Senior Software Engineer, Game UI - League of Legends

Riot Games • Los Angeles, CA

20d • Hybrid

About The Position

As a Senior Software Engineer on the League of Legends team, you will own and deliver meta experiences that help new and returning players feel welcome and engaged — including onboarding tutorials, events, and UI/UX systems.
This is a hands-on role. While you’ll help guide technical direction, architecture, and mentor other engineers, you’ll also spend a significant portion of your time designing and implementing features yourself — with a strong emphasis on UI/UX development. You’ll also have opportunities to work across the full stack, from frontend experiences to backend services, making this role ideal for a generalist who thrives on building end-to-end systems.
You will report to the team’s Engineering Manager and work in a hybrid environment from our Los Angeles office.

Requirements

• 3-5+ years of professional software engineering experience, including experience delivering live or shipped products at scale
• Strong proficiency in C++ with experience in large, complex codebases
• Hands-on experience with UI/UX development in games
• Generalist mindset with the ability to contribute across the stack (gameplay, client UI, backend services)
• Proven track record of shipping player-facing features in live or large-scale games
• Strong communication skills and ability to work across disciplines
• Bachelor’s degree in Computer Science or equivalent experience

Nice To Haves

• Experience with full-stack game development, including backend service integration
• Background in tutorials, onboarding systems, or player journey-focused experiences
• Familiarity with Unreal, Unity, or other commercial game engines
• Exposure to A/B testing frameworks
• Deep familiarity with League of Legends or strong motivation to learn and play

Responsibilities

• Contribute heavily to technical design, architecture, and implementation of new features with a focus on UI/UX systems and player-facing features
• Collaborate with designers, product managers, and artists to build engaging tutorials, events, and meta systems
• Partner with service and backend teams to integrate end-to-end solutions that improve player onboarding and retention
• Champion and uphold engineering best practices — testing, maintainability, scalability, and documentation
• Mentor and coach engineers on technical execution, craft quality, and cross-discipline collaboration
