Job Summary
We're looking for a skilled Audio Signal Processing Engineer to join the team at SQUAD. You will be responsible for a critical project focused on a core functionality within our customers’ products. This includes replacing a key audio processing component with a new, more suitable alternative. Your role will involve managing the entire process, from initial research and analysis to final implementation and testing, with a focus on delivering a high-quality, seamless transition. Your work will involve integrating digital signal processing algorithms within complex, multi-threaded architectures.

Responsibilities and Duties

– Analyze and characterize the behavior and performance of an existing audio component to create a baseline for comparison
– Research alternative open-source and commercially licensed libraries and propose an optimal solution to the team
– Develop a custom implementation from scratch if no suitable alternative is found
– Integrate DSP algorithms and control structures into our audio frameworks and multi-core architectures
– Conduct extensive regression and integration tests to ensure zero regressions in audio quality or functionality
– Own the quality of your code, with a commitment to a test-driven approach
– Cooperate with other engineering teams to select optimal hardware and software solutions, ensuring total system performance
– Present your findings and proposals in a formal document, demonstrating strong technical writing skills.

Qualifications and Skills

– Bachelor's or Master's degree in Electrical Engineering, Computer Science, or a related technical field
– 5+ years of hands-on experience developing robust embedded software
– Proven expertise in C/C++ for developing high-performance, real-time systems
– Deep expertise in Digital Signal Processing (DSP) with a strong background in audio
– Extensive experience with acoustic and speech processing algorithms, including noise control, filtering, and echo cancellation
– A solid understanding of DSP frameworks and how to integrate algorithms into control software
– Experience in tuning and calibrating complex systems of algorithms
– A solid understanding of wireless communication protocols (e.g., Bluetooth, Wi-Fi)
– At least an Upper-Intermediate level in both written and spoken English (B2).

Nice to have

 – Experience with multi-core System-on-Chip (SoC) processors
– Familiarity with common digital communication protocols, such as I2C, I2S, SPI, UART, and USB
– A deep understanding of acoustic principles and audio systems design
– Practical experience with Linux audio frameworks, including PulseAudio and audio plugin APIs.
