Machine Learning Engineering Manager – Economy ML

Every day, tens of millions of people come to Roblox to explore, create, play, learn, and connect with friends in 3D immersive digital experiences– all created by our global community of developers and creators.

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.

The Economy ML team is building the machine learning backbone that powers Roblox’s Marketplace, Developer Monetization, and Payments ecosystems. From intelligent pricing and personalized storefronts to dynamic layout optimization and avatar understanding, we’re reimagining how the Roblox economy drives user engagement, monetization, and creator success at scale.

We’re looking for a Machine Learning Engineering Manager to lead a team of exceptional ML engineers tackling core challenges across ranking, retrieval, and multimodal content understanding. This includes everything from advancing deep learning models for search and recommendation, to developing systems that understand the textual and visual semantics of avatar content and drive long-term value for the Roblox economy.

You Will::

• Define and drive the technical roadmap for ML across Search, Recommendation, and Content Understanding.
• Lead the development of scalable, production-ready ML systems—from raw data to model deployment.
• Collaborate cross-functionally with product, design, and data science to build intelligent discovery experiences.
• Recruit, mentor, and grow a high-performing team of ML engineers.
• Establish engineering best practices to ensure system reliability, extensibility, and performance.

You Have:

• Leadership Experience: 3+ years managing ML engineers or scientists; 5+ years building ML systems at scale in search, recommender systems, or ads.
• Strong Technical Foundation: Degree in Computer Science, Engineering, Math, Physics, or a related field—or equivalent hands-on experience.
• Depth in ML: Proven track record shipping deep learning models across ranking, retrieval, NLP, computer vision, or multimodal pipelines. Experience using transformer architectures and LLMs in production systems is a strong plus.
• End-to-End Execution: You’ve built ML systems from data ingestion to serving in production.
• Strategic Thinking: You’re comfortable balancing near-term impact with long-term innovation.
• Team-first Mindset: A collaborative leader who thrives on mentoring and enabling others to succeed.
