ENGINEERING - UNREAL ENGINE
What We Do
Unreal-powered projects have been on the bleeding edge of real-time entertainment for over 20 years. Our team of engineering experts are always innovating to improve the tools and technology that empower content developers worldwide.
What You'll Do
We're looking for a Principal Al Engineer who builds products that integrate Al into Unreal Engine. You'll design and ship the full stack of systems that let LLMs act inside the engine (from end to end, not just a single layer), bringing depth in game engine architecture, cloud services, and how LLMs actually work.
In this role, you will
Design and build LLM-driven agents and tools that operate directly inside Unreal Engine, including engine-side C++/Python tooling and editor scripting
Architect and extend the cloud-hosted agent harness, services, and database that mediate between LLMs and the engine
Work across the full stack (engine tooling, cloud backend, and the web UI used to drive and monitor agents) to ship end-to-end features
Evaluate and integrate emerging LLM capabilities (tool use, multi-agent orchestration, context management) into Epic's engine and pipeline tooling
Define technical direction for the reliability, safety, and evaluation of LLM-driven engine automation
Partner closely with engine, tools, and backend engineers, and mentor others on both game engine internals and LLM system design
What we're looking for
Strong software engineering background with hands-on experience in a game engine (Unreal Engine strongly preferred), including engine architecture and tooling/editor scripting
Practical experience building or shipping products powered by LLMs (agents, tool-calling, RAG, prompt/context engineering), or a strong conceptual understanding of how LLMs work
Experience with cloud-native services and infrastructure: web APIs, databases, and service architecture and deployment
Excellent programming skills across C++ (engine-side) and Python and/or a web backend language
Ability to work full-stack and reason about tradeoffs across engine code, backend services, and a web front end
Excellent written and verbal communication skills
BS/MS in Computer Science or a related field
