Senior Audio Software Development Engineer ( 2-10 years experience )

VOCAL is in search of an audio engineer who is highly capable in implementing algorithms within the voice technology domain including acoustic beamforming, adaptive filtering, noise reduction and speech coding. Engineer will be joining team responsible for designing, developing, coding and testing acoustic and voice solutions through productization. The ideal candidate has industry experience achieving real-time embedded fixed point solutions ported from high level algorithms validated in Matlab or similar. Role has high level of impact and contribution.

Competitive candidates will

• Understand phased array system design and optimization for broadband signals.
• Understand trade-offs in RTOS algorithm design for power consumption, algorithm complexity and WNG.
• Understand the design of microphone array configurations such as ULA and UCA.
• Understand the theory of DOA estimation using various algorithms such as MUSIC, ROOT-MUSIC, ESPRIT, GCC-PHAT, SRP-PHAT etc. and their limitations for applications to acoustic signals.

Responsibilities of the Acoustic Beamforming Engineer include

• Designing fast and efficient acoustic DSP algorithms for implementation on embedded processors.
• Analyze the performance impact of algorithms by estimating the processing resources such as MIPS, ROM and RAM.
• Coordinate software development activities with other DSP engineers such as prototyping and tuning algorithms to meet and exceed customer requirements
• Testing performance of algorithms such as beamforming, AEC, ANR, dereverberation, VAD, and BSS by using both subjective and objective measures, and with speech recognition engines.
• Research on new technologies and how they can be incorporated in VOCALs custom products for improvement.
