About The Position

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. We're looking for an outstanding engineer to join our Data Access team within Infra / Storage where we build EaaS (Entities-as-a-Service), Roblox’s large-scale managed OLTP access and management platform powering tens of millions of QPS across thousands of services. EaaS abstracts the complexity of distributed databases and caching systems behind a consistent and productive developer experience, enabling teams across Roblox to safely build and operate stateful systems at massive scale without requiring deep database expertise. The team operates at the intersection of distributed systems engineering, reliability engineering, and platform architecture — solving hard infrastructure problems that directly impact Roblox-wide scale and stability.

Requirements

1+ years of experience building large-scale backend or infrastructure systems.
An understanding of building systems that operate at high QPS with low-latency requirements is a plus.
Experience working on infrastructure or performance-critical backend systems is a plus.
Proficient in one or more programming languages (C#, C++, Go, Python or similar programming language).
Curious and passionate about solving open-ended problems.
Ability to identify challenges, develop a deep understanding of the systems involved, and drive solutions in collaboration with your team.
Strong Teamwork: Able to collaborate in cross-functional and cross team projects to deliver the most curated technical solution.
Long-term Mindset: Willing to take the long view to drive the collaboration and build the system.

Responsibilities

Build and evolve EaaS, Roblox’s managed OLTP access platform powering tens of millions of QPS across hundreds of services.
Design infrastructure that abstracts distributed databases and caching systems behind a consistent, safe, and highly productive developer experience.
Drive reliability and scalability improvements across distributed systems, including adaptive flow control, workload isolation and governance, efficient database usage and large-scale caching behavior.
Lead end-to-end technical execution architecture, implementation, rollout, production operations, and incident response for mission-critical infrastructure systems.
Analyze real production traffic patterns and failure modes to improve platform reliability, operational predictability, and scalability under rapidly growing workloads.
Improve platform safety, observability, deployment reliability, and operational excellence across the stack.
Partner with teams across Roblox to solve real scalability and reliability challenges for critical production workloads.
