About Snail Games USA

Snail Games strives to create the new high bar for gameplay experience in online gaming. We have been a global developer and publisher of digital entertainment since 2009 and are committed to pushing the boundaries of the industry.

About Egofold

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 Front-End/UI Engineer to design and build the interfaces through which users interact with Egofold’s agent systems. This includes internal tools for developers and designers, as well as future user-facing systems for configuring and controlling AI agents.

This role is not focused on static UI implementation alone. You will help define how complex AI systems—such as agent state, memory, decision-making, and training workflows—are exposed in intuitive, usable ways. The goal is to make powerful systems understandable and controllable.

Responsibilities

• Design and implement user interfaces for interacting with AI agents, simulation tools, and system outputs
• Translate complex system state (agent reasoning, memory, perception) into clear, usable visual representations
• Build responsive, real-time Front-End & UI components for monitoring and controlling agents
• Collaborate closely with Tools, AI, and Systems engineers to define workflows and user interactions
• Contribute to design decisions around usability, clarity, and interaction models
• Iterate on interfaces based on internal usage and feedback

Minimum Requirements

• Strong experience building modern UIs (web or desktop) using frameworks such as React, Vue, or similar
• Ability to design intuitive interfaces for complex or technical systems
• Experience working with real-time data or interactive systems
• Strong understanding of UX principles and usability
• Proficiency in JavaScript/TypeScript and frontend architecture

Nice to Have

• Experience building tools for developers, designers, or technical users
• Familiarity with game engines, simulation tools, or AI systems
• Experience visualizing complex system state (graphs, timelines, debugging tools)
• Interest in human-AI interaction or agent interfaces

Why Join the Studio Sirens Team?

• True focus on work/life balance
• Paid company holidays, vacation, and separate sick leave
• Medical, dental, vision, and Life/LTD
• 401k with company match
