Software Engineer - Audio Systems

This is a rare opportunity to join a well-backed, early-stage tech company building something genuinely new in the audio space. With an experienced founding team and a greenfield roadmap, you’ll play a defining role in shaping a product from day one.

Role Overview:

• Location: London (4 days per week in-office)
• Package: Competitive salary + equity + healthcare
• Industry: Audio Technology / Embedded Systems / Applied ML

What You’ll Be Doing:

• Owning the end-to-end audio subsystem for a compact, low-power edge device and its supporting cloud pipeline
• Designing and optimising real-time audio capture, on-device DSP, and cloud-based post-processing
• Implementing and fine-tuning DSP components such as filtering, AGC/DRC, noise suppression, VAD, and echo control
• Building robust audio pipelines that perform reliably in noisy, unpredictable environments
• Balancing latency, compute, power, and audio quality to achieve production-ready performance
• Defining objective metrics and creating repeatable evaluation and regression testing frameworks (lab and field)
• Debugging issues across embedded, hardware, and cloud layers using profiling, logging, and lab instrumentation
• Collaborating closely with hardware, embedded, and ML engineers to integrate intelligent audio features
• Contributing to engineering best practices, documentation, and technical design discussions

Main Skills Needed:

• Proven experience delivering embedded audio systems (or significant audio subsystems) into production
• Strong fundamentals in DSP and hands-on tuning experience (e.g. AGC/DRC, filtering, noise suppression; AEC/beamforming advantageous)
• Strong C/C++ skills with confidence working under real-time and resource constraints
• Experience using Python (or similar) for analysis, benchmarking, and evaluation tooling
• Practical understanding of audio codecs and streaming/recording pipelines
• Ability to operate effectively in a fast-paced startup environment with high ownership
• Strong communication skills and confidence working cross-functionally

Bonus if you have:

• Hardware-adjacent experience (I2S, ADC/DAC, DMA, SPI/I2C/UART, lab debugging tools)
• Microphone/speaker component selection or acoustic/mechanical insight
• Experience designing structured audio measurement methodologies
• Exposure to low-power / always-on detection or audio classification systems
• Familiarity with ML frameworks and deploying models into production pipelines
• Experience with established audio libraries or frameworks

What’s in It for You:

• A genuine greenfield opportunity to shape a product roadmap from the very beginning
• High ownership and autonomy within a small, experienced, low-ego team
• Direct impact on a product designed to disrupt its market
• Collaboration across embedded, hardware, cloud, and ML disciplines
• Modern tooling and fast iteration cycles to keep you focused on building
• Competitive salary, meaningful equity, and healthcare
• A collaborative, in-person culture designed to accelerate learning and decision-making
