Senior Software Engineer, Frontend

Job Description

In this Senior Frontend Engineering role, you will be a key contributor in shaping the future of Roblox’s application surfaces. You will develop the architecture and technical direction of our frontend stack for consumer-facing surfaces, working across teams and technology platforms to ensure our solutions are universal and scalable.

Responsibilities

• Develop the architecture and technical direction of our frontend stack for consumer-facing surfaces, working across teams and technology platforms to ensure our solutions are universal and scalable.
• Define how all our frontend pieces fit together, how data flows through the client, and how we can build features faster and more reliably.
• Work with modern frameworks and also dive into our custom Luau-based tech, bridging the best ideas from the web ecosystem into Roblox’s unique environment.
• Create reusable frontend abstractions using React paradigms and modern tech to enable fast, consistent UI development across teams and devices.
• Maintain and evolve Roblox’s internal React-inspired Luau UI libraries, promoting modular design, state management patterns, and performance.
• Define architecture standards to ensure frontend code is scalable, testable, and aligned with proven patterns like Flux, MVC, and MVVM.
• Partner with engineering, product, and design teams to integrate shared solutions and deliver cohesive, high-quality user experiences.
• Address cross-surface issues like memory, responsiveness, and load times to ensure a reliable, fast UI at scale.
• Provide architectural leadership, review designs/code, and mentor engineers in best practices and effective use of platform tools.

Requirements

• Bachelor’s degree in Computer Science or a related field, or equivalent practical experience.
• 8+ years of software development experience, including substantial experience building user-facing frontend applications.
• Proven track record in implementing or architecting complex frontend systems for large-scale applications (experience with large-scale or high-traffic applications is a plus).
• Deep expertise in modern mobile/web/frontend technologies – including proficiency in HTML5, CSS3, and JavaScript/TypeScript or mobile equivalents – and hands-on experience with frameworks such as React.
• Comfortable with component-based architecture and state management patterns (Redux/Flux or similar) for building maintainable UIs.
• Strong programming skills in one or more scripting languages relevant to frontend and tooling such as TypeScript, Swift or Kotlin, or the ability to quickly learn them, is highly desirable.
• Solid understanding of software design principles and architectural patterns as they apply to frontend development.
• Able to design clean APIs and module boundaries, and experienced in creating maintainable and testable code bases with proper unit/integration testing practices.
• Demonstrated ability to optimize frontend performance and diagnose issues.
• Knowledge of performance debugging, profiling, and benchmarking techniques on the client side.
• Passion for ensuring fast, fluid user experiences on all devices.
• Excellent communication skills and a team-oriented mindset. Ability to work effectively with cross-functional teams, gather requirements, and drive consensus on technical solutions.
• Ability to share ideas, document designs, and collaborate in a large engineering organization.
• Experience developing applications or libraries across multiple platforms (web, mobile, desktop).
• Familiarity with building applications that serve users on Web, iOS, Android, Windows, etc. is desirable for ensuring a seamless cross-platform experience.
• Familiarity with C++ or other low-level languages is a nice to have but not mandatory.
