Job summary

Mission Systems in Singapore is hiring a Gameplay & UI Engineer to design how people and AI agents work together inside Launchpad. You’ll own the interface layer end to end, from interaction design and real-time feedback through dynamic, agent-generated UI for web and mobile.

You come from games with shipped titles and a strong feel for interaction and game UI. You’ll prototype quickly, test with users, and collaborate closely with designers and artists to ship crisp experiences.

Qualifications

• Shipped gameplay or UI systems in production titles.
• Strong game feel and ability to articulate interaction nuances.
• Understanding game AI and simulation.
• Hands-on prototyping and rapid iteration with users.
• Portfolio or GitHub showcasing builds.
• Ownership mindset and cross-functional collaboration.

Responsibilities

• Design and build how people and agents interact in Launchpad: how an agent shows its intent and progress, hands work back, and takes correction.
• Build our 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: 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.
