iOS Engineer

We are seeking a talented iOS Engineer to build and enhance the companion mobile application that serves as the primary interface. This is a highly impactful role involving BLE and Wi-Fi connectivity, real-time device experiences, firmware updates, AI-powered features, and native iOS development. Because the application directly interacts with physical hardware, you will work closely with hardware, firmware, backend, and ML teams. You will own features end-to-end-from architecture and implementation through testing and App Store release-and will have significant autonomy within a small, fast-moving engineering team., * Design and develop BLE and Wi-Fi pairing and connectivity flows, including reconnection and background connectivity.

• Build reliable mechanisms for delivering firmware updates through the iOS application.
• Develop low-latency, responsive UI experiences that reflect live device state and streaming data.
• Integrate on-device and cloud-based AI capabilities into the companion application.
• Design application architecture for device state management, synchronization, offline functionality, and degraded connectivity.
• Implement and optimize native iOS capabilities, including:
• Background modes
• Push notifications
• Bluetooth permissions
• Battery efficiency
• Application performance
• Own features through the complete development lifecycle, including architecture, development, testing, deployment, and App Store release.
• Collaborate cross-functionally with hardware, firmware, backend, and machine learning teams.
• Operate independently and effectively within a small engineering organization.

• Strong hands-on experience with Swift and SwiftUI/UIKit building and shipping production iOS applications.
• Experience with Core Bluetooth (BLE) and/or real-time data streaming.
• Demonstrated ability to own features end-to-end, from architecture through App Store release.
• Experience collaborating with hardware, firmware, backend, and/or ML engineering teams.
• Strong problem-solving skills with the ability to work independently in a fast-paced, small-team environment.
• Proven experience developing and maintaining production-quality iOS applications., * Experience building hardware-connected companion applications.
• Experience with IoT devices, wearables, or other connected hardware products.
• Experience working at a startup or growth-stage company.
• Experience working in small, highly autonomous engineering teams.
• Personal projects, side builds, or open-source contributions demonstrating strong iOS development skills.
