Job description

We are seeking a full-stack connected device engineer who is equally comfortable writing bare-metal firmware on ARM Cortex-M microcontrollers and building polished mobile applications on Android and iOS. You will own the complete software stack-from low-level firmware and wireless protocols to intuitive mobile experiences that interact seamlessly with connected hardware., + 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.

Security, Compliance & Production

Implement secure embedded and mobile systems

Requirements

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.
