Audio Plugin Engineer

Marshall Group is the audio, tech, and design powerhouse uniting musicians and music lovers through genre‑breaking innovation. Our flagship brand, Marshall, is uniquely positioned with over 60 years of rock 'n' roll attitude on stage, at home, and on the go. Our iconic products are brought to life by a dedicated team of 800 passionate employees and sold in over 90 markets worldwide.

Right now, we need to strengthen our R&D team in Milton Keynes with an Audio Plugin Engineer who will help design, build, and release the desktop applications and audio plugins behind Marshall’s digital amp products. You will work on software used directly by musicians, from audio plugins to standalone tools that shape how Marshall hardware is experienced. This is the right role if you want to go deep technically, own real products end to end, and work closely with a small, highly skilled engineering team.

You will build and maintain cross‑platform desktop applications and professional audio plugins using JUCE and modern C++. Working closely with another specialist engineer, you will integrate DSP code, develop user‑friendly front ends, and help bring products to public. You will contribute across the full lifecycle, from early technical decisions to release readiness, while collaborating with embedded and hardware teams to ensure seamless hardware–software integration.

• Develop and maintain cross‑platform C++ code for audio processing used across multiple products
• Deliver standalone and VST, AAX, and AU audio plugins for Marshall digital amp products
• Integrate existing and new DSP code into production‑ready applications
• Build internal tools that support embedded firmware development
• Support CI build systems, testing practices, and release processes
• Contribute to the specification and design of consumer‑facing software products

You are a hands‑on engineer who enjoys working in small teams where ownership, initiative, and collaboration matter. You are comfortable operating under delivery pressure and getting up to speed quickly on existing codebases. You want to grow as a technical specialist, and you are motivated by building high‑quality tools and products for musicians and audio enthusiasts.

• A couple of years professional experience working with JUCE and modern C++
• Proven understanding of computer science and audio technology through professional work or education
• Experience using Git in a professional software development environment
• Professional experience building audio plugins for formats such as VST3 is a strong advantage
• Proven experience implementing PACE iLok, notably Fusion, is a strong advantage

We strive to foster an inclusive workplace and we do not discriminate on the basis of race, religion, disability, colour, national origin, gender, sexual orientation, age or marital status. We firmly believe that Marshall thrives when our employees do, leading to better experiences for our consumers.
