Senior Software Engineer - Unreal Ecosystem

Riot engineers bring deep knowledge of specific technical areas but also value the opportunity to work in a variety of broader domains.

The UnEco (or Unreal Ecosystem) team has an impact on a wide array of topics, including gameplay features, runtime performance, tooling, CI/CD, just to name a few. As a Senior Software Engineer on the UnEco team, you'll drive existing technical processes with the team, as well as developing and refining them to improve efficiency.

The team collaborates globally with partners across Riot, all contributing to a stronger, more efficient Unreal development ecosystem. You’ll navigate diverse technical challenges - from build systems to editor tooling to runtime infrastructure - ramping up quickly on new domains and solving complex problems in ways that empower the developers who depend on your work. 

Responsibilities:

• Design and maintain shared libraries, plugins, and tools used by multiple game teams - balancing individual team needs against platform-wide consistency and maintainability.
• Contribute to technical roadmapping for platform capabilities, balancing immediate game team needs with long-term architectural direction.
• Design, build and maintain software systems with a focus on quality, reliability, and maintainability.
• Uphold a high standard of engineering excellence. Participate in code reviews, write unit/integration tests, and contribute to continuous improvement of team practices.
• Write clear documentation and communicate technical details across teams and disciplines.
• Participate in the on-call rotation; resolve live incidents & propose solutions in RCAs.
• Provide mentorship to more junior members of the team.

Required Qualifications:

• Bachelor’s degree in Computer Science, or a comparable field, or equivalent experience.
• 4+ years experience in professional software development.
• 3+ years of professional experience and proficiency with C++.
• Strong understanding of software engineering fundamentals (data structures, algorithms, concurrency, etc.).
• Experience operating across multiple codebases and teams simultaneously, rather than deep single-product ownership.
• Experience working in cross-functional teams and collaborating across disciplines.
• Strong communication within and across teams.

Desired Qualifications:

• Experience with Unreal Engine - particularly C++ plugin development, editor tooling, or build systems.
• Experience building developer tools, CI/CD pipelines, or internal platform infrastructure.
• Experience supporting or consulting with multiple product teams as a platform or tools engineer.
• Familiarity with game development workflows and pain points (understanding the domain helps you build better tools).

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 developers, this could be the role for you!

Working closely with Riot teams globally, Riot Sydney is a powerhouse of talent, and experts in global development. Our team works on VALORANT, League of Legends and Teamfight Tactics, alongside exciting R&D and Tech projects.
