Job Description
Hi
Please find the below JD
Key Responsibilities:
1. Power Management Software Development
- Develop and optimize platform-specific power management features on SoCs (based on custom Oryon CPUs).
- Implement DVFS (Dynamic Voltage and Frequency Scaling), Sleep/Wake logic, and rail/clock gating across CPU, NPU, GPU, and DSP domains.
- Integrate with Power Management ICs (PMICs) and configure resource power managers (RPMh, RSC).
2. Low Power Mode Enablement:
- Enable platform deep sleep, suspend-to-idle, and system sleep states tailored for Always-On (AON) use cases.
- Validate retention/restore sequences of SoC subsystems and memory during low-power modes.
- Integrate SPMI-based communication with PMIC for power domain control.
3. Thermal & Performance Scaling:
- Develop and tune thermal mitigation policies using sensors and thermal zones.
- Interface with Battery Management System (BMS) and configure thermal trip points.
- Implement CPUFreq/DevFreq drivers with QoS-aware thermal throttling and performance caps.
4. Power & Thermal Characterization:
- Measure and optimize platform power (active and idle) using Trepn Profiler, QDART, QPST, and onboard fuel gauges.
- Perform power regression analysis across software releases and feature integrations.
- Work with system architects to define performance-per-watt KPIs for devices (e.g., AI laptops, edge compute systems).
5. Firmware and Bootloader Integration:
- Collaborate with UEFI/TF-A developers to manage early-stage power initialization.
- Coordinate with XBL, ABL, and UEFI teams for seamless handoff of power states to Linux/Windows OS.
6. Debug & Bring-up Support:
- Triage system-level power and thermal issues with tools like QXDM, QPST, kernel logs, ftrace, trace32, JTAG.
- Work with silicon validation teams to debug board-level or SoC-level anomalies in power delivery or heat dissipation.
7. Cross-Team Collaboration:
- Partner with PMIC, platform, kernel, BSP, and thermal teams to co-design efficient power solutions.
- Support OEM/ODM partners in tuning and validating power features for commercial products (e.g., laptops or tablets).
- Contribute to system-level test plans and validations for power and thermal readiness at EVT/DVT stages.
Required Expertise:
1. Qualcomm-Specific Knowledge:
- Hands-on experience with Resource Power Manager (RPMh), SPMI, TSENS, and CPR (Core Power Reduction) mechanisms.
- Familiarity with Oryon CPUs, Hexagon DSPs, Adreno GPU, and AI accelerators.
- Experience with tools: QXDM, QPST, Trepn Profiler, QDART, Dragonboard/CRB environments.
2. OS and Driver Development:
- Strong C/C++ development skills for Linux or Windows kernel power/thermal subsystems.
- Integration of custom PMIC or thermal drivers in AOSP or Yocto-based distributions.
3. Power Profiling & Tuning:
- Use of Trepn, PowerTOP, ftrace, perf, and RAPL-like interfaces for detailed power/perf analysis.
- Tuning performance-per-watt metrics across workloads (AI inference, GPU rendering, video playback, etc.).
4. Debugging and Analysis:
- Strong log analysis skills (kernel, ADB, QXDM).
- Familiarity with JTAG/debug probes, boot tracing, and event timelines for power issue debugging.
Preferred Qualifications:
- Prior experience working on any platforms (reference or commercial).
- Familiarity with Linux on ARM64 and power management on ARM64 SoCs.
- Knowledge of modern thermal management techniques for fanless laptops or ultrabooks.
- Exposure to AI performance-power optimization, e.g., NPU power scaling for LLM workloads
