We're looking for a Senior Software Engineer to build the tools and automated systems we use to validate audio technologies in the PlayStation SDK. This role sits within SDK Quality Engineering, but the work is primarily software engineering. You'll design and build audio analysis tools, automated validation pipelines, regression detection systems, and developer facing diagnostics that help engineers understand whether audio behaviour is correct, stable, and release ready. You'll work closely with Audio SDK engineers and platform teams to turn complex audio quality problems into measurable, repeatable engineering systems. The right person will have strong C/C++ and Python skills, practical digital audio knowledge, and experience building reliable tools, automation, or analysis systems. Previous testing or QE experience is helpful, but we're most interested in engineers who can write production quality code, reason about audio behaviour, and build systems that other engineers depend on.
Responsibilities
- Design, build, and maintain audio validation tools for PlayStation SDK audio libraries and technologies.
- Write C/C++ and Python code to analyse audio output, detect regressions, compare SDK versions, and validate expected behaviour.
- Build automated systems for repeatable audio quality measurement, including signal analysis, spectral comparison, latency checks, conformance checks, and regression detection.
- Create tooling that gives engineers clear evidence when audio behaviour changes.
- Work with Audio SDK engineers to understand features, risks, expected behaviour, and testability needs.
- Integrate audio validation into CI, build pipelines, reporting, dashboards, and release workflows.
- Investigate complex audio issues using debugging, data analysis, signal processing, and collaboration with domain experts.
- Own technical areas end to end, from requirements and design through implementation, documentation, maintenance, and support.
- Help define standards for maintainable, reproducible, and trustworthy audio validation tooling.
- Mentor engineers and share knowledge across SDK QE and Audio SDK teams.
Qualifications
- Strong professional software engineering experience.
- Strong C/C++ development skills.
- Strong Python development skills.
- Practical understanding of digital audio fundamentals (PCM audio, sample rates, channels, latency, dynamic range, filtering, resampling, encoding, frequency domain analysis).
- Experience building tools, automation, analysis systems, SDK components, test infrastructure, or developer facing systems.
- Strong debugging skills across code, data, tooling, environments, and pipelines.
- Ability to take ambiguous technical problems and turn them into robust, maintainable software.
- Experience with source control, code review, CI, and collaborative engineering workflows.
- Clear written and verbal communication, especially when explaining technical findings to engineers with different specialisms.
- Degree in Computer Science, Engineering, Audio Technology, Mathematics, Physics, or equivalent practical experience.
- Strongly preferred: experience with audio analysis, signal processing, or automated media validation; experience validating libraries, APIs, command line tools, SDKs, runtime systems, or platform level software; experience with automated regression detection and quality measurement; experience working with CI systems such as Jenkins, GitHub Actions, Buildkite, TeamCity, or similar; experience with test frameworks such as GTest, CppUnit, PyTest, or similar.
- Useful extras: Game audio, console audio, real time audio systems, middleware, audio engines, or SDK development; perceptual or objective audio quality approaches (loudness measurement, spectral comparison, null testing, impulse response analysis, latency measurement, glitch detection, dropout detection, PESQ, POLQA, or PEAQ); spatial audio, 3D audio, binaural rendering, ambisonics, HRTFs, object based audio, or immersive audio formats; performance profiling, numerical correctness testing, floating point tolerances, or cross platform determinism; dashboards, telemetry, reporting, or trend analysis; technical leadership, mentoring, or leading work across multiple teams.
Success
- Audio regressions are detected earlier through automated validation.
- Engineers have clearer evidence when audio behaviour changes between SDK versions.
- Audio quality checks are integrated into repeatable CI or release workflows.
- Key audio validation tools are documented, maintainable, and trusted by engineering teams.
- The team has a clearer technical strategy for audio quality measurement.
- You are recognised as a senior technical owner for audio validation systems within SDK QE.
