Position Summary

Mirafra Technologies is actively seeking an experienced, high-caliber, and technical Audio DSP Developer with 2.5 to 6 years of progressive professional experience in digital signal processing, audio algorithm implementation, and embedded firmware development to join our client engineering team on a full-time permanent on-site basis in Bangalore, India. In this critical audio engineering and signal processing role, you will be responsible for designing, developing, optimizing, and integrating advanced audio algorithms, codecs, and signal processing pipelines on dedicated digital signal processors (DSPs) and embedded microcontrollers. You will leverage your deep specialist expertise in C/C++, assembly programming, DSP architecture, and audio psychoacoustics to deliver uncompromised sound quality, low latency, and operational excellence. This opportunity offers competitive compensation, executive technical visibility, and exceptional career growth prospects within a premier global semiconductor and embedded engineering enterprise.

Detailed Job Description

As an Audio DSP Developer supporting Mirafra Technologies in Bangalore, India, you will take full operational, tactical, and technical ownership of audio signal processing pipeline design, algorithm optimization, codec implementation, and real-time performance tuning across mission-critical consumer electronics and automotive audio platforms. Your day-to-day responsibilities include designing, writing, testing, and optimizing high-performance C, C++, and assembly code for fixed-point and floating-point DSP processors (Tensilica HiFi, Qualcomm, ARM Cortex-M/A, Analog Devices SHARC), implementing and tuning advanced audio algorithms including acoustic echo cancellation (AEC), noise suppression (ANS), active noise cancellation (ANC), beamforming, equalization, and spatial audio, configuring and managing audio interfaces (I2S, TDM, SoundWire) and DMA data transfer streams, collaborating closely with cross-functional hardware engineering, acoustic engineering, and QA squads in Agile sprint cycles, conducting rigorous audio quality evaluation, latency profiling, memory footprint reduction, and root cause analysis (RCA) to resolve complex signal processing anomalies, preparing comprehensive technical documentation of algorithm specifications, architecture diagrams, and operational runbooks.

Key Responsibilities

• Design, develop, optimize, test, and maintain advanced audio digital signal processing (DSP) algorithms and software pipelines.
• Implement and tune real-time audio features including Acoustic Echo Cancellation (AEC), Noise Suppression (ANS), ANC, and beamforming.
• Port, optimize, and profile audio codecs and filtering algorithms on fixed-point and floating-point DSP processors (Tensilica, ARM).
• Author high-performance C, C++, and assembly code optimized for cycle count, instruction cache, and memory utilization.
• Configure and manage digital audio interfaces (I2S, TDM, SoundWire) and low-latency DMA buffer management.
• Execute systematic audio bench testing, subjective listening tests, objective metric evaluation (THD+N, SNR), and latency profiling.
• Collaborate seamlessly with cross-functional acoustic engineering, hardware design, and software validation squads.
• Maintain accurate, comprehensive technical documentation of algorithm architectures, tuning parameters, and operational runbooks.

Required Qualifications & Skills

• Bachelor’s degree in Electronics and Communication Engineering, Computer Science, Electrical Engineering, or a related discipline.
• Minimum of 2.5 to 6 years of progressive professional experience in digital signal processing, audio software engineering, and DSP development.
• Strong, demonstrable hands-on professional expertise in advanced C and C++ programming and assembly optimization for DSP architectures.
