Senior Software Engineer, Game UI - League of Legends

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.

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

Required Qualifications:

• 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

Desired Qualifications:

• 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

For this role, you'll find success through craft expertise, a collaborative spirit, and decision-making that prioritizes the delight of players. We will be looking at your past studies, experience, and your personal relationship with games. If you embody player empathy and care about players' experiences, this could be your role!

Our Perks:

And just like in our games, we’re better when we work together. Our goal is to create collaborative teams where you are empowered to bring your unique perspective everyday. If that sounds like the kind of place you want to work, we’re looking forward to your application.
