Principal AI/ML Engineer, Reliability

• Define the strategy of leveraging Machine Learning Engineering to improve Production Systems Reliability at Roblox. - Improve realtime anomaly detection capabilities by leveraging various state of the art ML techniques, thereby directly contributing to improving Mean Time to Detect Production issues. - Develop methods to build pipelines to consume various streams of data (metrics, logs, traces, change management systems etc.). - Build a reasoning layer that interacts with the streams of data to find possible root causes of problems happening in production. - Build time-series models to predict capacity exhaustion and seasonal traffic spikes to drive automated scaling

You have:

• Beyond off the shelf:  We are looking for an expert who has knowledge of various modeling techniques, ability to go deep and fine tune models to fit our use cases. - Ability to propose and architect the infrastructure that allows us to implement systems that learn from user and/or automated feedback. - Good distributed systems fundamentals and understanding of large scale high throughput systems

You are:

• Comfortable with Ambiguity: You thrive in undefined or open-ended problem spaces, providing structure, clarity, and decisive direction to your teams. - A Pragmatic Builder: You are scrappy and impact-oriented. You view undefined data and messy systems as opportunities to build structure rather than blockers to progress. - An Inspiring Leader: Passionate about developing the next generation of technical leaders, managers, and engineers. - An Executive Communicator: Highly effective at communicating complex technical concepts to both engineering teams and non-technical executive leadership. - Data & System Oriented: You understand that robust data and systems are the foundation of any production application, and you design infrastructure for scale, correctness, and reliability. - Curious & Creative: You enjoy tackling hard problems, exploring new technologies, and driving continuous improvements in both systems and workflows.
