Qualcomm is a pioneer in silicon and software technologies for consumer electronics and a global leader in wireless innovation. We are looking for Audio DSP / Embedded Software Engineers based in Bangalore to work on next-generation voice and music solutions. 

The role involves designing, developing, porting, integrating, and optimizing audio codecs on ARM and HiFi DSP platforms. You will work as part of the DSP team on codec libraries, DSP frameworks, and system-level audio pipelines, integrating audio algorithms into production platforms and enabling end-to-end audio use cases. 

The position requires strong hands-on experience with embedded C/C++ development, fixed‑point arithmetic, and performance‑critical code optimization, focusing on MCPS, code size, heap/memory usage, latency, and power consumption. You will profile and debug issues on real hardware platforms and collaborate closely with platform, interface, and customer teams to deliver robust, customer-ready audio solutions. 

Key responsibilities include developing high-quality embedded DSP software for voice and music products; troubleshooting and resolving complex issues; supporting customer requirements; contributing to project planning and execution; creating and maintaining engineering documentation; and contributing to Qualcomm’s intellectual property, including support for patent submissions. 

• 2+ years of relevant industry experience in embedded/DSP audio development 

• Experience in audio codec development and integration (e.g., AAC, LC3, SBC, CVSD) 

• Hands-on experience working on ARM and HiFi DSP (or equivalent DSP platforms) 

• Proficiency in C/C++ for embedded systems, including HiFi and/or ARM architectures. 

• Strong foundation in audio signal processing and codec fundamentals. 

(MDCT, quantization, psychoacoustics, bitstream structures) 

• Hands-on experience with fixed-point arithmetic and performance‑critical embedded code. 

• Experience in optimizing code for: 

• Execution speed (MCPS) 

• Code size 

• Heap and stack memory usage 

• Latency and power consumption 

• Experience integrating codecs into audio pipelines and system-level audio frameworks 

• Strong debugging, problem-solving, and analytical skills 

• Experience profiling and debugging audio behaviour on real hardware platforms 

• Ability to work independently and collaboratively in cross‑functional teams 

• Effective verbal and written communication skills 

• Engineering degree in Electronics, Electrical Engineering, Computer Science, or related field 

• Experience with HiFi DSP, ARM DSP extensions, or equivalent DSP architectures 

• Familiarity with embedded audio frameworks, DSP frameworks, and OS-level audio stacks 

• Exposure to customer support, platform enablement, or ecosystem integration 

• Familiarity with digital audio interfaces and formats (PCM, I2S, SPDIF) 

• Knowledge of RTOS concepts such as tasks, queues, semaphores, and scheduling 

• Experience with tools and scripting languages such as Python, MATLAB, and Makefiles 

• Prior experience working on Qualcomm/CSR platforms is a plus 

• Experience working with multi-site or cross-geo teams
