Responsibilities
Design and implement DSP algorithms across multiple chip architectures (ARM, VLIW, SIMD/vector DSPs, and proprietary accelerators)
Work in tight collaboration with the Algorithm team to refine algorithm definitions, validate numerical behavior, and support floating-point to fixed-point transitions
Develop and optimize performance-critical kernels using chip-specific intrinsics, vector operations, and low-level optimization techniques
Analyze compiler output and optimize generated code through assembly review, compiler reports, and profiling-driven tuning
Build complete DSP processing pipelines and applications in multi-processor / multi-core environments for real-time embedded systems
Optimize system-level performance including compute scheduling, memory/bandwidth usage, latency budgets, and real-time constraints
Debug and root-cause issues related to performance, numerical stability, and real-time correctness across hardware and software boundaries
Collaborate cross-functionally with Algorithm, Architecture, Silicon, Verification, and Embedded SW teams to ensure correct integration and best system-level performance
Qualification
Required
Bachelor's degree in Computer Science, Electrical Engineering, or a related field
At least 5 years of hands-on experience implementing DSP algorithms in production systems
Proven experience implementing and optimizing DSP software on architectures such as VLIW and SIMD/vector processors (and/or ARM-based platforms), including performance-critical kernel development
Experience with low-level performance optimization techniques, including use of chip-specific intrinsics and analysis of compiler-generated assembly code
Experience developing real-time embedded software in multi-core / multi-processor environments
Experience working with MATLAB and Python for algorithm development, modeling, validation, or prototyping
Preferred
Experience with specific DSP platforms and toolchains (e.g., Xtensa, Hexagon, CEVA, or proprietary VLIW/vector DSP processors)
Experience implementing high-rate signal processing pipelines for sensor or perception systems (radar, lidar, camera, audio, or similar)
Strong familiarity with RTOS environments, real-time scheduling, and synchronization primitives
Understanding of SoC-level integration topics such as memory hierarchy, DMA engines, cache behavior, and accelerator interfaces
Experience building automated testing, CI/regression frameworks, and performance regression tracking for embedded DSP software
