Purpose of the Role The Flutter Developer (Mobile, SDK & Web) is the hands-on engineering owner of the Connected Cars Platform's cross-platform client layer — responsible for designing, building, and maintaining Flutter-based mobile applications, reusable SDKs, and progressive web interfaces that deliver the vehicle owner experience across Android, iOS, and browser targets.

The role covers the complete client-side engineering lifecycle: translating product and UX wireframes into pixel-perfect, performant Flutter interfaces; developing and publishing platform-agnostic Dart SDKs consumed by first-party apps and third-party integrators; integrating with secure REST and gRPC APIs backed by OpenAPI specifications; and implementing robust authentication and authorisation flows including OAuth 2.0, OIDC, and deep-link-based vehicle login. The engineer also maintains native bridging layers on Android and iOS where Flutter's plugin ecosystem does not cover platform-specific capabilities.

Job Responsibilities:

Flutter Application Development:

- Architect and develop production-grade Flutter applications targeting Android, iOS, and web from a single codebase, maintaining platform-specific fidelity where required.
- Implement complex, stateful UI using Flutter's widget tree, Riverpod / BLoC / Provider patterns, and declarative navigation with GoRouter or auto_route.
- Build and publish reusable Dart packages and Flutter SDKs — covering connectivity, telemetry consumption, remote command dispatch, and authentication — consumed internally and by third-party integration partners.
- Develop Flutter Web builds deployed as progressive web apps (PWA) with offline capability, deep-link routing, and responsive layouts across breakpoints.
- Integrate platform channels and method channels to bridge Flutter with native Android (Kotlin/Java) and iOS (Swift/Objective-C) device APIs — Bluetooth, push notifications, keystore access, and background services.
- Maintain CI/CD pipelines (Fastlane, Codemagic, or GitHub Actions) for automated build, test, and distribution across Play Store, App Store, and internal MDM channels.
- Write and maintain unit, widget, and integration tests achieving defined coverage thresholds; participate in peer code reviews and enforce Flutter/Dart best practices.

UI/UX Engineering & Design System:

- Collaborate with UI/UX designers to translate Figma specifications into Flutter widgets with sub-pixel accuracy, consistent motion, and Material 3 / custom design language compliance.
- Build and maintain a shared Flutter design system — tokens, components, themes — that enforces the brand across all apps and web surfaces.
- Implement responsive and adaptive layouts for varied screen densities, aspect ratios, and input modalities (touch, rotary, voice) including in-vehicle IVI targets.
- Apply accessibility standards (WCAG 2.1 AA) across all Flutter surfaces — semantic labels, screen-reader compatibility, contrast compliance, and keyboard navigation.
- Prototype and validate interaction concepts rapidly using Flutter's hot-reload environment, gathering feedback from UX researchers and product owners before production builds.
- Instrument UI performance — frame rates, jank, startup latency — using Flutter DevTools and drive continuous improvement against defined benchmarks.

API Integration, OpenAPI & Security:

- Consume and integrate cloud REST APIs defined by OpenAPI 3.x specifications; generate type-safe Dart client code using openapi-generator and maintain client–server contract alignment.
- Design and implement authentication and authorisation flows — OAuth 2.0 Authorization Code + PKCE, OpenID Connect, device flow (RFC 8628) for in-vehicle login — using flutter_appauth and secure token storage.
- Implement token lifecycle management: silent refresh, revocation, biometric-guarded keychain/keystore storage, and encrypted local persistence (flutter_secure_storage).
- Integrate mutual TLS (mTLS) and certificate pinning for high-assurance channels between the app and the connected vehicle backend.




- Develop secure deep-link and universal link handling for cross-app and in-vehicle IVI launch flows, validating intent origin and preventing open-redirect vulnerabilities.
- Apply OWASP Mobile Top 10 principles across app code: prevent cleartext credential storage, enforce runtime permission checks, obfuscate release builds, and integrate dynamic security scanning in CI.
- Work closely with the cybersecurity team during threat modelling and security design reviews for all new client-facing features.

Native Platform Bridging:

- Write Android platform channel implementations in Kotlin — accessing BluetoothLE APIs, Android Keystore for cryptographic operations, FCM push integration, and foreground service management.
- Write iOS platform channel implementations in Swift — integrating with Keychain Services, APNs, CoreBluetooth, and Background Modes.
- Read and understand native Android Automotive OS (AAOS) app manifests and car-specific APIs where the Flutter app runs in an embedded or companion context.
- Diagnose and resolve native-layer crashes reported via Crashlytics / Sentry, triaging between Dart, JVM, and native stack frames.

Performance, Quality & Observability:

- Define and track app quality KPIs: crash-free session rate, API error rate, cold/warm start time, and widget render budget adherence.
- Integrate Firebase Performance Monitoring and custom traces to surface regressions in CI before reaching production.
- Conduct memory profiling and detect leak patterns in Dart isolates and platform channel callbacks.
- Establish golden-image regression testing for critical UI flows using flutter_test and Patrol.

Collaboration & Process:

- Translate product requirements and UX wireframes into technical specifications, breaking work into Sprint-deliverable tasks with clear acceptance criteria.
- Collaborate with backend engineers to define API contracts via OpenAPI early in the feature lifecycle, preventing late-stage integration rework.
- Contribute to the platform's mobile-first developer experience — SDK documentation, code samples, integration guides — for internal teams and external partners.
- Mentor junior Flutter engineers and enforce code quality through structured pull-request reviews and internal tech talks.
- Participate in the connected car platform's quarterly architecture council to align client-side evolution with platform roadmap.

Desired Candidate Profile:

- B.E. / B.Tech in Computer Science, Electronics, or a related engineering discipline.
- M.E. / M.Tech or relevant professional certifications (Google Flutter Certified, AWS Mobile, CKAD) are desirable.
- Minimum 5 years of total software engineering experience.

- Demonstrated experience shipping Flutter SDK packages to pub.dev or internal package registries.
- Proven track record of integrating OAuth 2.0 / OIDC authentication flows and OpenAPI-specified backend services in mobile or web applications.
- Experience in the automotive, mobility, or connected-device domain is a strong advantage.
