Role overview

We’re looking for a Senior Software Engineer to build the tools and automated systems we use to validate audio technologies in the Play Station 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.

• What you’ll be doing
• Design, build, and maintain audio validation tools for Play Station 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.
• What we’re looking for

Essential

• Strong professional software engineering experience.
• Strong C/C++ development skills.
• Strong Python development skills.
• Practical understanding of digital audio fundamentals, such as PCM audio, sample rates, channels, latency, dynamic range, filtering, resampling, encoding, or 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, Git Hub Actions, Buildkite, Team City, or similar.
• Experience with test frameworks such as GTest, Cpp Unit, Py Test, or similar.
• Useful extras
• Game audio, console audio, real‑time audio systems, middleware, audio engines, or SDK development.
• Perceptual or objective audio quality approaches such as 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.

Benefits of working at Play Station

• Technology development is not constrained by a specific game or engine; there is space to research, prototype, and develop foundational technologies used across Play Station.
• Opportunities to collaborate with engineering and R&D teams across London, Tokyo, San Mateo, and the wider Sony group.
• Time and support to investigate new approaches, improve engineering systems, and contribute ideas that raise the quality bar.
• Opportunities to take part in global hackathons and cross‑team innovation projects.
• A relaxed working environment with a high level of trust and autonomy, where engineers are encouraged to express their views and challenge the status quo.

Benefits

• Hybrid working
• Discretionary bonus opportunity
• Private Medical Insurance
• Dental Scheme
• London Allowance (if applicable)
• 25 days holiday per year
• On Site Gym
• Subsidised Café
• Free soft drinks
• On site bar
• Access to cycle garage and showers
• Background checks and privacy
