• Build and ship high-quality patient-facing workflows such as appointment scheduling, care plan tracking, messaging, and other core user experiences.
• Improve mobile application quality and stability by reducing crash rates, improving latency on critical flows, and implementing monitoring, alerting, error tracking, structured logging, and debuggability.
• Extend backend models and GraphQL APIs as needed to support product features while maintaining clean service boundaries and avoiding unnecessary technical debt.
• Ensure secure and compliant handling of sensitive patient data in all feature development, including safe logging, secure data handling, and alignment with HIPAA-conscious engineering practices.
• Contribute to internal clinical workflow tooling and backend services as business priorities shift.
• Work within the architecture established by the Staff App Engineer while identifying and raising opportunities to improve delivery speed, user experience, and technical quality.
• Strengthen day-to-day engineering practices through high-quality code, testing, thoughtful pull request reviews, pairing, and practical improvements to CI/CD and developer experience.
• Partner effectively with product, design, and engineering stakeholders to deliver polished, reliable, patient-facing experiences.

QUALIFICATIONS

• 4 to 7+ years of experience building and shipping production software, with the ability to independently deliver high-quality end-to-end features.
