Every day, tens of millions of people come to Roblox to explore, create, play, learn, and connect with friends in 3D immersive digital experiences– all created by our global community of developers and creators.

At Roblox, we’re building the tools and platform that empower our community to bring any experience that they can imagine to life. Our vision is to reimagine the way people come together, from anywhere in the world, and on any device. We’re on a mission to connect a billion people with optimism and civility, and looking for amazing talent to help us get there.

A career at Roblox means you’ll be working to shape the future of human interaction, solving unique technical challenges at scale, and helping to create safer, more civil shared experiences for everyone.

Are you an engineer early in your career who wants to apply AI and ML to make large systems more reliable and scalable? We’re looking for Software Engineers to join the Reliability team at Roblox. In this role you will help evolve the systems that keep Roblox fast, reliable, and efficient, and you will learn alongside senior engineers who build infrastructure at global scale.

You’ll work with engineers on our team and in partner teams to build infrastructure that supports Roblox growth. If you like digging into hard technical problems and shipping solutions that hold up in production, we want to hear from you.

At Roblox, our vision is to reach 1 billion daily active users. As part of this team, your work will directly help us scale toward that goal.

You Will:

• Own well-scoped features and components inside multi-quarter projects that scale Roblox and make our systems more efficient, from design through production rollout.
• Build and improve systems that use AI and ML to scale services and workloads across multiple geographic regions.
• Find and fix performance and efficiency problems in production services, such as right-sizing workloads and tuning resource usage, using metrics and profiling data.
• Work with product and infrastructure teams to understand their problems and help solve them with software.
• Take part in on-call and incident follow-ups, and turn what you learn into lasting reliability improvements.

You Have:

• Experience: a BS degree (or equivalent professional experience) in Computer Science or a related engineering field, with at least 2 years of experience building backend systems or AI/ML pipelines (internships and research count).
• Coding skill: strong proficiency in at least one programming language (e.g., Python, Rust, Go, Java, C#), and you write clean, tested, maintainable code.
