Senior Software Engineer - Data Access

The Data Access team within Infra / Storage builds 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.

As a Senior Software Engineer you will work on some of Roblox’s hardest backend infrastructure challenges around scalability, reliability, workload governance, adaptive flow control, and distributed systems.

You Will

• 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, 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.

You Have

• Experience building large-scale infrastructure abstractions that standardize access to complex backend systems across broad engineering organizations.
• Experience designing or operating adaptive rate limiting, flow control, workload governance, or reliability automation systems in high-scale production environments.
• Experience operating or building systems around distributed databases, caching systems, OLTP platforms, or stateful infrastructure.
• Experience driving complex technical initiatives end-to-end with strong ownership and cross-functional collaboration.
• Strong hands-on experience building and operating large-scale distributed systems and backend infrastructure in production environments.
• Strong programming skills in Rust, Go, C++, Java or similar backend systems languages.
• BS degree (or equivalent professional experience) in Computer Science, with at least 6 years of hands-on experience.
