Description

Summary: Seeking a Senior UE5 C++ Gameplay Engineer passionate about leveraging Generative AI to create dynamic, interactive storytelling experiences. Highlights: 1. Pushing boundaries of interactive storytelling with cutting-edge technology 2. Developing dynamic gameplay systems using Generative AI 3. Building experiences, not just models, in UE5 C++ We are building the next frontier of interactive storytelling and player agency, pushing the boundaries of what's possible when creativity, intuition, and cutting\-edge technology come together. We are a dream team obsessed with the uncomfortable excitement of discovering what happens when traditional scripted boundaries are broken. We are seeking a **Senior UE5 C\+\+ Gameplay Engineer** who is passionate about leveraging Generative AI to create dynamic gameplay systems that respond to players in ways previously thought impossible. In this role, you won't just be building models; you'll be building experiences. **Responsibilities** * Design and develop runtime plugin architectures within UE5, including Build.cs configuration, module dependencies, and non\-editor code * Establish plugin boundaries and implement clean integration patterns across systems * Build real\-time audio streaming pipelines using USoundWaveProcedural, including PCM buffering and resampling * Handle sample\-rate and audio\-format conversion, underrun mitigation, and latency tuning * Implement WebSocket and streaming protocol integrations in C\+\+ with persistent session management and JSON\-based event protocols * Develop reconnection strategies and backpressure handling for robust network communication * Integrate LLM and conversational AI voice systems, including TTS/STT, prompt and session design, and turn\-taking logic * Architect event\-driven systems using decoupled delegates, event bus patterns, and Unreal subsystems * Wire cross\-system integrations across the codebase to support dynamic gameplay experiences * Integrate MetaHuman runtime lip\-sync systems, audio\-to\-viseme pipelines, and streamed audio into facial animation * Debug and profile audio and network layers by tracing raw protocol events and diagnosing quality, latency, and streaming issues **Requirements** * 3\+ years of professional experience in gameplay engineering with C\+\+ in Unreal Engine * Expertise in UE5 C\+\+ plugin/module development, including runtime plugin architecture, Build.cs configuration, and module dependencies * Knowledge of Lua, including scripting integration with C\+\+ and its application within gameplay or tooling systems * Proficiency in runtime (non\-editor) code and defining plugin boundaries and integration patterns * Background in real\-time audio streaming in Unreal Engine using USoundWaveProcedural, PCM buffering, and proper resampling * Skills in sample\-rate and audio\-format handling, underrun mitigation, and latency tuning * Competency in WebSocket and streaming protocol integration in C\+\+, covering persistent session management, JSON\-based event protocols, and reconnection strategies * Understanding of backpressure handling in networked streaming systems * Familiarity with libwebsockets * Knowledge of LLM and conversational AI voice systems, including TTS/STT integration, prompt and session design, and turn\-taking systems * Capability to investigate and debug latency in conversational AI pipelines * Qualifications in event\-driven architecture using decoupled delegates, event bus patterns, and Unreal subsystems, with cross\-system integration and codebase wiring * Showcase of MetaHuman integration work involving runtime lip\-sync systems, audio\-to\-viseme pipelines, and feeding streamed audio into facial animation * Proficiency in audio and network debugging/profiling, including tracing raw protocol events and diagnosing audio quality, latency, and streaming issues * Proficiency in English at an Upper\-Intermediate level (B2\) or higher **Nice to have** * Familiarity with StateTree * Experience with gameplay systems and components * Knowledge of multiplayer replication * Skills in Blueprints and animation systems **We offer** * International projects with top brands * Work with global teams of highly skilled, diverse peers * Healthcare benefits * Employee financial programs * Paid time off and sick leave * Upskilling, reskilling and certification courses * Unlimited access to the LinkedIn Learning library and 22,000\+ courses * Global career opportunities * Volunteer and community involvement opportunities * EPAM Employee Groups * Award\-winning culture recognized by Glassdoor, Newsweek and LinkedIn
