JOB OVERVIEW

________________________________________________________________________________

We are seeking a Senior System Software Engineer with strong expertise in Android power management to do “System‑level power characterization using Qualcomm internal measurement platforms.”

. This role focuses on power measurement setup, characterization, and optimization across Android system software, spanning firmware, kernel, framework, and thermal management layers.

You will work hands‑on with power measurement equipment, analyze and optimize peak power, battery usage, and thermal behavior, and collaborate closely with hardware, firmware, and platform teams to improve system‑level power efficiency.

This is a senior, hands‑on engineering role, ideal for engineers who thrive at the intersection of Android internals, embedded firmware, and hardware power systems

Responsibilities:

• Android Power & Thermal Engineering
  • Design and execute power measurement setups using lab equipment (bench supplies, power analyzers, oscilloscopes).
  • Profile and optimize Android power consumption across idle, steady state, and peak usage scenarios.
  • Analyze and tune Android Power, Battery, and Thermal frameworks, including:
    • Power Manager & wake locks
    • Thermal HAL & thermal policies
    • CPU/GPU frequency scaling and governors
    • Suspend / resume behavior
    • active idle and sleep mode behavior.
  • Identify and mitigate excessive power draw, thermal throttling, and performance bottlenecks.
• System Software & Firmware Development
  • Debug and enhance power‑related behavior across:
    • Android Framework & system services
    • HAL layers (Power / Thermal / Sensor related)
    • Linux kernel and device drivers
    • Android Power management , expertise in cpu governors etc.
  • Work closely with embedded firmware teams (MCU / peripheral firmware) to coordinate system‑level power strategies.
  • Support bring‑up and optimization of new Qualcomm platforms.
• Measurement, Analysis & Automation
  • Correlate electrical power measurements with system‑level logs and traces.
  • Use Android and Linux tools (ADB, dumpsys, systrace, logs, kernel traces) for root‑cause analysis.
  • Create scripts or tools to automate power characterization and regression testing.

• Cross‑Functional Collaboration
  • Partner with hardware, silicon, and platform teams to align power architecture and software behavior.
  • Provide guidance on design‑for‑power and design‑for‑thermal best practices.
  • Support customers and internal teams with power and thermal investigations.

Basic qualifications
