UI Engineer - RuneScape: Dragonwilds

Location: Cambridge, UK – This position offers flexible working options, including predominantly remote work. Applicants are preferably based (or willing to relocate) within a comfortable commuting distance of our office to attend onsite as required.

We’re looking for a UI Engineer to join the RuneScape: Dragonwilds development team, owning gameplay‑facing UI systems from architecture through to implementation.

This is a hands‑on engineering role where you’ll work closely with designers, gameplay engineers, and UX to deliver new features, modernise existing UI, and create robust patterns that help the team build scalable, performant interfaces with confidence.

You’ll have the opportunity to shape how complex gameplay systems are surfaced to players, from abilities and attributes to cooldowns, status states, match flow, death, respawn, and spectating. The role goes beyond implementing screens: you’ll help define the technical foundations that make UI reliable, maintainable, and effective in a networked multiplayer environment.

What you’ll be doing:

• Build gameplay‑facing UI in Unreal using UMG, Common UI, and MVVM where appropriate.
• Create reusable widgets, frameworks, data flows, and tools that help designers iterate quickly.
• Connect UI to gameplay systems, including abilities, attributes, cooldowns, and player status.
• Refactor legacy UI into cleaner, more consistent, production‑ready systems.
• Work with designers and UX to turn player‑facing goals into practical Unreal solutions.
• Keep UI performant, reliable, and multiplayer‑safe under complex gameplay conditions.
• Debug UI, input, replicated state, and edge cases across core game flows.
• Help set UI engineering standards for architecture, naming, ownership, and Blueprint/C++ usage.

What we’re looking for:

• Solid experience with Unreal Engine development.
• Knowledge of UMG, Slate fundamentals, Blueprint/C++ integration, and the Unreal gameplay framework.
• Demonstrable experience integrating UI with GAS or similarly complex gameplay and state systems.
• Understanding of ViewModel usage, separation of concerns, and maintainable UI architecture.
• Track record of refactoring inherited UI codebases and improving technical structure.
• Strong experience working on multiplayer games.
• Experience with Unreal Viewmodel/MVVM plugin in production is a benefit.
• Experience with Common UI, input routing, platform UX, and UI tooling is a benefit.

What we offer:

• Private Healthcare, including Dental Plan.
• Discretionary annual performance bonus.
• Minimum 6% pension contributions.
• Life Insurance.
• Enhanced family leave policies from day 1.
• Flexible working hours.
• 25 days annual leave + bank holidays & the option to buy/sell holidays + so much more!
