Senior Embedded IoT & Android/iOS Engineer

Key Responsibilities

• Firmware & Wireless Systems
• Develop production-grade firmware for ARM Cortex-M MCUs, including RTOS integration, peripheral drivers, low-level bring-up, and power optimization.
• Design and implement wireless communication stacks: BLE (GATT/GAP), Wi-Fi, and cellular (LTE-M / NB-IoT).
• Build secure OTA update mechanisms with rollback protection and cryptographic validation.
• Integrate device-side IoT protocols (MQTT, CoAP) with cloud platforms such as AWS IoT Core.
• Collaborate with hardware teams on board bring-up, debugging, and system validation.
• Mobile Applications (Android & iOS)
• Design and develop native Android (Kotlin/Java) and iOS (Swift) applications for connected devices.
• Implement device discovery, provisioning, BLE/Wi-Fi pairing, and real-time communication with firmware.
• Architect scalable mobile apps using modern patterns:
• Android: MVVM, Coroutines, Jetpack
• iOS: MVVM/Combine/SwiftUI or UIKit
• Ensure robust connectivity handling, background execution, and reconnection strategies across diverse devices.
• Deliver OTA firmware updates through mobile apps.
• Cloud & IoT Integration
• Design end-to-end connectivity between device, mobile apps, and cloud services.
• Integrate with AWS IoT services (IoT Core, Device Shadow, MQTT broker, OTA services).
• Build secure device provisioning and authentication workflows.
• Collaborate on backend APIs and data pipelines supporting connected products.

Required Qualifications

• 5+ years of embedded firmware development on ARM Cortex-M (or similar).
• Proven experience shipping BLE-connected IoT products end-to-end.
• Strong programming skills in:
• C/C++ (embedded)
• Kotlin and/or Java (Android)
• Swift (iOS)
• Hands-on experience with BLE, Wi-Fi, and at least one cellular technology.
• Experience with AWS IoT or similar cloud IoT platforms.
• Deep understanding of secure device design (secure boot, OTA, encryption, key provisioning).

Preferred Qualifications

• MS or PhD in Computer Engineering, Electrical Engineering, or related field.
• Experience with Rust in embedded systems (e.g., Embassy framework).
• Familiarity with AOSP, embedded Linux (Yocto/Buildroot).
• Experience in regulated environments (FDA, ISO 13485, IEC 62304).
• Proven track record of taking IoT products from prototype to volume manufacturing.
• Experience building cross-platform mobile architectures or shared SDKs.
