Senior Software Engineer, Consumer Apps

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 were 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. Were 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 youll 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.

Most engineering roles own one area. On the Consumer Apps team youll make an impact across every surface of the Roblox app. We build the shared platform that Robloxs user interface runs on including the component library server-driven UI the core app frame and navigation and the frameworks underneath them all. When we get it right people feel it every time they open the app and every product team ships faster. Recently we shipped app-wide themes including an anniversary Classic theme and a Halloween theme that changed how Roblox looks and feels across every surface at once.

Were looking for a Senior Software Engineer who thinks beyond the usual playbook: someone who questions how things are done works with AI agents as a natural part of how they build and moves fast with good judgment about what matters to the people using our product.

• Make an impact across every surface of the app building the frameworks APIs and systems that product teams across Roblox build on and shipping cross-app capabilities like app-wide theming that change the whole app at once
• Build and evolve the core systems beneath the UI such as navigation routing state management and data flow so features load quickly and behave consistently
• Drive app performance transition smoothness and layout stability across phones tablets and desktop using traces and telemetry to set measurable quality bars
• Roll out platform changes safely at scale using feature flags staged rollouts and side-by-side validation of old and new implementations with fast rollback when needed
• Drive adoption of the platform across Roblox by partnering with product design and feature engineering teams to guide them onto our frameworks and components and turning their feedback into a better platform
• Use AI agents and automation to move faster and help shape how our team and our partner teams build with them
• Raise the quality bar through thoughtful code review strong test coverage and clear documentation and mentor other engineers

• 4 years of professional experience building and shipping client applications ideally on mobile (iOS Android) or desktop with a strong foundation in application architecture
• Hands-on experience with React or React Native with enough depth to reason about how components state and rendering behave and the curiosity to pick up frameworks and tools that are new to you
• Experience designing shared frameworks UI platforms or core libraries that other engineers build on
• Strong debugging and profiling skills with experience diagnosing client performance issues such as slow startup visual stutter and memory pressure across screen sizes and form factors
• Comfort working in a large evolving codebase including migrating legacy code incrementally using feature flags and staged rollouts
• An agentic mindset and fluency with AI coding tools: you look for ways to automate delegate and structure work so that both people and agents can do it well
• Strong written and verbal communication skills and the ability to align multiple teams around a technical plan

• Someone who challenges the status quo asks why we do things the way we do and proposes better options
• A creative outside-the-box thinker who looks for the approach nobody has tried yet
• Someone who moves fast and is comfortable shipping boldly and when something breaks diagnoses it fixes it and learns from it quickly
• Someone with an eye for product who cares how what you build feels to the people using it
• A candid constructive voice who gives clear feedback to engineers designers and product partners and takes it well in return

• Experience with Luau or Lua
• Experience with React Navigation or comparable routing libraries
• Experience with native mobile development on iOS or Android
• Experience with server-driven UI or dynamic UI delivery systems
• Experience building cross-platform applications that run on mobile desktop and console
• Experience supporting other engineers in adopting a shared platform through documentation migration guides or direct developer support
