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.

Get Access To All JobsPrincipal Full Stack Engineer CPT: Frequently Asked Questions
Does a Principal Full Stack Engineer role qualify for CPT?
Yes, if your degree program includes coursework in software architecture, distributed systems, or full stack development and the role requires that knowledge directly. Your DSO evaluates whether the work is an integral part of your curriculum, not just related to your field. Document the connection between specific courses and the job responsibilities before your authorization meeting.
Can I do CPT at the principal or staff engineer level as a student?
CPT has no restriction on job seniority. USCIS and your school care about the academic connection, not your title or level of responsibility. That said, some DSOs flag high-compensation senior roles for extra scrutiny on the curriculum-integration requirement. Prepare documentation showing your graduate coursework in systems design or engineering leadership supports the scope of the role.
How do I find Principal Full Stack Engineer employers who hire on CPT?
Migrate Mate lists engineering roles from employers with F-1 work-authorization history, which narrows your search to companies familiar with CPT documentation requirements. At the outreach stage, ask directly whether the recruiter has worked with CPT students before, since principal-level hiring teams vary significantly in their familiarity with DSO approval timelines.
Will full-time CPT as a Principal Engineer affect my OPT eligibility?
Full-time CPT totaling 12 months or more eliminates your OPT eligibility under USCIS regulations. Part-time CPT, defined as 20 hours per week or fewer, does not count toward this threshold regardless of duration. If this role is full-time and runs a full academic year, structure your authorization in semesters or negotiate reduced hours to protect your post-graduation OPT window.
What should my I-20 say for a Principal Full Stack Engineer CPT authorization?
Your I-20 must list the employer name, work location, authorization dates, and whether the CPT is full-time or part-time. The employer name and location must match your offer letter exactly. DSOs issue a new I-20 for each CPT authorization period, and you cannot begin work until the updated I-20 is in hand. Mismatches between your I-20 and offer letter are a common source of compliance problems at E-Verify.
