United Kingdom London

Sony Interactive Entertainment isnt just the Best Place to Play its also the Best Place to Work. Were 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.

Role overview

Were 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. Youll 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.

Youll 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 were most interested in engineers who can write production-quality code reason about audio behaviour and build systems that other engineers depend on.

The team

The SDK Quality Engineering team is part of the Foundational Systems and Experiences Engineering group in London.

We work on low-level SDKs and core platform technologies used by game developers building Play Station games. This role focuses on audio technologies within the Play Station SDK including libraries tools runtime behaviour and platform-level audio features.

Youll work close to both engineering and quality. The goal is to make audio behaviour measurable regressions easier to detect and release decisions better informed.

What youll 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 were 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…
