About the role

Mission-critical problem: Healthcare communication failures affect millions daily—your work directly powers systems patients and providers rely on. High ownership and agency—you thrive in ambiguity and take responsibility for system outcomes.

What they're looking for

  • 5+ years of experience designing, building, and scaling backend systems in high-reliability production environments
  • Strong backend expertise across APIs, relational databases, async workflows, and distributed systems
  • High ownership and agency—you thrive in ambiguity and take responsibility for system outcomes

  • Bonus: experience with security, auth, or regulated environments (HIPAA familiarity is a plus)
  • You’ll be a great fit if you enjoy owning critical backend systems end-to-end, solving complex problems under real-world constraints, and building infrastructure that directly impacts patient care
