Senior React Native Engineer

Job Responsibilities:

• Design, build and ship features end-to-end in the Maydon Rent mobile app (iOS + Android) for both Tenant and Owner experiences, owning code from API integration to release.
• Maintain and evolve the Feature-Sliced Design + Modular Monolith architecture, enforcing FSD layer boundaries and module public APIs; review PRs to prevent architectural drift.
• Build and integrate features against the four-microservice REST backend (identity, buildings, commons, listings) using axios + TanStack React Query, including query-key factories, cache invalidation policies and optimistic updates.
• Implement and harden secure flows: OneID/MyID onboarding, E-IMZO digital signature, token refresh queue, biometric + PIN App Lock with progressive lockout and OWASP MASVS controls.
• Write, integrate and debug native modules (Swift/Kotlin) and Nitro modules; troubleshoot New Architecture (Fabric/TurboModules) issues; manage CocoaPods, Gradle flavors and signing.
• Build complex animated UI with Reanimated 4, Gesture Handler, Skia and @gorhom/bottom-sheet; ensure 60 fps on mid-range Android.
• Profile and optimize performance (Hermes, list virtualization, image pipeline with FastImage/Blurhash, bundle size, startup time) and memory/leaks.
• Own quality gates: TypeScript strictness, ESLint FSD boundaries, dependency-cruiser, Jest unit tests, i18n & icon validators, GitHub Actions CI.
• Keep the OpenAPI → TypeScript code-generation pipeline (@hey-api/openapi-ts) healthy and align with backend contracts.
• Ship localized (ru/uz/en) and responsive (phone/tablet) UI; collaborate with design on the design system and Storybook.

Education:

• Bachelor's degree in Computer Science, Software Engineering, or a related technical field. Equivalent practical experience is acceptable for outstanding candidates.

Work Experience:

• 6+ years of professional software engineering experience overall.
• 5+ years of production React Native experience, with at least one app shipped to App Store and Google Play and maintained through multiple release cycles.
• Hands-on experience with React Native 0.7x+ and the New Architecture (Fabric / TurboModules / Hermes). Bonus for 0.80+ and Nitro modules.
• Proven experience designing or maintaining a modular or Feature-Sliced React Native codebase (>500 files, multiple feature teams).

Hard Skills

• Expert TypeScript (5.x): generics, discriminated unions, strict mode, designing typed public APIs and barrel exports.
• React 18/19 patterns: hooks, Suspense, concurrent rendering, memoization and re-render profiling.
• React Native runtime knowledge: bridge vs. JSI, Hermes, Fabric/TurboModules, Reanimated worklets, threading model.
• React Navigation v7 (native-stack, bottom-tabs, drawer), deep linking and push-notification routing.
• TanStack React Query 5 (key factories, invalidation, optimistic updates, infinite queries) and axios interceptors with concurrent-safe token refresh.
• Native build tooling: CocoaPods, Xcode schemes/configurations, Gradle build flavors, code signing for both stores.
• Ability to write and debug Swift/Objective-C and Kotlin/Java at the level needed to integrate, fix or wrap native SDKs.
• Animation & complex UI: Reanimated 3/4, Gesture Handler, Skia, @gorhom/bottom-sheet, keyboard controller.
• Forms & validation: react-hook-form + zod/yup, masked/phone inputs, OTP fields.
• Storage & security: Keychain/Keystore, MMKV, certificate pinning, biometric APIs, OWASP MASVS basics.
• Testing: Jest unit testing, snapshot/component testing, mocking native modules.
• Tooling: ESLint flat config, Prettier, dependency-cruiser, OpenAPI codegen (@hey-api), Storybook on-device, Reactotron.
• Git, GitHub Actions CI, semantic PRs, conflict resolution.
• Expert at Clean code principles

Soft Skills:

• Strong written and verbal communication in Uzbek and/or Russian, plus working English for technical reading and async written collaboration.
• Ownership mindset — drives features from spec to production without hand-holding.
• Pragmatic decision-making: knows when to abstract vs. duplicate, when to add a dependency vs. write it, when to ship vs. polish.
• Code-review craft: gives clear, kind, actionable feedback; receives it without ego.
• Mentorship and willingness to document decisions for the team.
• Reliable self-management in a remote/hybrid setup; raises blockers early.

Desirable Criteria:

• Experience with E-IMZO, OneID/MyID or other Uzbek/CIS digital-identity stacks.
• Experience integrating biometric + PIN app-lock flows compliant with OWASP MASVS.
• Experience writing Nitro modules or other JSI-based native modules.
• Experience with mapping SDKs (Yandex/Google/Mapbox/Nitro Maps) and geolocation flows.
• Experience designing or maintaining OpenAPI → TypeScript code-generation pipelines.
• Experience with App Store Connect, Google Play Console, phased rollouts, crash analytics (Sentry/Firebase Crashlytics) and OTA updates.
• Real-estate, marketplace or two-sided product domain experience.
• Past public RN OSS contributions or conference talks.
