Riot Engineers bring deep technical expertise while embracing cross-disciplinary collaboration to deliver meaningful player experiences. As a Software Engineer III focused on Meta Systems, you will build and evolve the systems that shape a player’s journey outside of moment-to-moment gameplay — including progression, social features, quests, customization, and long-term engagement systems.

As a Staff Software Engineer on an unpublished R&D product, you will design and deliver robust metagame systems that connect gameplay, player identity, and progression. You will partner closely with design, UX, production, Services, and Foundations teams to implement scalable, maintainable systems that are performant in-engine and resilient across client-service and engine boundaries. You will independently own features from technical design through production readiness, ensuring high-quality execution in a live service environment.

Responsibilities:

• Design and independently drive the implementation of large-scale metagame systems (progression, social features, quests, customization) from technical design through high-quality execution and polish.
• Collaborate closely with Services and Foundations teams to integrate Meta systems with core backend and central services capabilities, ensuring scalable architecture and seamless persistence across client-service and engine boundaries.
• Develop clean, extensible C++ systems within Unreal Engine, emphasizing maintainability and performance, and translate UX specifications into functional in-game UI implementations.
• Build and maintain robust Unreal Editor tooling to empower designers and content creators to author and tune Meta systems efficiently.
• Ensure the long-term health and stability of the live service by proactively identifying and addressing technical debt, architectural gaps, and complex issues spanning client, engine, and backend systems.
• Elevate engineering quality across the team through active participation in code reviews and design discussions, and by mentoring junior engineers on best practices for C++ development and large-scale system integration.

Required Qualifications:

• 8+ years of professional software development experience
• Professional experience developing gameplay systems in Unreal Engine using C++
• Experience building or extending Unreal Editor tooling and workflows
• Experience implementing in-game UI systems based on UX or product specifications
• Strong understanding of software engineering fundamentals (data structures, algorithms, object-oriented design, concurrency)
• Experience collaborating effectively within cross-functional teams including design, UX, and production
• Experience integrating client gameplay systems with backend or platform services

Desired Qualifications:

• Experience building progression, social, or player customization systems
• Experience integrating gameplay systems with Player Platform or shared service ecosystems
• Familiarity with Unreal systems such as UMG, MVVM/View Models, Data Assets, Online Subsystems, or other foundational engine frameworks
• Experience working on or shipping a live multiplayer or online game
• Experience supporting post-launch feature iteration and live ops updates
• Experience building data-driven systems that empower non-engineering content authors
