  • Integrate with backend services built in Ruby on Rails
  • Debug and resolve production issues with a strong sense of ownership and urgency

Skills, Knowledge and Experience
Requirements
  • 7+ years of professional software engineering experience
  • 4+ years of hands-on experience building and maintaining production Flutter applications
  • Proven experience shipping apps on iOS and Android
  • Strong understanding of modern Dart and Flutter
  • Ability to ramp quickly in an existing codebase and contribute independently
  • Comfortable owning large features or systems end-to-end
  • Strong collaboration skills across engineering, product, and non-technical stakeholders
  • Experience working in fast-paced startup environments with high ownership
  • Product-minded engineering approach: You have the UI/UX intuition to make sound design decisions and polish workflows.
Nice to Have
  • Experience in healthcare or regulated environments
  • Experience building workflow-heavy or operationally complex applications
  • Experience designing for low or unreliable connectivity environments
  • Barcode scanning or camera-based integrations
  • Familiarity with Ruby on Rails backend systems
  • Experience with AWS or cloud infrastructure
  • Experience with Flutter web
  • Familiarity with the Maestro test framework
What Success Looks Like
  • You are contributing meaningful production code within your first few weeks
  • You take ownership of core mobile features and drive them to completion
  • You improve the reliability and usability of workflows used daily by care teams
  • You proactively identify and solve technical challenges in the mobile stack
  • You operate with a high degree of autonomy while collaborating effectively with the team

Benefits

  • Competitive compensation aligned with experience
  • 100% company-paid medical coverage (base plan)
