Senior Machine Learning Engineering Manager

Roblox Roblox · Consumer · San Mateo, CA · Software Engineering

Senior Engineering Manager for Safety AI Systems at Roblox, leading a team to develop innovative AI solutions for multimodal content safety. The role involves overseeing machine learning systems, constructing multimodal model architectures, improving data quality, training pipelines, and model performance for real-time content understanding and moderation using large vision language models across various content types (avatars, images, videos, audios, text, code/data). The goal is to detect and mitigate abusive behavior at scale, balancing user freedom with platform civility.

What you'd actually do

  1. Own the vision, technical direction, and execution of machine learning solutions for the Multimodal Safety AI system, ensuring these systems effectively detect and prevent harmful content at scale.
  2. Lead and grow a high-performing team of ML engineers, fostering a culture of innovation, technical excellence, accountability, and inclusivity, while mentoring and developing talent.
  3. Break down ambitious long-term goals into an actionable, iterative roadmap – delivering continuous improvements in stages and driving tangible value at each step.
  4. Architect and guide the development of large-scale machine learning models with innovative architectures, ensuring they achieve high quality and are production-ready.
  5. Drive alignment on complex technical decisions across multiple teams (within and beyond the Safety org), demonstrating empathy and building consensus among diverse stakeholders.
