Senior Full Stack React Native Developer

Senior Full Stack React Native Developer

We're looking for a Senior Full Stack React Native Developer who can own mobile app development end to end - from architecture and coding through to App Store and Play Store deployment — for both Android and iOS. You'll be the primary (or founding) mobile engineer, so you should be comfortable working with minimal hand-holding, making architectural calls, and also contributing on the backend/API side where needed to keep the mobile experience unblocked.

This is a hands-on, high-ownership role, not a pure specialist seat — you'll work closely with product, clinical operations, and our CRM/backend engineering functions.

What You'll Do

• Own the full lifecycle of our React Native mobile apps — architecture, development, testing, release, and post-launch support — across iOS and Android from a single codebase where practical.
• Design and build patient-, caregiver-, and field-clinician-facing app experiences: scheduling, visit tracking, vitals/care updates, notifications, and similar home-care workflows.
• Build and consume APIs that connect the mobile app to backend systems, including our CRM (Zoho, with Deluge-scripted workflows) and our clinical/EMR backend (Medplum, FHIR-based), so patient and visit data flow cleanly between systems.
• Handle end-to-end deployment: app signing, provisioning, CI/CD pipelines, App Store and Google Play submission, versioning, and release management.
• Implement secure handling of clinical and personal data on-device and in transit, in line with healthcare data-privacy expectations.
• Own app performance, crash-free rates, offline behaviour, and sync reliability — home-care usage often means patchy connectivity in the field.
• Set up and maintain testing practices (unit, integration, and device testing across OS versions/screen sizes) and basic monitoring/analytics (crash reporting, usage tracking).
• Collaborate directly with founders/leadership on product decisions, given the flat structure of the team.
• Mentor junior developers as the mobile team grows.

What We're Looking For

• 5+ years of professional software development experience, with 3+ years building and shipping production React Native apps on both iOS and Android.
• Proven track record of taking at least one app through full deployment — App Store/Play Store submission, review process, and post-launch releases — not just development in a sandbox.
• Strong JavaScript/TypeScript fundamentals, with solid understanding of native modules/bridging when React Native alone isn't enough.
• Full-stack capability: comfortable building or integrating REST/GraphQL APIs and working with a backend (Node.js preferred, but adaptable).
• Experience with CI/CD for mobile (Fastlane, EAS, App Center, or similar) and release/versioning discipline.
• Familiarity with mobile security and data-privacy practices; healthcare or other regulated-data experience is a strong plus.
• Comfortable working with third-party/CRM integrations and, ideally, some exposure to FHIR/HL7 or EMR-adjacent systems (not mandatory, but valuable given our stack).
• Startup/scale-up mindset: able to work independently, prioritize pragmatically, and move fast without sacrificing code quality.
• Strong communication skills — this role works directly with leadership and cross-functional teams, not just other engineers.

Nice to Have

• Experience with Expo (managed or bare workflow).
• Exposure to offline-first app architecture and data sync strategies.
• Prior experience in healthcare, home care, or another operationally complex, field-force-driven business.
• Experience setting up a mobile app from zero to one (greenfield build).

Why Join

• High-ownership role with direct influence on product and architecture decisions from day one.
• Work on technology that has a direct, tangible impact on patient care.
• Close collaboration with senior leadership across business and technology.
• Opportunity to shape the mobile engineering practice as the team scales.
