Sony Interactive Entertainment isn’t just the Best Place to Play — it’s also the Best Place to Work. We’re the company behind Play Station, delivering cutting‑edge hardware, software, and network services to players and game creators around the world. Our role is to create the technologies, tools, and experiences that help developers build the best games on Play Station. We work at the intersection of platform engineering, developer experience, and interactive entertainment, pushing the boundaries of play through high‑quality SDKs, systems, and tools.

We are looking for a Senior Software Engineer, Audio Quality Engineering to design, build, and own tools, systems, and automated analysis pipelines that help ensure the quality, correctness, and reliability of audio technologies within the Play Station SDK. In this role, you will work closely within the QE team and with the Audio SDK team and other platform engineering groups to develop software that validates audio output, detects regressions, measures quality, and provides actionable feedback to engineers.

You will help define how we evaluate audio behaviour across libraries, platforms, and SDK releases, building robust developer‑facing and internal tools that improve confidence in Play Station audio technologies. The ideal candidate combines strong software engineering skills in C/C++ and Python with a practical understanding of digital audio, signal analysis, test automation, and SDK quality. You should be comfortable working independently, making technical trade‑offs, collaborating across teams, and turning ambiguous quality problems into reliable engineering systems.

Based in London, our team is part of the Foundational Systems and Experiences Engineering group. We build and test low‑level SDKs and fundamental technologies used by game development partners to create Play Station games. You will work with engineers developing Play Station audio technologies, including SDK libraries, tools, runtime systems, and platform‑level audio features. The role sits close to both engineering and quality, with a focus on building the technical foundations that allow us to measure, validate, and continuously improve audio quality across the Play Station SDK.

• Design, develop, and maintain audio quality tools, automated analysis systems, and test infrastructure for Play Station SDK audio libraries and technologies.
• Write high‑quality C/C++ and Python code to analyse audio output, detect regressions, compare behaviour across SDK versions, and validate correctness against expected results.
• Build systems that support repeatable audio quality measurement, including signal analysis, spectral comparison, perceptual metrics, conformance checks, and regression detection.
• Own audio quality engineering features end to end, from requirements and design through implementation, CI integration, documentation, maintenance, and long‑term support.
• Work closely with Audio SDK engineers to understand new features, define testability requirements, and ensure quality is considered early in design and implementation.
• Develop tooling that gives engineers clear, actionable insight into audio defects, quality trends, and behavioural changes.
• Support SDK release quality by improving automated validation, build/test pipelines, reporting, dashboards, and failure investigation…
