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.

We offer multiple benefits that include

• The environment of equal opportunities, transparent and value-based corporate culture, and an individual approach to each team member

• Competitive compensation and perks. Annual performance review

• Gig-contract

• 21 paid vacation days per year, paid public holidays according to Ukrainian legislation
