Our role at SIE is to create and nurture the experiences under the PlayStation brand, a name synonymous with entertainment excellence and creativity. Sony Interactive Entertainment is seeking a Senior Software Developer on a contract basis for an internal tooling team in Foundational Systems and Experiences Engineering (FSEE). We build tools that help internal development teams onboard, manage, and observe their application releases. Our goal is to reduce manual effort for application developers, quality engineering developers, and release managers while giving them a clearer view of application status and next steps. You will work directly with these users, from discovery and design through implementation, production support, and handoff. This is a hands-on full stack role for someone who enjoys making capable systems feel simple to use. Responsibilities Design, build, test, and maintain the centralized portal and supporting services that internal console development teams use to onboard new applications. Work with application developers, quality engineering developers, and partner teams to understand onboarding and development pain points, validate designs, and prioritize useful improvements. Create clear, accessible interfaces that show application status, required actions, and relevant signals from connected systems. Build secure, reliable backend services and APIs that integrate with systems involved in application onboarding and development workflows. Collect and track signals from those systems, then implement dependable checks that can be used as gates in CI/CD pipelines. Automate repetitive steps and surface actionable information to reduce manual coordination and errors. Add appropriate tests, logging, monitoring, and documentation; diagnose issues and improve performance and reliability in production. Make pragmatic architecture and implementation decisions, explain trade-offs, and contribute to code reviews and shared engineering practices. Complete an orderly transition with maintainable code, user guidance, operational documentation, and clear ownership for ongoing work. Required qualifications 5+ years of professional software engineering experience, or equivalent evidence of designing, shipping, and supporting production web applications. Strong JavaScript/TypeScript skills and experience with a modern frontend framework such as React, Vue, or Angular. Experience building backend services in Node.js, Python, or a comparable language, including REST or GraphQL APIs. Experience with relational or document databases, data modeling, and integrating multiple systems. Understanding of CI/CD pipelines and experience building or integrating automated checks into development workflows. Working knowledge of authentication, authorization, automated testing, and practical security and reliability practices for internal applications. Strong problem-solving and communication skills, with experience collaborating across engineering and other partner teams and documenting technical work clearly. Preferred qualifications Experience building developer-focused tools, internal platforms, self-service workflows, or applications for technical users. Experience with containers, cloud services, or deployment automation relevant to operating internal applications. Experience designing automated gates from signals produced by multiple systems. Experience improving accessibility, usability, observability, or performance in internal products. Curiosity about AI-assisted development and where it can responsibly improve engineering workflows and tool usability. What success looks like Internal development teams can onboard new applications through the centralized portal with fewer manual steps. Signals from connected systems are visible and reliable enough to support the agreed CI/CD gates, with clear handling for missing or inconsistent data. The delivered tools are secure, usable, tested, and observable. Users and partner teams have clear documentation and a way to provide feedback. The owning team has maintainable code, recorded decisions, and a complete handoff for ongoing work.
