Never send money to companies. Jobs on Himalayas will never require payment from applicants.

As a member of Big Huge Games, you will be part of a highly skilled and innovative group responsible for creating world-class mobile games. Candidates should combine strong software engineering fundamentals with a passion for user experience, visual polish, and collaboration across disciplines. Your work will directly shape how players interact with our games, from moment-to-moment usability to overall presentation and feel.
You will work closely with artists, designers, and other engineers to implement, refine, and iterate on user interface systems within Unity. This role is ideal for engineers who enjoy bridging the gap between creative intent and technical execution—taking UI concepts, assets, and feedback, and turning them into responsive, performant, and maintainable in-game interfaces. We are looking for engineers who can collaborate effectively with non-programmers, communicate clearly about technical constraints, and iterate quickly to achieve the desired player experience.

Responsibilities

  • Implement and maintain in-game UI systems using Unity, based on designs and assets provided by the design and art teams
  • Work closely with UI/UX designers and artists to integrate visual assets, layouts, animations, and interactions into functional UI elements
  • Iterate on UI implementation based on feedback from design, art, production, and playtesting
  • Translate design intent into practical, performant UI solutions while providing technical feedback and guidance when needed
  • Develop UI code that is clean, maintainable, and scalable across different resolutions and platforms
  • Debug and resolve UI-related issues, including layout problems, visual inconsistencies, and interaction bugs
  • Collaborate with client, server, and tools engineers as needed to integrate UI with gameplay systems and backend data
  • Participate in code reviews and contribute to UI and client-side engineering best practices
  • Help ensure UI systems meet performance, usability, and visual quality standards

Requirements

  • Bachelor’s degree in Computer Science or equivalent engineering track, or equivalent professional experience
  • 3–5 years of experience in software engineering, game development, or a related role
  • Professional experience developing user interfaces in Unity
  • Strong understanding of how to collaborate with artists and designers to implement and refine UI elements
  • Experience integrating art assets into functional UI systems and iterating on them to meet design goals
  • Solid software engineering fundamentals, including the ability to write maintainable and robust code
  • Ability to quickly understand and work within an existing codebase and UI architecture
  • Strong problem-solving skills and attention to detail, especially around visual and interaction fidelity
  • Clear written and verbal communication skills and strong interpersonal collaboration abilities

Bonus

  • Experience with Unity’s UI Toolkit
  • Familiarity with UI architecture patterns and best practices in game development
  • Experience supporting UI across multiple screen resolutions and platforms
  • Experience working on live or content-driven UI systems
  • Background in mobile or free-to-play game development
  • Familiarity with UI animation or interaction polish workflows
Our headquarters are located in Timonium, MD. While we prefer MD-based candidates, with mutual agreement, we can accommodate a remote work environment in the United States for candidates from a few approved states.
