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.

Why Discovery:

With Roblox’s daily active users growing at a record pace, we are seeking senior data engineers to join the Search & Discovery team in building the next generation of data and ML feature infrastructure that powers real-time content discovery and recommendation. Our team fuels some of the most used surfaces of the app, including Home, Search, Notifications, and more, through high-scale, high-throughput data systems that shape ML-driven personalization.

 

As a Senior Software Engineer on our team, you will architect and build foundational data pipelines, real-time streaming systems, and scalable feature computation frameworks. Your work will enable rapid experimentation, empower ranking models, and support personalized content delivery at massive scale. You will collaborate closely with engineers across ML, backend, and analytics to shape the future of search and discovery infrastructure at Roblox.

 

Our mission is to connect a billion users with the best content and connections at the right time. We tackle diverse challenges in data engineering, experimentation, and distributed systems, at an unprecedented scale and velocity.

You Will:

Build high-performance data pipelines and real-time streaming systems that support both online and offline ML features, training data and statistical computation at scale. Design and scale robust data infrastructure for powering retrieval, ranking of various recommendation systems across major Roblox surfaces. Ensure data systems are reliable, observable, privacy-compliant, and performant under heavy concurrency and high throughput. Partner with ML and backend engineers to define scalable interfaces and enable rapid iteration for model development and experimentation. Contribute to internal platforms and tools that abstract complexity, improve developer productivity, and accelerate innovation.

You Have:

6+ years of experience building and scaling backend systems with a focus on data pipelines, infrastructure, and big data technologies like Spark, Flink, Kafka, and Hive. Proficiency in one or more programming languages such as C#, Go, Java, or Python, and experience managing compute at scale with Kubernetes. Strong understanding of data modeling, privacy-aware data processing, and performance optimization in large-scale environments. Experience building feature platforms or ML data pipelines in production environments. A graduate degree or equivalent experience in Computer Science, Engineering, or a related technical field is a plus.

You Are:

Data & System Oriented: You understand that robust data is the foundation of great ML systems, and you design infrastructure for scale, correctness, and reliability. Collaborative: You thrive in cross-functional teams, partnering effectively with ML, backend, and product engineers to solve complex challenges. Curious & Creative: You enjoy tackling hard problems, exploring new technologies, and driving continuous improvements in both systems and workflows. Impact Driven: You focus on outcomes - prioritizing product impact, reliability, and measurable success over code volume or complexity.
