Senior UI Technical Designer; TEMP – Unannounced Game

Senior UI Technical Designer

At Blizzard, we craft genre‑defining games and legendary worlds for all to share. Through unparalleled creativity and storytelling, we create immersive universes and iconic experiences that are beloved across platforms, borders, backgrounds, and generations.

We are looking for a Senior UI Technical Designer to help craft a new, unannounced game. This is a temporary position lasting 6 months with a flexible hybrid schedule from our Irvine, CA studio. Hybrid is the standard arrangement, but you may also work on‑site full‑time if preferred.

This role bridges UI design and engineering, enabling designers to build expressive, scalable, and high‑performance UI with minimal engineering dependency. You will define and implement a technical UI foundation that supports fast iteration and allows designers to own and evolve the UI. You must be comfortable operating in a dynamic environment, navigating fluid deadlines and changing priorities with purpose.

• Design, implement, and support UI systems and workflows that empower designers to independently create and modify UI content.
• Serve as the technical bridge between UI design and engineering, translating design needs into effective, practical solutions.
• Build and maintain UI layouts, styles, and behaviors using Unity UI systems, including UI Builder and Visual Scripting.
• Partner with UI Engineers to ensure UI systems are scalable, maintainable, and performant across platforms.
• Collaborate closely with artists, designers, and audio to ensure UI visuals, motion, and feedback are cohesive and production‑ready.
• Diagnose, debug, and resolve UI‑related technical issues within the engine.
• Create and maintain clear documentation and best practices to support consistent adoption of UI workflows.
• Anticipate UI technical risks and evolve systems to support future content, tooling, and team needs.

• 8+ years of professional game development experience focused on UI design, technical design, or UI implementation, including shipping at least one AAA game with significant UI scope.
• Hands‑on experience designing, implementing, and iterating on UI systems directly in a game engine.
• Strong understanding of modern game UI architecture, workflows, and best practices, supporting scalable and maintainable systems.
• Hands‑on experience with Unity UI systems, including UI Builder, layout tools, data‑driven UI concepts, and visual scripting or similar tools.
• Solid scripting ability (e.g., C#, Lua, or equivalent) to support UI systems and behaviors when needed.
• Strong debugging and problem‑solving skills, particularly related to UI implementation, performance, and stability.
• Proven experience collaborating across disciplines, including design, engineering, art, and audio.
• Excellent communication skills, with the ability to explain technical concepts clearly to non‑engineers.
• A designer‑first mindset, strong ownership mentality, and a collaborative approach when working in ambiguous, evolving technical environments.

• Experience working on data‑driven or MVVM‑style UI systems.
• Experience supporting live‑patchable UI content and addressable asset workflows.
• Familiarity with accessibility considerations in UI design.
• Passion for a wide variety of game genres and platforms.

• Portfolio or examples demonstrating UI systems, workflows, or in‑engine UI implementation.
