We are seeking a Principal Audio Software Engineer to join our team, leading the development of advanced audio processing technologies for our next generation of handheld mobile radio products. This role is critical to ensuring exceptional voice intelligibility, robustness, and reliability in the demanding environments faced by critical communications users.
Working collaboratively with embedded software, hardware, systems engineering, and other audio specialists, the successful candidate will be responsible for architecting, developing, and optimising real-time audio algorithms and software. This includes driving innovations in noise reduction, echo cancellation, beamforming, audio enhancement, and other DSP technologies essential for delivering best-in-class communication performance.
You will play a pivotal role in shaping lifesaving and mission-critical communication tools, where audio clarity and system reliability are paramount. We offer a challenging yet rewarding environment where your software and audio expertise will directly influence the performance and dependability of essential products.
Key Responsibilities- Audio Software Design & Development: Architect, design and implement real-time audio processing algorithms and DSP pipelines. Develop technologies such as noise reduction, acoustic echo cancellation (AEC), beamforming, voice activity detection, advanced audio enhancement, and custom codecs. Ensure software solutions meet stringent performance, latency, stability, and reliability requirements for mission-critical communications.
- Technical Leadership: Serve as the technical authority for audio software, guiding design decisions and setting engineering standards. Lead technical reviews, mentor junior engineers, and support cross-functional engineering teams. Drive architectural evolution of audio subsystems and long-term technology roadmaps.
- Collaboration & Integration: Work closely with embedded software, hardware, systems engineering and acoustics teams to ensure seamless integration of audio technologies. Support product development from concept through to delivery, including prototyping, testing, tuning, and verification. Collaborate with product management to define requirements and translate them into robust technical solutions.
- Quality, Testing & Optimisation: Conduct performance analysis, debugging, and optimisation of audio software across multiple platforms. Develop automated test frameworks and audio validation tools where appropriate. Ensure compliance with relevant communication, safety, and industry standards.
- Research & Innovation: Stay informed of emerging audio technologies, DSP methods, and industry trends. Explore new algorithmic approaches and evaluate third-party solutions when suitable. Contribute to patents, white papers, and internal technical knowledge bases.
Our customer base includes many different industries and markets around the world. Our complete TETRA and LTE solutions have been developed specifically for users in multiple sectors to face their critical communications challenges. There is no such thing as a typical day here at Sepura. You will be supported by your manager and team, as well as collaborating with other departments across the business. The Audio Team at Sepura follows an Agile development process centred around the heartbeat of Scrum ceremonies. During each sprint you could be taking on several tasks related to several of the responsibilities listed above. This role will require security clearance.
What You Need To Succeed- Required Skills and Experience: Education: Bachelor’s or Master’s degree in Electrical Engineering, Computer Science, Audio Engineering, DSP, or a related field. Experience: 5+ years of professional experience developing real-time audio software, DSP algorithms, or embedded audio systems. Technical Proficiency: Deep knowledge of DSP algorithms (AEC, NR, AGC, beamforming, VAD, filtering). Strong coding skills in C/C++ for real-time embedded systems. Experience optimising for low-latency and resource-constrained platforms. Familiarity with audio frameworks, DSP libraries, or fixed-point environments. Strong analytical, problem-solving and debugging skills. Ability to lead complex technical projects end-to-end.
- Preferred (Nice-to-Have): Experience in mission-critical or safety-critical communication systems. Knowledge of TETRA, DMR, LTE/MCX or similar communication standards. Experience with MATLAB or Python for algorithm development and validation. Understanding of beamforming, microphone arrays, or acoustic system behaviour. Experience with ARM platforms, RTOS environments, or multi-core optimisation. Exposure to ML-based audio processing techniques.
