Riot Engineers bring deep expertise in specific technical domains while embracing cross-functional collaboration to deliver exceptional player experiences.

As a Senior Software Engineer on an unpublished R&D project, you will focus on building and operating backend systems that power our social and store experiences. You will work closely with UI engineers, product, production, and central platform teams to deliver reliable, scalable services that directly impact players. This includes implementing high-load, highly available and secure client-server interactions that are fundamental to every player’s experience, as well as supporting the infrastructure, observability, and operational practices required to run a global live service. Additionally, you will help ensure our services are performant, resilient, and ready to operate at scale. You will report to a Senior Engineering Manager supporting the team within an R&D game project.

 

Responsibilities

• Design, implement, and maintain scalable backend services supporting social and store systems
• Own features spanning from service implementation to in-game integration
• Partner with product managers to identify and implement new backend services required to unlock novel features.
• Contribute to API design and client-server communication patterns optimized for high availability and efficient throughput
• Support live services, including operational readiness, monitoring, and incident response participation
• Implement and maintain infrastructure in support of new social and store features and optimize the cost of operations
• Design and implement internal web tooling and dashboards to support game operations, live service monitoring, or content management workflows (i.e., store catalog and offer management) for partner teams.
• Act as a technical liaison to shared platform teams for core integrations, ensuring reliable and performant client-server data flow.
• Participate in code reviews, design discussions, and continuous improvement of engineering practices
• Collaborate cross-functionally with design, QA, and production

 

Required Qualifications

• 5+ years of experience building backend systems, distributed systems, or game services
• Experience contributing to scalable, production-ready architectures
• Strong understanding of client-service architecture and service-oriented design principles
• Proficiency in Golang, C++, Java or another modern programming language
• Experience working with cloud platforms (e.g., AWS)
• Experience implementing observability practices including logging, monitoring, and diagnostics
• Experience building and maintaining internal web applications or tooling (e.g., using frameworks like Next, React, Angular, or Vue.js, or similar server-side rendering experience).

 

Desired Qualifications

• Experience working on or shipping an online multiplayer game
• Experience supporting or operating live services post-launch
• Experience working both in the game client and backend systems
• Experience with Unreal Engine
• Experience with AI assisted engineering workflows

For this role, success is grounded in technical craftsmanship, collaborative execution, and accountability in live service environments. We value engineers who understand how backend systems support social and store features, who can reason about operating distributed systems at scale, and who care deeply about delivering reliable experiences to players. We will consider your experience, technical depth, and connection to games when evaluating your application.
