Software Engineer, Account Authentication

Location: San Mateo, CA, United States

Department: Early Career FT - Engineering

As a Software Engineer on the Account Authentication Team, you will help authenticate and authorize Roblox's user base, setting the foundation for every other feature on our platform.
You will build the authentication and security controls that meet each user's needs, along with just-in-time friction that adapts to each user's unique risk profile, all while scaling to 1 billion active users.

This is a rare opportunity to sit at the convergence of security, user experience, and scale. You'll join Roblox's Safety organization, whose mission is to become the leader in civil immersive online communities by detecting, removing, and preventing problematic accounts, content, and behavior, and by keeping accounts secure and free from compromise. The team draws on a broad tech spectrum, including machine learning, classifiers, experimentation, automation, and AI-powered filters, partnering with product teams to shape the roadmap, build safety products, and measure impact on our community of users and developers.

You Will:

• Own the design, implementation and landing of features that make Roblox more secure and more accessible for users of all ages on all platforms.
• Collaborate cross-organizationally with partner teams in Growth, Discovery and the broader Roblox Safety org.
• Help define how goals get accomplished and have real influence over product direction.
• Influence how users first experience Roblox, often forming their baseline expectations for what security should look like on the internet.
• Instrument and analyze user interaction data (A/B tests, usage metrics) to inform design decisions and maximize product impact.
• Own implementation end to end across the stack, contributing in Rust, C++, and Lua as projects require, using AI tools wherever possible.

You Have:

• 1-3 years of experience in Software Engineering/Computer Science
• Experience working on user facing applications or services
• Proficiency in one or more programming languages such as Rust, C#, and Javascript.
• Experience collaborating cross-functionally with Product stakeholders to define requirements and deliver technical solutions.
• A strong commitment to designing, implementing, and maintaining systems that prioritize user safety, data integrity, and compliance with safety policies.
