JOB OVERVIEW

______________________________________________________________________________

Sigma Connectivity is seeking a Senior Embedded Android Engineer with proven experience bringing up Qualcomm SoCs and enabling end‑to‑end functionality across the Android platform stack, from Linux device drivers to HALs, native libraries, system services, ART, and Framework APIs. In this role, you will work on new device platforms—mobile, IoT, wearables, and embedded systems—focusing on enabling, optimizing, and debugging connectivity modules, sensors, display, camera, and other core subsystems. You will play a critical role in system‑level stability, performance, and feature enablement across AOSP‑based products for global customers.

Responsibilities:

Lead Qualcomm chipset bring‑up, from bootloader to home screen, including device tree configuration, kernel integration, and subsystem enablement.

Develop, port, and debug Linux device drivers for connectivity (Wi‑Fi/BT/GNSS), sensors (I2C/SPI), display/touch, and camera (MIPI‑CSI, ISP pipeline).

• Implement and customize Android HALs (AIDL/HIDL) across Camera, Sensors, Display, Connectivity, and Power subsystems.
• Develop and maintain native libraries, AIDL interfaces, and Binder IPC services.
• Debug and optimize the ART runtime, JNI layers, native ↔ Java integration, and system performance.
• Enhance and modify Android framework components, system services, and API layers to support new hardware features and OEM customizations.
• Analyze and resolve complex issues across the entire Android stack: kernel logs/dmesg, native services, ART/runtime, system services, and app‑level integration.
• Collaborate cross‑functionally with hardware, design, QA, and customer teams for platform stabilization, feature enablement, and certification readiness.
• Drive CTS/VTS/GTS compliance and debug failures across HAL, framework, and vendor layers.
• Support factory, provisioning, and field diagnostics for production programs..
• Collaborate cross-functionally to deliver reliable and innovative wireless solutions.

Basic qualifications

• Bachelor’s or master’s in computer science, Electrical Engineering, Embedded Systems, or related field.
• 10+ years’ experience in embedded Android platform development.
• Proven experience with Qualcomm chipset bring‑up (QCM/QCS series preferred).
• Strong background in Linux kernel and device driver development for connectivity modules, sensors (I2C, SPI, UART), display & touch, and camera pipelines (HAL3, ISP configuration, sensor modes).
• Expert knowledge of the Android software stack, including Bootloader → Kernel → HAL → Native Services → ART → Framework APIs; AIDL/HIDL, Binder IPC, and JNI.
• Proficiency in C, C++, Java, Kotlin, and Python/Shell scripting.
• Hands‑on experience with AOSP build system, device trees, Soong/Blueprint, and Gerrit workflows.
• Strong debugging skills using logcat, dmesg, Perfetto, Systrace, and kernel tracing tools.
• Familiarity with QCOM tools (QFIL/QPST, Snapdragon Profiler).
• Understanding of system power, thermal states, and performance optimization.

Foundational Android Platform Knowledge (Required)

• Android HAL architecture and its role in hardware abstraction.
• Interaction between kernel drivers, HAL modules, and native services.
• ART runtime behavior, class loading, and JNI interactions.
• AOSP framework's structure, system server, and API surface governance.
• Devices bring up sequences, init/rc configuration, and Android boot stages.
• Differences between kernel driver responsibilities vs HAL responsibilities.
• Sensor delivery pipelines (polling, batching), camera capture paths, and display composition.

Preferred additional skills, personal traits and experience

Personal characteristics:

• Team player
• Proactiveness in collaborating and execution
• Flexibility to switch technical context
• Willingness to learn new methods/tools/processes
