Job Description

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.

If you believe that the Player Experience comes first, we want to hear from you. Our players are a diverse group from different backgrounds, and we want to see that reflected in the people who make our games, all qualified applicants will be considered for employment

Our Perks:

At Riot we strongly believe in work / life balance, and we encourage that with our open paid time off policy, paid parental leave (for both primary and secondary carers) and flexible work schedules to fit your lifestyle. We also believe that work should be fun, we have co-op gaming areas, a play fund so you can broaden and deepen your knowledge of players and community, and all the snacks you would ever need to power through your day (even healthy snacks!). And that’s not all we offer, there’s also:

• Medical Insurance that covers you and your dependents
• Employee Assistance Program
• Wellness fund
• Donation matching of time and money to registered charities
• Learning and Development opportunities
