Role Summary

We are looking for a highly skilled Senior **Lead Engineer – HLOS Platform Software** to design, develop, debug, and optimize Android/Linux-based platform software for advanced mobile and wearable SoCs.

The role requires strong expertise in Linux kernel internals, device-driver development, SoC bring-up, power management, interrupt handling, memory management, peripheral enablement, and hardware/software debugging. The engineer will work close to the hardware boundary and contribute to platform enablement from early silicon or pre-silicon environments through production software maturity.

This is a deeply technical role intended for engineers who enjoy solving complex low-level software problems across the Linux kernel, boot flow, device tree, power frameworks, and SoC peripheral subsystems.

Key Responsibilities

Linux Kernel and Platform Software Development

• Develop, port, and maintain Linux kernel drivers for mobile and wearable SoC platforms.
• Work on Android/Linux HLOS software components including:
  • Kernel board support
  • Device tree configuration
  • Platform drivers
  • Power-management drivers
  • Peripheral interface drivers
  • Kernel configuration and build integration
• Enable new SoC features in the Linux kernel and Android/Linux platform stack.
• Analyze hardware specifications, register descriptions, timing requirements, and programming sequences to implement robust software support.
• Develop low-level software for SoC blocks such as PMIC interfaces, GPIO, pinctrl, clocks, regulators, interrupts, timers, buses, thermal sensors, and peripheral controllers.

Device Driver Development and Debug

• Design and implement production-quality Linux device drivers using standard kernel frameworks.
• Work with Linux subsystems such as:
  • Platform driver framework
  • Device tree
  • Regulator framework
  • Clock framework
  • GPIO and pinctrl framework
  • IRQ subsystem
  • Power supply framework
  • Thermal framework
  • I2C, SPI, UART, USB
  • DMA and memory mapped I/O
  • Runtime PM and system suspend/resume
• Debug driver probe failures, resource dependency issues, interrupt storms, register access failures, race conditions, and timing-related bugs.
• Analyze kernel logs, traces, register dumps, memory dumps, and crash dumps to identify root causes.
• Improve driver robustness for error handling, concurrency, low-power entry/exit, and recovery paths.

SoC Bring-up and Hardware/Software Enablement

• Support platform bring-up across pre-silicon and post-silicon environments such as simulation, emulation, FPGA, development boards, and silicon.
• Debug early boot and kernel initialization issues including:
  • Kernel boot failures
  • Device tree mismatches
  • Clock/regulator dependency failures
  • Interrupt configuration issues
  • Memory-map or access-permission faults
  • Peripheral initialization failures
• Work with bootloader handoff information, kernel command line, memory layout, reserved memory, device tree bindings, and platform configuration.
• Enable basic and advanced SoC functionality from initial kernel boot to stable feature operation.
• Validate hardware programming sequences against SoC documentation and expected behavior.

Power Management and Performance Optimization

• Develop and debug Linux power-management flows for mobile and wearable platforms.
• Work on:
  • Runtime PM
  • System suspend/resume
  • Wakeup-source handling
  • Regulator voting
  • Clock enable/disable sequencing
  • Low-power mode transitions
  • Device idle paths
  • Thermal mitigation behavior
• Debug power-collapse failures, suspend blockers, unexpected wakeups, interrupt wake issues, regulator/clock vote leaks, and low-power transition failures.
• Optimize driver behavior for low power, latency, and performance.
• Analyze power traces, wakeup statistics, kernel traces, and subsystem state transitions to improve energy efficiency.
• Ensure drivers follow proper sequencing for active, idle, suspend, resume, shutdown, and error-recovery states.

Android/Linux Integration

• Integrate kernel drivers with Android/Linux userspace interfaces where applicable.
• Work with sysfs, debugfs, procfs, character devices, input subsystem, power supply interfaces, thermal zones, and HAL-facing kernel interface…
