Flutter Developer

We seeks an experienced Flutter developer to deliver production-grade iOS and Android applications that interface with custom hardware via Bluetooth Low Energy (BLE). The successful candidate will own the full mobile lifecycle, from Figma hand-off through App Store and Google Play approval, while applying sound mathematical reasoning to process device data accurately.

SALARY: PKR 100,000 - PKR 150,000

Key Responsibilities

• Design, develop and maintain Flutter applications for iOS and Android.
• Implement robust BLE connectivity (pairing, data transfer, firmware updates) with external hardware.
• Ensure full compliance with Apple Human Interface Guidelines and Google Play Developer Policies; manage certificates, provisioning and store submissions.
• Translate Figma designs into responsive, accessible UI with consistent performance across devices.
• Apply mathematical and algorithmic techniques to interpret and display sensor data.
• Establish and maintain CI/CD pipelines (e.g., Fastlane, GitHub Actions) for automated builds and releases.
• Write comprehensive unit, widget and integration tests; perform code reviews and produce clear technical documentation.

Essential Qualifications

• Minimum three years of professional experience with Flutter/Dart and at least two published apps on both iOS and Android.
• Proven expertise in BLE integration using libraries such as flutter_blue or flutter_reactive_ble, plus familiarity with CoreBluetooth (iOS) and Android BLE APIs.
• Demonstrated knowledge of App Store Review Guidelines and Google Play policy requirements, including privacy and data-safety disclosures.
• Strong mathematical background (e.g., statistics, signal processing, geometry) with practical application in mobile contexts.
• Proficiency in converting Figma prototypes into high-quality Flutter user interfaces.
• Solid grasp of state-management patterns (Provider, Riverpod, Bloc, etc.), REST/GraphQL APIs and real-time data handling.
• Experience with Git version control and automated build/release workflows.
• Excellent written and verbal communication skills in English.

Preferred Qualifications

• Exposure to IoT or wearable products.
• Knowledge of native Swift or Kotlin, Flutter web/desktop or advanced animation frameworks.
• Familiarity with security best practices and data-protection regulations (e.g., GDPR).
• Contribution to open-source Flutter or BLE projects.
