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.

• 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 workflows.
• Investigate complex audio issues using a combination of debugging, data analysis, signal processing, and collaboration with domain experts.
• Help define engineering standards for audio quality tooling, including maintainability, reproducibility, performance, scalability, and documentation.
• Collaborate with platform, tools, test, release, and globally distributed engineering teams to improve audio quality processes across the SDK.
• Mentor other engineers, share technical knowledge, and contribute to a culture of high‑quality, testable, maintainable software.

• Strong professional experience in software engineering, ideally with ownership of tools, systems, SDK components, test infrastructure, or quality‑focused engineering projects.
• Excellent C/C++ and Python programming skills.
• Practical knowledge of digital audio fundamentals, such as PCM audio, sample rates, channels, latency, dynamic range, frequency‑domain analysis, filtering, resampling, encoding, or spatial audio concepts.
• Experience designing, implementing, and maintaining automated test systems, analysis tools, or quality pipelines.
• Ability to analyse complex technical problems, evaluate trade‑offs, and deliver robust, maintainable solutions with minimal supervision.
• Strong debugging and problem‑solving skills, including the ability to investigate failures across software, tooling, data, and environment boundaries.
• Experience setting up CI/CD systems, source control, code review, and modern collaborative development workflows.
• Ability to write clear technical documentation and communicate complex topics to both audio specialists and non‑audio stakeholders.
