Job summary

EPAM Systems Inc. is seeking a Senior UI Engineer to build and maintain player-facing UI in Unreal Engine for a cross-platform live product.

You will craft reliable UI at runtime, integrate with gameplay systems and data sources, and ensure strong performance across input methods. Responsibilities include implementing UI screens and flows, owning end-to-end UI behavior, and collaborating with design to deliver maintainable UI.

Qualifications

• 5+ years shipping UI in Unreal Engine with UMG and Blueprints.
• Strong UI architecture knowledge: modular components, state management.
• Experience with cross-platform UI navigation and accessibility considerations.
• Proficiency with version control (Perforce preferred).

Responsibilities

• Implement UI screens, flows, and reusable components in Unreal Engine (menus, overlays/HUD, modal flows, lists/grids, etc).
• Own UI behavior end-to-end: navigation, focus management, input handling, state transitions, and error handling.
• Integrate UI with asynchronous data sources (client services/APIs, player data, remote config), including caching and loading states.
• Partner with UI design and UI art to translate specs into shippable implementations.
• Debug and optimize UI performance and stability (frame time, hitching, memory, draw cost).
• Help establish best practices and patterns for UI development.

Job description

We are looking for a Senior UI Engineer to implement and maintain player-facing UI systems in Unreal Engine for a cross-platform, live product. The role focuses on building reliable, scalable UI at runtime, integrating UI with gameplay/client systems and online data, and ensuring strong performance and usability across input methods.

Responsibilities

• Implement UI screens, flows, and reusable components in Unreal Engine (menus, overlays/HUD, modal flows, lists/grids, etc)
• Own UI behavior end-to-end: navigation, focus management, input handling (controller/keyboard-mouse), state transitions, and error handling
• Integrate UI with asynchronous data sources (client services/APIs, player data, inventory-like data, remote configuration), including caching and resilient loading states
• Partner closely with UI design and UI art to translate specs into shippable, maintainable implementations
• Debug and optimize UI performance and stability (frame time, hitching, memory, draw cost)
• Help establish best practices and patterns for UI development

Requirements

• 5+ years of proven experience shipping UI in Unreal Engine using UMG (Widget Blueprints) and Blueprints
• Strong understanding of UI architecture: separation of concerns, reusable components, state management, and event-driven/asynchronous flows
• Experience building cross-platform UI navigation (focus-driven UI, back behavior, input routing, accessibility/readability considerations)
• Ability to profile and troubleshoot performance issues using Unreal tooling (e.g., Unreal Insights and relevant in-engine debugging tools)
• Familiarity with professional team workflows: code reviews, ticket-based delivery, and version control (Perforce strongly preferred, Git acceptable depending on project)
• English proficiency at B2 level or higher

Nice to have

• Skills in C++ in Unreal Engine (extending UI frameworks, building base classes, performance-critical improvements)
• Familiarity with Unreal UI frameworks such as CommonUI/CommonInput and/or Slate
• Experience on a live-service product (rapid iteration, hotfix mindset, telemetry/analytics awareness, feature flags/remote config patterns)
• Experience collaborating across multiple disciplines (design, UI art, backend/services)
