About Athelas

A patient-centered mindset. You design for the person on the other end of the line, not just the metrics

Responsibilities

  • Design and build backend services in Python that power real-time voice agents, including call orchestration, conversation state, tool execution, and EHR write-back.
  • Architect low-latency pipelines connecting telephony, ASR, LLMs, and TTS into a single conversational loop, ensuring seamless integration and performance.
  • Lead integrations with healthcare systems (like Epic, Cerner, athena, and others) for scheduling, eligibility, and intake, driving design decisions on APIs, data models, and event-driven workflows.

Requirements

  • 4+ years of backend software experience, primarily in Python
  • A track record of designing and shipping production services, APIs, and data models that others build on

Deep experience with async, event-driven, or real-time systems

  • Strong fundamentals in testing, LLM evaluation, observability, and reliability
  • Bias for action, an ownership mindset, and the judgment to know when to move fast and when to slow down
  • An intuition for how people interact with automated assistants through voice and text, where the rules are different than icons and buttons
