Job Description

We seek an enthusiastic senior hands-on Performance Profiling Engineer. This is a Full-Time Permanent position and requires to work on-site Monday through Friday (no remote work).

In this role, you will do the following: Performance profiling of use cases and key algorithms on the targeted platform:

• Port software builds to the new target hardware platform.
• Bring up rapid prototyping and demo the feature on the target platform.
• Create and analyze the profiling traces to benchmark the key system events/sessions.
• Map out the system/hardware settings to analyze and find out the key performance bottlenecks and system/events dependency and recommended solutions.
• Performance tuning by adjusting system settings (HW/SW setting, scheduling, priorities, etc.), removing unnecessary dependency, etc.
• Benchmark and optimize key algorithms' performance.
• Automate profiling scripts and create a dashboard to track changes easily.
• Test plans, setup, procedures, build instructions.
• Use case/key algorithms’ performance profiling reports
• Prototype demos
• Performance bottleneck analysis, recommended solutions, and optimization reports
• Automated profiling scripts
• Regression reports

REQUIREMENTS:

• 10+ years’ experience in mobile performance profiling.
• Proficient in Python and shell scripts
• Expert in profiling tools such as Perfetto, ftrace, ATrace, etc.
• Strong understanding of mobile SoC and hardware/software interactions.
• Strong understanding of cache hierarchy, memory bandwidth, connectivity, and the tradeoff between perf and power.
• Strong programming and debugging skills with Linux Kernel.
• Expertise in Android/WearOS boot flow and BSP (Board support package) is a must.
• In-depth understanding of different DSP architectures, such as HiFi2/3/5.
• Hands-on experience optimizing algorithms on DSP architecture, DSP Code Optimization, and performance measurement.
• Familiar with real-time operating systems, such as uCOS and FreeRTOS, including their threading, scheduler, synchronization, and resource management.
• Familiarity with ISP, GPU architecture, and Vulkan programming API is a plus.
• Knowledge of mobile systems' performance/power workloads, such as CPU/GPU benchmarks, speech translation, navigation, voice assistant, notification, photo, video recording, and binocular video playback, is a plus.
• Knowledge of AR/VR eye/hand tracking and 6D
