DSP-SDK Lead

Key Responsibilities :

DSP SDK Development

• Develop, maintain, and optimize DSP SDK components, including:

• Hexagon runtime libraries

• DSP-side APIs and frameworks

• RPC/IPC communication layers

• Drivers and services for DSP subsystems (ADSP, CDSP, SLPI)

• Build and enhance DSP development tools (debug, profiling, loading, tracing).

• Support on-target debugging, simulation environments, and performance analysis tools.

Subsystem Integration & Validation

• Work closely with Firmware, Audio, Camera, Sensors, AI, and Modem teams to integrate SDK modules.

• Validate SDK functionality on:

• QDSP6-based DSPs

• Android/Linux platforms

• Bare-metal and RTOS setups

• Debug low-level issues related to:

• DSP boot

• RPC failures

• Memory configuration

• DSP <-> Apps communication

• Performance bottlenecks

Optimization & Performance

• Optimize DSP libraries for:

• Throughput and latency

• Memory footprint

• Power efficiency

• Multi-threaded/parallel execution

• Use profiling tools (QDSS, QPST, trace tools) to tune DSP performance.

Developer Support & Documentation

• Provide guidance to internal teams on using DSP SDK features.

• Develop technical documentation, sample code, and best practices for OEMs and internal partners.

• Work closely with tools and compiler teams to improve development workflows.

Required Skills

• Strong understanding of:

• DSP architecture (preferably Qualcomm Hexagon/QDSP6)

• Embedded systems concepts (RTOS, memory, IPC, boot flows)

• Multi-core and heterogeneous compute frameworks

• Experience in:

• C/C++ programming

• DSP programming/optimization

• Linux/Android development environments

• IPC frameworks (RPC, FastRPC, QMI)

• Proficiency with debugging tools such as:

• QXDM, QDSS, JTAG

• Profiling and trace utilities

• Log analysis tools

Good to Have Experience with:

• Hexagon SDK or equivalent DSP SDKs

• FastDSP, FastRPC, and Qualcomm subsystem frameworks

• Low-power design or Always-On DSP pipelines

• Multimedia pipelines (Audio, Imaging, AR/VR)

• AI/ML acceleration on DSP

• Exposure to:

• Firmware development

• Build systems (Scons, CMake, Android build)

• Python for automation

Soft Skills:

• Excellent communication and cross-functional collaboration.

• Leadership in technical decision-making.

• Ability to translate complex hardware/software constraints into practical solutions.

• Mentorship and technical coaching for junior engineers.
