIPAA, or other compliance frameworks for secure data environments.
  • Experience scaling early-stage SaaS infrastructure, especially in B2B or healthcare automation environments.

Responsibilities

  • Build the end-to-end agentic AI stack including Voice AI - telephony, speech-to-text, LLM orchestration, text-to-speech, state management, and human-in-the-loop tools.
  • Integrate with major systems of record (EHRs, RCM tools, call center software) to create seamless, secure, and observable workflows.
  • Take full ownership of features, architecture, implementation, deployment, and iteration, with a strong focus on stability and speed.
  • Develop dashboards, configuration tools, and analytics interfaces to manage and tune AI agents in production environments.
  • Work across the full AI agent lifecycle, from voice pipelines to orchestration, real-time analytics, and customer experiences.

Other

  • Prior startup experience where you shipped meaningful features fast, wore multiple hats, and iterated with customers in real time.
  • Strong product sense, curiosity about users, and a willingness to work directly with non-technical customers teams to shape requirements.
  • Partner closely with founders, design, and customers to turn complex healthcare workflows into simple, high-impact product experiences.
  • Location: Remote (USA), must be authorized to work in the US
  • Position Type: Full-time
