Principal Software Engineer - Creator Distributed Systems & Storage

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.

As a Principal Software Engineer on Creator Services Data, you’ll be leading the company’s efforts to build the next generation Data Storage systems to power the millions of experiences on the Roblox Platform. We run the mission critical cloud services, Data Stores , Memory Stores , and Badges , which are crucial for storing game state such as inventory and scores, implementing leaderboards, server lists, and trading, and tracking player progress and achievements. Our team is also responsible for building dashboards to provide insights to Creators using cloud services including Client/Server Performance , Data Stores , and Memory Stores . Finally, our team owns the Roblox Extended Services platform, which provides the capability for large experiences to purchase additional resources for existing services like Data Stores and new services built around compute and generative AI.

At its core, this team is focused on solving complex back end distributed systems and storage problems at scale. However, our scope extends to full stack projects spanning all the way from the infrastructure layer, through data storage and data pipelines, microservices, telemetry, game servers, web development, UI, and UX design. This team collaborates on multiple cross-company efforts and our projects are of extremely high importance to Roblox.

• Expand the internal and customer facing cloud service observability capabilities through metrics collection, data pipelines, intelligent analytics, data visualization, and dashboards.


• Increase the capabilities and onboard new customers to the Roblox Extended Services platform.


• Work with our users (Creators) to identify product gaps and bugs and handle customer emergencies.


• Provide on-call support for our Data products including responding to production alerts and outages.


• Mentor junior engineers and provide technical and non-technical guidance through design and code reviews, joint projects, 1:1s, and peer feedback.


• Lead collaborations on a cross-functional team including UX design, product management, project management, developer relations, documentation, customer support, and other engineering teams.


• Become a recognized technical leader across the company and contribute to company-wide initiatives.

• Prior experience programming computer games, particularly in Lua/Luau


• Prior knowledge of data science, data analytics, machine learning, or AI


• Prior experience building graphical user interfaces, dashboards, or web application front ends

You Are:

• Innovative: We strive for novel solutions that bridge the technical needs of Roblox with the creative needs of our developer community. This typically involves tackling competing objectives and thinking creatively.


• Passionate: We are looking for new team members who are passionate about data storage technology, computer games, and software development. We are excited about building new products that will redefine the future of human online interaction.


• Versatile: The Data Pod is expanding its scope beyond providing low level storage solutions to building higher level services such as User Profiles and LiveOps Analytics. We are also working on projects such as Observability and Billing & Payments platforms. You need to be ready to learn new programming languages and tech stacks as we evolve.


• Responsible: Data Storage services cannot go down and cannot lose data. You are committed to join a team that strives for a 100% uptime and data durability.


• Team Oriented: You are ready to both guide and learn from others. You will set the standard on team collaboration and communication. You exemplify Roblox Values and Principles .
