Principal Machine Learning Engineer, Content Safety

WHY CONTENT SAFETY?

Safety and Civility is Roblox's #1 priority and our mission is to protect our community. As a Principal Software Engineer on Content Safety, you'll be a hands-on technical leader building systems to ensure that millions of daily user-generated content across Roblox is safe and civil. You’ll work on some of the most challenging problems we face as you drive the transformation of our experience safety efforts into a scale-oriented, near-real-time problem, in an adversarial context. This requires an understanding of code, 3D content, player behavior, and more, working at Roblox scale (billions of engagement hours).

The ideal candidate is creative, flexible across the stack, and a strong hands-on leader who cares about keeping our users safe. Engineering drives the vast majority of the team’s roadmap.

You Will:

• Build end-to-end ML systems to detect and address problematic content on Roblox
• Develop new detection approaches in a rapidly evolving landscape. Use a data-driven lens to think creatively, strategically, and adversarially to identify opportunities. 
• Help define the team's roadmap and technical foundations, and drive execution. Be a technical leader for the team and mentor junior engineers. 
• Partner with Moderation Operations, PM, Data, and stakeholders across Roblox. 

You Have:

• 5+ years of experience building and shipping large-scale ML systems (or parts of these systems) to production
• 5+ years of experience working on multi-person codebases, including open-source or personal projects
• Passion for delivering products end-to-end, from ideation through implementation, with laser focus on the end goal while being empathetic with cross-functional stakeholders.

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.
