Unreal Engine Plugin Developer (AI Agents) - Part-time - Worldwide

About the project

We’re building an AI agent system for Unreal Engine, focused on creating a plugin / editor tool that game developers can use to build better games. This is not a traditional game development role - the emphasis is on engine tools, plugins, and AI agent integration, not gameplay. This is an early-stage but tractioned project, and we’re looking for someone who can help rebuild and scale an existing prototype the right way, using Unreal best practices.

Core Responsibilities

• Design and build AI agents (primarily in Python) that can execute actions and interact with systems
• Integrate AI agents into Unreal Engine via plugins or editor tools (C++)
• Develop and maintain Unreal Engine tooling intended for other developers, not gameplay features
• Collaborate on agent architecture, including prompt handling, execution flow, and tool calls
• Improve, refactor, and productionize an existing prototype
• Help define technical best practices in a new and evolving problem space

Requirements (Priority Order)

1. AI Agent Development

• Hands-on experience building AI agents (preferably Python)
• Familiarity with agent frameworks, tool-calling, or MCP-style systems

1. Unreal Engine Expertise

• Strong experience with Unreal Engine (C++)
• Experience building plugins, editor tools, or engine extensions
• Comfortable reading and working with Unreal Engine source code

1. Web Development (Secondary)

• Familiarity with JavaScript, Node.js, or Next.js (nice to have)

Nice to Have

• Experience working directly with Unreal Engine source
• Background in game development (helpful, but not required)
• Experience building developer-facing tools or SDKs
• Comfort working in early-stage, experimental products

Why This Role Is Interesting

• Work on AI + Unreal Engine, a highly emerging and underexplored space
• Build tooling used by other developers, not just end users
• High ownership and influence on technical direction
• Strong potential for long-term collaboration as the product evolves
