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 the Engine Systems team, you will innovate on the core diagnostic and reliability frameworks that form the backbone of Roblox’s engine. In this role, you will have the firsthand opportunity to design and build the essential systems that allow us to monitor, analyze, and optimize the Roblox experience across millions of concurrent users.

You Will:

• Navigate a wide spectrum of platform-specific constraints to report intricate details about system stability and performance.
• Own the end-to-end observability space, ensuring internal engineers can monitor and action every disruption to the user experience.

• Collaborate cross-functionally with Engineering, Data Science, Product, and Leadership to prioritize and chart the strategic roadmap for the team.
• Execute high-performance systems-level code across all supported devices, from mobile and desktop to major consoles.

You Have:

• 8+ years of professional industry experience with a proven track record of technical leadership.
• Exceptional proficiency in C++ and deep expertise in systems-level programming, specifically targeting large-scale environments.
• Extensive experience with at least one non-desktop platform (e.g. mobile or console).
• A commitment to accountability, with experience managing systems where a 0.1% regression is considered a significant and actionable event.
• An adaptive mindset, with a strong desire to explore new technologies and move beyond established comfort zones.
• Outstanding interpersonal skills, prioritizing team execution and collective success over individual contributions.

Additional Considerations:

• Specialized experience in developing observability tools, such as crash reporting or application performance monitoring (APM).
• Data-driven approach, with experience working alongside Data Science teams to make informed architectural decisions.
• Multi-platform expertise involving several mobile or console ecosystems.
• Systems-level rigor, with the ability to build highly reliable code that functions optimally under the constraints of a global-scale platform.
