This hiring is for the EY.ai Center for Reimagination, an AI-led innovation and engineering capability focused on building next-generation enterprise experiences, intelligent platforms and reusable technology assets for EY clients and internal transformation priorities.

The center brings together multidisciplinary teams across cloud, data, AI, experience design, application engineering and emerging technologies to rapidly prototype, industrialise and scale AI-native solutions across sectors. The role will contribute to this mission by strengthening Unity-led real-time simulation, interactive experience engineering, digital twin visualisation and immersive multi-screen solution capabilities.

The Opportunity

We are looking for a hands-on Senior Unity Developer with 7+ years of professional Unity experience to design and build enterprise-grade real-time simulations, interactive touchscreen applications, digital twin experiences and multi-screen visualisation solutions. The role will focus on developing robust Unity Engine applications using C#, Unity Animator/Mecanim, motion logic, API integrations and high-performance UI experiences.

The successful candidate will bring deep Unity and C# engineering capability, strong understanding of real-time simulation workflows, animation state machines, physics-based motion, IoT data streams and backend integration, with the ability to optimise frame rates, profile performance and deliver polished interactive experiences for client-facing innovation environments.

Your Key Responsibilities

• Design, develop and maintain Unity Engine applications using C# for real-time simulations, digital twins, interactive touchscreen interfaces and multi-screen experiences.
• Implement simulation logic, motion logic, physics-based animation, interaction flows, UI behaviours and data-driven visualisation components.
• Build and configure animation state machines using Unity Animator/Mecanim, including rigging workflows, motion capture integration and character or object movement systems.
• Integrate Unity applications with backend platforms, REST APIs, WebSockets, MQTT, IoT data streams and networking protocols for live and near-real-time experiences.
• Create reliable UI and backend integration patterns for data visualisation, telemetry dashboards, operational interfaces and interactive client demos.
• Optimise application performance through profiling, frame-rate tuning, memory management, asset optimisation and platform-specific performance improvements.
• Collaborate with designers, 3D artists, backend engineers, architects and product owners to convert storyboards, experience concepts and business requirements into production-ready Unity solutions.
• Support training simulation workflows, interactive walkthroughs, operational scenario modelling and enterprise experience prototypes.
• Apply clean coding practices, reusable component architecture, version control, code reviews, automated testing where relevant and technical documentation.
• Troubleshoot production issues, analyse runtime behaviour, resolve bottlenecks and improve stability, responsiveness and visual fidelity of deployed Unity experiences.
• Work in Agile Scrum delivery by supporting requirement clarification, backlog refinement, sprint planning, estimation, demos and retrospectives.
• Mentor junior engineers, promote engineering discipline and provide technical ownership for Unity-led experience delivery.
