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.
WHY Voice Safety?
Safety and Civility is Roblox's #1 priority and our mission is to protect our community. As a Senior/Principal Machine Learning Engineer on the Voice Safety team, you’ll build systems that monitor real-time user interactions — including voice chat, in-experience communications, developer APIs, video, and more. We build world-class speech recognition and NLP models to keep conversations safe. Roblox’s voice safety systems currently process hundreds of thousands of hours of active voice data each day, flagging users for profanity, hate speech, personal information (PII), and other abuses within seconds to help ensure the platform remains safe and civil at all times.
You will:
- Build end-to-end ML systems to detect and address problematic voice communication and content on Roblox.
- Drive the evolution of our speech moderation into a scalable, adaptable system that supports dozens of customer teams with unique needs
- Develop innovative detection approaches in a rapidly evolving landscape. Use a data-driven lens to think creatively, strategically, and adversarially to identify opportunities.
- Shape the team's roadmap and technical direction. Drive execution, establish strong technical foundations, and mentor junior engineers.
- Partner with Moderation Operations, PM, Data, and stakeholders across Roblox.
- Over 7 years of experience in designing and building deep learning solutions for speech and language modeling. Capable of breaking down product requirements into iterative deliverable stages. Experience in launching computer vision models into production.
- MS or PhD degree in Computer Science, Machine Learning, Speech and Language Modeling, Deep Learning, or a related field.
You are:
- Resourceful: You're adaptable in any situation and can always find a path forward.
- Analytical: Excited to investigate large, ambiguous problems, and quantify the problems and the solutions.
- User Oriented: You always start with the needs of the user, whether they are Roblox users or internal engineers before architecting a solution.
- Team Oriented: You lift up your peers and find ways to make the team stronger. You are a sought-after mentor. You foster a culture of technical excellence.
- Mission Oriented: You stay laser-focused on the mission and are versatile, creative, and strategic to achieve it. You think long-term, and find ways to deliver short-term value on the way to get there.
