Riot engineers bring deep knowledge of specific technical areas but also value the opportunity to work in many broader domains. As a Software Engineer, you'll work with both new and current technology, creating creative solutions to overcome high-volume obstacles and to bring player value.

As a Principal Software Engineer on the UI Tooling team, you will develop against the foundations of the UI frameworks and authoring tools used to build experiences for League of Legends. The scope of this position requires collaboration with technology owners and content teams across the organization to ensure we provide thoughtful tools and workflows that help engineers, designers, and artists create and iterate effectively. For this role, you’ll report to the organization’s Engineering Manager. You will also partner with other teams and disciplines to ensure that your work improves the quality of life and effectiveness of those partners. Our platform is written in C++ and makes heavy use of the Qt ecosystem for UI/UX, with Python supporting several utility and workflow needs. This role will be based out of our Los Angeles Headquarters.

Responsibilities:
  • Work and align with different partners that span across multiple teams to ensure we're delivering awesome features to excite them
  • Contributing to technical discussions/designs that your team oversees
  • Own the software lifecycle for your code that includes develop/test/deploy/maintaining frameworks, platforms, and tools
  • Mentorship. You help junior Rioters develop the tools and creative atmosphere to shine
  • Participate in the team's support rotation
Required Qualifications:
  • 8+ years of deep hands-on experience with C/C++ that spans several use-cases and platforms.
  • At least 5 years of experience in the video game industry that includes working within multiple game development UI and an example of a shipped game. 
  • Have been responsible for driving the development of several organizational sized development efforts (1-year+ scope), including requirements gathering, planning, and testing.
  • Maintained software development best practices within your organization that includes design/code reviews, coding standards, source control management, testing, delivery performance, scalability, and maintainability
  • Experience working on a custom, internally developed game engine and tooling.
  • Expertise with UX artist workflows 

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 the experiences of players, this could be the role for you!

Our Perks:

Riot focuses on work/life balance, shown by our open paid time off policy and other perks such as flexible work schedules. We offer medical, dental, and life insurance, parental leave for you, your spouse/domestic partner, and children, and a 401k with company match. Check out our benefits pages for more information.

At Riot Games, we put players first. That mission drives every decision in our quest to create games and experiences that make it better to be a player. Whether you’re working directly on a new player-facing experience or you’re supporting the company as a whole, everyone at Riot is part of our mission. 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.

What you need to know about the Los Angeles Tech Scene

Los Angeles is a global leader in entertainment, so it’s no surprise that many of the biggest players in streaming, digital media and game development call the city home. But the city boasts plenty of non-entertainment innovation as well, with tech companies spanning verticals like AI, fintech, e-commerce and biotech. With major universities like Caltech, UCLA, USC and the nearby UC Irvine, the city has a steady supply of top-flight tech and engineering talent — not counting the graduates flocking to Los Angeles from across the world to enjoy its beaches, culture and year-round temperate climate.

Key Facts About Los Angeles Tech

  • Number of Tech Workers: 375,800; 5.5% of overall workforce (2024 CompTIA survey)
  • Major Tech Employers: Snap, Netflix, SpaceX, Disney, Google
  • Key Industries: Artificial intelligence, adtech, media, software, game development
  • Funding Landscape: $11.6 billion in venture capital funding in 2024 (Pitchbook)
  • Notable Investors: Strong Ventures, Fifth Wall, Upfront Ventures, Mucker Capital, Kittyhawk Ventures
  • Research Centers and Universities: California Institute of Technology, UCLA, University of Southern California, UC Irvine, Pepperdine, California Institute for Immunology and Immunotherapy, Center for Quantum Science and Engineering
