Senior Software Engineer in Liverpool

Sony Interactive Entertainment (SIE) is a dynamic technology company delivering cutting‑edge hardware and network services to more than 100 million people. As a subsidiary of Sony Group Corporation, SIE builds the PlayStation brand and its associated IP, creating and nurturing experiences for a global audience.

Role Overview

As a Senior Software Engineer, you will create tools used by engineers, QA specialists, production teams, and studio partners around the world. You will remove friction from game development workflows and turn user feedback into reliable, high‑quality software. This role suits someone who enjoys practical engineering challenges, has an interest in games and tools development, and wants to see their work make a visible difference. You will work independently, contribute to technical direction, and may lead a small project or a significant part of a larger one. We value pragmatic engineers who can make thoughtful trade‑offs between quality, speed, maintainability, and long‑term technical health. Ideally, we would like someone to be present in our Liverpool office 2–3 days a week, but we can be flexible with remote working for the right candidate.

What You’ll Be Doing

• Design, develop, maintain, and improve tools, services, and pipelines.
• Own delivery from analysis and design through development, testing, release, support, and iteration.
• Contribute to technical design, including architecture trade‑offs, APIs, reliability, security, testing, and operational support.
• Refactor and optimise systems to reduce technical debt and improve performance, maintainability, reliability, and customer experience.
• Write high‑quality code, automated tests, documentation, and operational guidance.
• Improve engineering standards through code reviews, CI/CD, testing, release processes, and shared patterns.
• Partner with studios and cross‑functional teams to clarify needs, troubleshoot issues, support onboarding, and gather feedback.

What We Are Looking For

• Demonstrated senior‑level experience in relevant languages such as C++, C#, or similar.
• Strong understanding of software design, debugging, automated testing, source control, CI/CD, observability, and maintainability.
• Able to debug complex issues across code, systems, environments, integrations, and user workflows.
• Able to make thoughtful trade‑offs between delivery speed, quality, reliability, complexity, and customer value.
• Able to explain technical details clearly to technical and non‑technical audiences.
• Communicates clearly across time zones, disciplines, and levels of technical knowledge.
• Asks questions to understand root causes, customer needs, risks, and intended outcomes.
• Works through ambiguity constructively, focusing on shared goals and strong relationships.
• Applies pragmatic judgement, choosing approaches that fit the problem rather than following process or preference for its own sake.
• Supports and guides engineers, testers, tool users, and partner teams through reviews, pairing, workshops, and documentation.
• Looks beyond their own area to identify bottlenecks, improve practices, and support wider outcomes.
• Keeps learning, shares knowledge, and brings curiosity and care to the craft of building great software.

NICE TO HAVE

• Understanding of how to safely and effectively use generative AI to augment development work.
• Experience developing Windows applications within the games industry or building tools that support game dev workflows.
• Degree in Computer Science, Software Engineering, or equivalent.
