If you're a Principal Audio Software Engineer and are based in or around Cambridge, we would love to hear from you!

This particular position sits at the forefront of real-time embedded audio innovation, focused on delivering exceptional performance in demanding operational environments where reliability is essential.

Location: Cambridge (Fully on site)

Job Type: Full-time, Permanent

Salary: £60,000 to £75,000

The Role

As a Principal Audio Engineer, you will take ownership of the architecture, design, and optimisation of real-time audio software and DSP pipelines powering handheld communication products.

Working closely with embedded software, hardware, systems engineering, and acoustics specialists, you will guide technical direction while remaining hands-on in algorithm development and system optimisation.

What You’ll Be Doing:

• Architecting and implementing real-time audio processing algorithms.
• Developing technologies including noise reduction, acoustic echo cancellation, beamforming, voice activity detection, and audio enhancement.
• Ensuring software meets strict latency, stability, and performance requirements.
• Acting as the technical authority for audio software design decisions and engineering standards.
• Leading technical reviews and mentoring engineers within the wider team.
• Driving the evolution of audio subsystems and future technology roadmaps.
• Supporting product development from early prototyping through validation and release.
• Performing performance analysis, debugging, and optimisation across multiple platforms.
• Developing automated validation approaches for audio performance testing.
• Researching emerging DSP techniques and contributing to innovation initiatives.

Essential Skills & Experience:

• Degree (Bachelor’s or Master’s) in Electrical Engineering, Computer Science, Audio Engineering, DSP, or related discipline.
• Significant commercial experience developing real-time audio or DSP software.
• Deep understanding of DSP algorithms including AEC, noise reduction, AGC, filtering, and beamforming.
• Strong programming capability in C/C++ for embedded or real-time systems.
• Experience optimising software for low-latency, resource-constrained platforms.

Desirable Experience:

• Experience within mission-critical or safety-critical communication systems.
• Knowledge of communication standards such as TETRA, DMR, LTE, or MCX.
• Algorithm development using MATLAB or Python.
• Experience with microphone arrays or acoustic system behaviour.
• Exposure to ARM platforms, RTOS environments, or multi-core optimisation.

Who You Are:

• A technically authoritative engineer who enjoys solving complex signal-processing challenges.
• Comfortable influencing architectural direction while remaining hands-on.
• Collaborative when working across multidisciplinary engineering teams.
• Analytical and detail-oriented, with a focus on performance and reliability.
