Principal Frontend Software Engineer - Discovery

About the Role

Discovery UX sits at the intersection of product innovation and high-scale infrastructure. Every Roblox user starts their journey on the homepage, and every Roblox developer needs to find their correct audience. Our team works closely with product and engineering teams across Roblox to bridge this gap by improving the user journey from landing on Roblox to joining an experience. We primarily work on Home, Search, Charts, and Experience Details pages, for both the Roblox website and app.

As a Principal Software Engineer, you will craft robust, extensible systems for high-traffic surfaces. While you are a frontend expert at heart, you are a versatile engineer who isn't afraid to dive into the backend or data pipelines to ship a complete feature. You will drive solutions using React and modern technologies, helping us build efficiently across devices.

This role reports to the Engineering Manager on the Discovery UX team.

Responsibilities

• Design, build, and ship features that define the discovery journey for millions of users.
• Architect universal solutions for delivering high-performance features across a range of platforms and devices.
• Influence our core client-server orchestration and how we deploy and render code dynamically across the global Roblox ecosystem.
• Drive UX improvements through rigorous A/B testing and deep-dive analysis of experiment results.
• Collaborate with teams across Roblox to ensure a coherent user experience and technical designs that are scalable for long-term success.

Qualifications

• 8+ years of experience in software development.
• 8+ years of experience with web or app technologies (React, TypeScript, JavaScript).
• Proven track record building and launching complex, consumer-facing features.
• Degree or equivalent experience in Computer Science, Applied Math, Physics, Engineering, Statistics, or other technical field is a plus.
