Principal Software Engineer, Crash Reporting

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 complex platform limitations across various vendors (e.g. Apple, Microsoft, Google, Sony, etc.) to extract intricate details regarding hangs, crashes, and session health that enables all teams to safely ship changes to Roblox clients on all our supported platforms.

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.
• Develop systems with exceptional reliability and instrumentation that the entire organization trusts at Roblox’s massive scale.
• 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.
• Professional mentorship capabilities to guide high-performing engineering teams.
