Egofold is an AI initiative within Snail Games focused on building a modular AI brain ecosystem for NPC intelligence real-time perception systems and simulation tooling across multiple game projects.

About the Role

We are seeking a senior AI engineer to lead the development of Egofolds foundational AI systems. This role is responsible for building and structuring a reusable trainable LLM-based brain that can operate across multiple environments and contexts. The focus is on core system design and execution: how the AI reasons learns adapts and integrates training workflows over time. This is a hands-on role for someone comfortable making technical decisions under ambiguity and operating without fully defined requirements.

Job Type

Full-Time

Location

Hybrid Los Angeles Area (34 in-office days per week)

Responsibilities

• Design and implement foundational AI systems using large language models as a core reasoning component.

• Architect simulation-based learning systems and training workflows including fine-tuning reinforcement learning evaluation and feedback loops.

• Build validation safety and constraint layers around generative outputs to ensure predictable and controllable behavior.

• Define evaluation frameworks and benchmarking strategies to measure agent performance stability and learning progression over time.

• Structure how context memory and world state are represented and consumed within the AI architecture.

• Determine how learned behavior structured logic and rule-based systems interact within a unified hybrid system.

• Collaborate with engine engineers to integrate AI systems into real-time interactive environments.

• Make system-level technical decisions that prioritize long-term reuse scalability and cross-domain adaptability.

Minimum Requirements

• Significant professional experience building AI or ML systems beyond simple model or API integration.

• Demonstrated experience working with large language models in a production or applied research context.

• Hands-on experience with agent training methodologies including reinforcement learning or simulation-based learning systems.

• Strong understanding of training workflows evaluation strategies and iterative improvement cycles.

• Strong proficiency in Python and experience integrating AI systems into production environments.

• Ability to reason about complex stateful systems and learning behavior over time.

• Comfort operating in early-stage ambiguous environments and taking ownership of foundational systems.
