Full Stack Software Developer

Synapsis Technologies builds AI‑enabled health apps and connected experiences that help people understand and improve their health. Our portfolio includes mobile and web applications for wellness, women’s health, and clinical workflows. We integrate with wearables, medical devices, and third‑party platforms while maintaining rigorous privacy and security standards.

React Native (iOS/Android), React for Web, and Progressive Web Apps (PWA)

• Build and maintain cross‑platform

  React Native

  apps (Expo or bare), responsive

  web apps

  (React/Next.js), and

  installable PWAs

  (service workers, offline cache, background sync).
• Integrate multiple APIs (REST/GraphQL); handle auth flows (OAuth2/OIDC), token refresh, pagination, retries, and client‑side caching.
• Design and implement

  Role‑Based Access Control (RBAC)

  and permissions (e.g., Keycloak/Auth0/Custom), including protected routes, feature‑flagged UIs, and audit‑friendly patterns.
• Collaborate with product/design to scope features; own components, screens, and data flows end‑to‑end.
• Write high‑quality TypeScript, unit/integration tests (Jest, React Testing Library), and E2E tests (Playwright/Detox).
• Optimize performance (virtualized lists, memoization, bundle/profile analysis) and accessibility (WCAG 2.1 AA best practices).
• Ship via CI/CD (Fastlane/EAS/GitHub Actions) to App Store/Play Console and web environments.
• Contribute to secure‑by‑design practices (input validation, secrets handling, least‑privilege access, data minimization).

• 3–4 years

  building production React/React Native apps with

  TypeScript

  .
• Proven experience delivering

  responsive

  UIs for

  mobile and web

  , including PWAs.
• Solid API integration skills across multiple providers; comfortable with REST/GraphQL, WebSockets, and offline‑first patterns.
• Hands‑on with

  RBAC/authorization

  (route guards, role/permission checks, server‑driven policy, token management).
• Strong state/data management:

  React Query/TanStack Query

  , Redux Toolkit, Zustand, or equivalent.
• Testing mindset with practical coverage (unit, integration, E2E) and CI familiarity.
• Ability to decompose complex requirements, communicate trade‑offs, and ship incrementally.

• Next.js (SSR/ISR), Vite build tooling, and Tailwind CSS.
• Expo (EAS), native modules/bridging, and mobile performance profiling.
• Experience with one or more auth stacks: Keycloak, Auth0, Cognito, Firebase Auth.
• Knowledge of healthcare privacy and compliance (e.g.,

  PIPEDA

  , SOC 2), basic familiarity with FHIR/HL7 or wearable SDKs.
• Analytics and experimentation (feature flags, A/B testing, Amplitude/GA4, Segment).
• Experience in design systems or component libraries (Storybook, Radix UI).

• Frontend:

  React, React Native, TypeScript, Next.js, Tailwind, PWAs (Workbox)

• Data/State:

  React Query/TanStack Query, Redux Toolkit/Zustand

• Auth/RBAC:

  OAuth2/OIDC, JWT, Keycloak/Auth0 (or similar)

• Testing/CI:

  Jest, React Testing Library, Playwright/Detox, GitHub Actions, Fastlane/EAS

• APIs/Realtime:

  REST, GraphQL, WebSockets

• Small, fast, and product‑driven teams with clear ownership and frequent releases.
• Design partnerships with clinicians and wellness experts; user research informs roadmap.
• Pragmatic engineering: shipping reliable, secure features with a focus on impact.

• Competitive compensation with performance growth.
• Meaningful work in digital health with real‑world user impact.
