🔍 DSP / Audio Signal Processing Engineer

Location: 100% remote
Contract type: B2B
Capacity: Full-time

🚀 About the project

We are looking for an experienced DSP / Audio Signal Processing Engineer to support the development and improvement of advanced digital audio solutions.

The project involves implementing, integrating, and testing signal processing algorithms used in modern audio systems. You will work with existing DSP architectures, analyze signal flows, and contribute to improving audio processing performance and quality.

We are looking for someone who combines strong DSP fundamentals with hands-on C/C++ development experience and can quickly understand existing solutions and contribute to technical tasks.

Experience with commercial audio products is highly valued, but we are also open to engineers with a strong DSP background from other industries.

💡 Who we are

Kyotu Technology is a boutique software house based in Wrocław and Warsaw, working fully remotely or in hybrid mode across Poland. We focus on long-term, high-quality engineering and building complex, production-grade systems with real business impact. Our teams have real influence on technical and architectural decisions.

🧠 Your responsibilities

develop, implement, and optimize Digital Signal Processing algorithms using C/C++
work with existing audio processing architectures and signal flow diagrams
integrate and modify DSP components within audio processing pipelines
implement and improve algorithms related to filtering, equalization, gain control, and other audio processing functions
analyze interactions between different DSP algorithms and processing stages
test, debug, and validate signal processing implementations
investigate audio quality, performance, and system behavior issues
collaborate with engineering teams on technical improvements and implementation decisions
support troubleshooting and verification of audio processing solutions

🧩 Must haves

strong theoretical and practical knowledge of Digital Signal Processing (DSP)
solid commercial experience implementing DSP algorithms in C/C++
good understanding of digital signal representation, sampling, filtering, and signal processing fundamentals
experience with digital filter design and implementation
understanding of floating-point and fixed-point arithmetic in DSP applications
practical experience with at least some of the following algorithms:
- Digital Filtering and Equalization
- Automatic Gain Control (AGC)
- Noise Reduction / Noise Suppression
- Acoustic Echo Cancellation (AEC)
- Adaptive Filtering
- Beamforming
- Voice Activity Detection (VAD)
- Audio Mixing and Gain Processing
ability to understand and interpret DSP block diagrams, signal flow architectures, and processing chains
experience integrating, modifying, or debugging signal processing components
ability to translate DSP concepts and mathematical models into working software implementations
experience testing and troubleshooting DSP-based systems
strong analytical and problem-solving skills
ability to work independently and quickly understand existing technical solutions
good English communication skills

✨ Nice to have

experience developing commercial audio products, such as headphones, headsets, speakers, or communication devices
knowledge of psychoacoustics and perceptual audio processing
experience with advanced adaptive audio processing algorithms
experience with Machine Learning or Neural Networks applied to signal processing
background in embedded audio systems
experience in telecommunications, radar, or other DSP-intensive industries
