Senior Mobile Engineer Cross-Platform

Revelation Pharma LLC•Remote, US,

6d•$130,000 - $155,000•Remote

About The Position

Evergreen Telehealth is a vertically integrated direct-to-consumer telehealth platform under Revelation Pharma Corporation. We are building Grove, an AWS-native, FHIR R4-first clinical platform. The mobile patient experience is the front door to that platform, and it needs to be built right. We are hiring a Senior Mobile Engineer to own and evolve the Grove patient-facing mobile application. The app is currently in active development and your immediate job is to absorb the existing codebase, establish architecture standards, and take ownership of the mobile layer as a domain authority. This is a cross-platform role. We are building for iOS and Android from a shared codebase. The candidate must be fluent in React Native or Flutter and comfortable operating as the sole internal mobile authority in close collaboration with an offshore development team.

Requirements

4+ years of production mobile engineering experience with React Native or Flutter — shipped apps, not prototypes
Strong cross-platform discipline — understands the tradeoffs between shared code and platform-native behavior, and knows when to break the abstraction
Experience consuming REST and FHIR APIs from mobile — pagination, error handling, token refresh, offline caching
AWS Cognito or equivalent identity/auth integration in a mobile context — token management, MFA, session handling
HIPAA-aware mobile development — secure local storage, PHI handling constraints, screenshot/clipboard controls
App Store and Google Play deployment experience — provisioning profiles, signing, phased rollouts, rejection handling
Experience working with an offshore or distributed engineering team — asynchronous collaboration, PR review, design documentation

Nice To Haves

Prior experience building telehealth, healthcare, or patient-facing clinical apps
Familiarity with FHIR R4 data structures — Patient, Observation, MedicationRequest, CarePlan resources
Experience integrating LLM or AI agent response surfaces into a mobile UI (chat, structured guidance, goal tracking)
Expo or bare React Native workflow experience; Fastlane or equivalent CI/CD for mobile
Comfort reading and reviewing TypeScript/Node.js backend code to coordinate API contracts with the backend team
Understanding of accessibility standards (WCAG 2.1 AA) for patient-facing healthcare apps

Responsibilities

Grove patient mobile app — architecture, codebase standards, and ongoing feature development across iOS and Android
Onboarding and intake flows — patient registration, identity verification, consent management, and Cognito-based authentication
Clinical UX surfaces — symptom intake, medication status, refill requests, care plan display, and AI agent interaction surfaces
FHIR R4 data consumption — rendering patient records, care timelines, and clinical summaries from AWS HealthLake via the Grove API layer
Push notifications, deep linking, and offline-tolerant state management for a patient population with variable connectivity
Canvas Medical patient portal integration — rendering clinical data surfaced via Canvas APIs within the mobile experience
App Store and Google Play deployment pipeline — CI/CD, release management, versioning strategy
Technical handoff and standards-setting with the KMS Technology mobile team — code review, architecture review, PR standards
