Job Summary
As a Senior Machine Learning Engineer on the Economy ML team you will build models that power ranking personalization pricing and optimization across Robloxs economic surfaces including Marketplace Developer Monetization and Payments. Your work will directly shape how users discover virtual items how creators earn and how the platform grows sustainably.
The Economy ML team is building the machine learning backbone for Robloxs virtual economyfrom intelligent pricing and personalized storefronts to dynamic layout optimization and avatar content understanding. We partner closely with Marketplace Payments and Developer Monetization to deliver ML systems that drive longterm value across engagement retention and creator earnings.
You will:
- Work backwards from ambiguous product problems to design and ship endtoend ML solutions for ranking recommendation pricing and content understanding across Economy surfaces.
- Build and iterate on deep learning retrieval and ranking models that personalize item and widget ordering across the Marketplace and other shopping experiences.
- Develop models and policies that optimize pricing conversion and revenue while balancing ecosystem health payer experience and creator success.
- Own the full ML lifecycle for your projects: data exploration feature engineering model design training evaluation and production deployment on Robloxs ML platform.
- Design and run robust experiments (A/B tests and multicell experiments) tying your work to core metrics such as engagement bookings and creator earnings.
- Partner crossfunctionally with Product Backend Data Science Design and other Marketplace / Economy teams to define roadmaps requirements and success metrics for MLdriven features.
- Ensure the systems you build are scalable reliable observable and extensible including setting best practices around logging monitoring and oncall readiness for ML services.
- Contribute to the technical direction of the Economy ML team: help refine our modeling stack experimentation strategy and approaches to longterm reward optimization across the economy.
- Mentor other engineers on ML best practices code quality and experimentation helping raise the technical bar of the broader Economy organization.
You Have
- BS MS or Ph.D. in Computer Science Machine Learning Statistics or a related technical fieldor equivalent practical experience building ML systems.
- Experienced: 3 years experience with one or more of the following areas: search recommendation personalization pricing or content understanding systems for a highscale product.
- Fluent in the ML lifecycle: Comfortable taking a problem from messy data and product ambiguity through modeling evaluation and stable production deployment including building and maintaining data pipelines and feature stores.
- Deeply productoriented: You think in terms of impact on users creators and the business and you can reason clearly about how model choices affect metrics like LTV engagement conversion and creator earnings.
- Technically strong in modern ML: Handson experience with deep learning for ranking/retrieval representation learning for text and/or vision and largescale training/inference on distributed infrastructure.
You Are
- Experimentdriven: You are comfortable designing experiments diagnosing metric movements and iterating quickly while maintaining statistical rigor and healthy guardrails for the ecosystem.
- Collaborative and lowego: You enjoy working closely with engineers Product Managers Data scientists and designers across Marketplace Payments and Developer Monetization and you can drive alignment in complex multistakeholder environments.
- Creative and strategic: You take a longterm view of the Roblox economy are comfortable challenging assumptions and can balance quick wins with foundational investments in data infrastructure and modeling quality.
