Gameplay & UI Engineer, AI Agents

About the role

Mission Systems, the AI arm of Mission Group based in Singapore, builds Launchpad, a unified AI agent platform where agents work alongside people. As Gameplay & UI Engineer, you will design how people and AI agents interact in Launchpad, owning the interface layer end to end: interaction design, real-time feedback, dynamic agent-generated UI and mobile. The team is small, with a direct line to the founder.

Key responsibilities

• Design and build how people and agents interact: how an agent shows its intent and progress, hands work back, and takes correction.
• Build a dynamic UI system where agents assemble interfaces at runtime from a component library.
• Define the component library and the rules agents follow when composing it, so generated screens stay readable, consistent and fast.
• Build the Launchpad mobile app, which is glanceable, fast and reliable on the move.
• Own the feel: latency, feedback, animation and state transitions.
• Make onboarding feel like a good first level so users are productive in minutes without training.
• Prototype quickly, test with real users, instrument everything and iterate like a live game.
• Apply game AI thinking (behaviour trees, utility AI, simulation) to make agent behaviour legible and predictable.

Required profile

• Game development experience, ideally at a notable studio (AAA or a top mobile or indie studio), with at least one shipped title.
• Experience shipping gameplay or UI systems in production titles, with a strong sense of game feel.
• Understanding of game AI and simulation, and a strong intuition for where AI agents are heading.
• Always building: a prototype, mod or side project in progress.
• Creative, first-principles thinking, exceptional taste in interaction and visual design, and close collaboration with designers and artists.

Required skills

• Strong fundamentals in C++, C# or TypeScript, willing to work across web and mobile (TS/JS/React, NextJS).
• A portfolio or GitHub showing what you've built.
• Plus points: UI or tools programming, live-service or mobile games, procedural or data-driven UI.
• Plus points: hands-on experience building with LLMs or agent frameworks.

What we offer

• Competitive base salary plus performance-based bonuses.
• Discounted access across Mission Hospitality's portfolio of brands in Singapore.
