Software Engineer, Reliability

Roblox operates a global platform for 3D immersive digital experiences, focusing on tools that allow developers to create and share interactive content. The Reliability team is responsible for maintaining the platform's speed, efficiency, and stability as it scales to support a massive, growing user base. As a Software Engineer in this department, you will focus on building and improving infrastructure, often integrating AI and machine learning to optimize service performance across geographic regions. Daily responsibilities include designing and rolling out system components, profiling production services to identify efficiency gaps, and participating in incident resolution to implement long-term reliability improvements. You will work closely with cross-functional product and infrastructure teams to address technical challenges and contribute to code reviews and documentation. This role is well-suited for early-career engineers who possess a strong foundation in distributed systems, backend development, or AI/ML pipelines. Candidates should be comfortable working with metrics and profiling data to tune system performance and demonstrate a proactive approach to solving complex, large-scale technical problems while learning from senior team members.
