Senior Mobile Developer
Accomplished Tech Visionary:
Elevate your expertise to new heights at 3Pillar, the premier destination for trailblazing senior software engineers like yourself. Picture collaborating with industry leaders, spearheading transformative projects that redefine urban living, establishing new media channels for enterprise companies, or driving innovation in healthcare. Our mission is to revolutionize the tech landscape, and your skills are integral to achieving this ambitious goal.
Your role extends beyond the realm of code composition; you will architect transformative solutions that reshape entire industries. Join us and spearhead the charge toward a tech future that transcends the ordinary.
You will be focused on the development and optimization of mobile applications, orchestrating an AI-accelerated development process. The project's first phase centers on enhancing a dedicated Android-only application, followed by a second phase delivering an application targeting both Android and iOS platforms. Your role is critical in bridging web technologies (Ionic/Capacitor) with complex native device hardware, specifically deep Bluetooth Low Energy (BLE) integrations, fully supported and accelerated by AI tools.
Requirement
Facilitate effective communication with client project stakeholders regarding project status and recommendations.
Act as a force multiplier by orchestrating AI coding tools to rapidly scaffold Capacitor plugin interfaces, boilerplate UI, and test suites.
Review and correct AI-generated code across a multi-language stack (TypeScript, Kotlin, Swift), quickly identifying and rectifying AI hallucinations or deprecated API usage, especially regarding hardware permissions and native interactions.
Architect and build the native bridge allowing the JavaScript WebView to communicate with native hardware seamlessly, handling asynchronous high-frequency data streams (like BLE payloads) without bottlenecking the UI thread.
Lead the Phase 1 Android implementation by developing robust background services, managing complex BLE connections (GAP, GATT, MTU negotiations), and ensuring battery-optimized hardware communication.
Design TypeScript Capacitor interfaces with cross-platform foresight, ensuring the Android API design can be smoothly replicated in Swift/CoreBluetooth during the Phase 2 iOS expansion.
Collaborate with cross-functional teams to deliver a world-class mobile experience.
Stay up-to-date with the latest trends in React Native, TypeScript, Expo and mobile development.
