Sony Interactive Entertainment (SIE) is the company behind the PlayStation brand. As a subsidiary of Sony Group Corporation, we’re part of a proud legacy of innovation and excellence. SIE is a dynamic technology company, delivering cutting-edge hardware and network services to more than 100 million people and an entertainment leader, home to some of the most beloved and recognizable intellectual properties (IP) in the world. Our role at SIE is to create and nurture the experiences under the PlayStation brand, a name synonymous with entertainment excellence and creativity. Staff Software Engineer, Adaptive Experiences Platform Waterloo, ON About the Role The DTIS Nurture organization is building the next generation of adaptive experiences for PlayStation. Our vision is to make every customer touchpoint more relevant, useful, and joyful by combining reusable experience capabilities with personalization, merchandising, experimentation, and intelligent decisioning. We are looking for a Staff Software Engineer to help lead the evolution of our Dynamic Experience Management, allowing teams to create and optimize experiences without requiring bespoke implementation for every client or a client release for every layout change. You will be a hands-on technical leader working across the experience stack. You will also shape the architecture needed to extend capabilities beyond PS5, across web, mobile, and other PlayStation devices. This is an opportunity to define foundational technology that will change how PlayStation builds, delivers, experiments with, and learns from customer experiences at scale. Responsibilities Define and drive the technical direction for our experiances SDK, translating the adaptive-experiences vision into an incremental, production-ready architecture. Lead the modernization of the PS5 Store experience runtime, including migration from legacy EMS SDK and client-specific rendering paths to schema-driven DXM experiences rendered through Content SDK. Design and evolve the platform-independent composition layer, public TypeScript APIs, versioned schemas, content adapters, component model, data bindings, and platform renderer contracts. Build reusable experience primitives and native rendering capabilities that support responsive layouts, personalization, experimentation, telemetry, accessibility, localization, and platform-specific interaction models. Establish safe coexistence and migration patterns, including backward compatibility, capability negotiation, validation, feature flags, fallbacks, rollback, and observability. Profile and optimize bundle size, startup and time-to-interactive performance, memory usage, rendering behavior, and runtime reliability on resource-constrained client platforms. Improve developer experience through clear interfaces, reference integrations, test harnesses, preview and debugging tools, automated compatibility testing, and high-quality documentation. Help establish governed, agent-assisted authoring and validation workflows that can translate design and business intent into trusted artifacts, supported by policy checks and evaluation suites. Partner with client, design system, merchandising, content, personalization, experimentation, and platform service teams to align contracts and deliver end-to-end capabilities. Provide technical leadership across team boundaries, mentor engineers, make sound trade-offs in ambiguous problem spaces, and communicate architecture and decisions to technical and non-technical stakeholders. Required Qualifications Bachelor’s degree in Computer Science, Software Engineering, or a related field, or equivalent practical experience. 8+ years of professional software engineering experience, including significant experience designing and delivering production client platforms, SDKs, frameworks, or shared libraries. Expert-level proficiency with TypeScript or JavaScript and strong experience with React, React Native, or a comparable component-based client framework. Strong software architecture and API design skills, including modularity, dependency management, versioning, backward compatibility, and incremental migration of large production systems. Experience building data-driven or server-driven user interfaces, reusable component systems, or runtime composition frameworks. Demonstrated ability to diagnose and improve client performance and reliability using profiling, telemetry, automated testing, and production observability. Experience designing for more than one client environment, such as console, mobile, web, TV, or embedded platforms, with a practical understanding of platform-specific constraints. Proven track record of solving ambiguous, cross-functional problems with minimal direction and driving alignment without relying on formal authority. Strong written and verbal communication skills, including the ability to document architecture and explain complex technical decisions clearly. Preferred Qualifications Experience with console development, living-room interfaces, focus-based navigation, or performance-constrained native clients. Experience with schema-backed declarative UI, domain-specific languages, JSON Schema, component expansion, data binding, hydration, or client-side rendering engines. Experience building or integrating client SDKs, content management or merchandising systems, personalization platforms, experimentation frameworks, or design systems. Experience migrating a large client application away from a legacy rendering or content-delivery framework using staged rollout, compatibility layers, and measurable exit criteria. Experience developing platform adapters or renderers for iOS, Android, web, or other native client environments. Familiarity with content and layout separation, runtime content sources, telemetry provenance, accessibility, localization, a
