Who you are

- Strong software programming 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 programming), or a solid 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

What the job involves

- We're looking for a Principal Al Programmer 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

- Design and build LLM-driven agents and tools that operate directly inside Unreal Engine, including engine-side C++/Python tooling and editor scripting

- Design 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 programmers, and mentor others on both game engine internals and LLM system design
