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

Work Authorization Requirements

Applicants must be legally authorized to work in the United States at the time of application. This position does not offer visa sponsorship now or in the future (including H-1B).

Additional Information

As part of the Company’s activities in video game development, publishing, and short-form video content creation, certain projects, discussions, or creative materials may include themes, visuals, language, or subject matter that some individuals could find mature, violent, sexual, graphic, or otherwise sensitive in nature (collectively referred to as “Mature Content”). Examples may include, but are not limited to, depictions or descriptions of combat, violence, adult themes or relationships, suggestive or satirical humor, or strong language. Employees are expected to engage with such material in a professional and creative context as part of their job duties.
