Rumble is a high-growth neutral video platform that is creating the rails and independent infrastructure designed to be immune to cancel culture. Rumble’s mission is to restore the Internet to its roots by making it free and open once again.

Rumble Studio is seeking an experienced Front-End Engineer to lead the development of our real-time collaborative web application that enables creators to live stream directly from the browser using WebRTC technology. You'll work with modern frameworks like Next.js, React, and TypeScript while building seamless real-time experiences.

Job Responsibilities:

• Develop clean, efficient, and scalable front-end code for our real-time collaborative live streaming platform using Next.js, React, and TypeScript. Write code that handles complex real-time state management, WebRTC connections, and live media streams while maintaining performance and minimizing technical debt.


• Design and implement user interfaces that seamlessly consume data from our GraphQL API. Collaborate with backend teams to align on API contracts, optimize data fetching strategies, and ensure the front-end experience is performant and reliable.


• Own the full lifecycle of features—from early concept and technical design to


• implementation, testing, launch, and post-launch maintenance. Ensure designs are responsive, accessible, and user-friendly across devices.


• Troubleshoot and debug complex front-end issues that may span across the client layer, WebRTC connections, GraphQL queries, or browser-specific behaviors. Quickly isolate and resolve problems in real-time streaming scenarios, ensuring minimal disruption to live broadcasts.


• Collaborate cross-functionally with backend developers, designers, product managers, and QA engineers to ensure seamless integration between the front end and back end, high code quality, and timely delivery of real-time features that power our live streaming platform.


• Translate user and business needs into technical solutions. Break down complex UI features and performance issues into manageable tasks. Work closely with product and design to ensure the implementation matches intent and enhances user experience.


• Continuously assess and refactor the codebase, identifying areas for improvement in performance, structure, and maintainability. Propose architectural enhancements and design patterns that promote long-term scalability of the front-end application.

Requirements:

• Strong experience writing clean, maintainable, and well-documented code with JavaScript and TypeScript


• Professional experience using React and Next.js to build production-grade web applications

• Strong problem-solving skills with the ability to turn ambiguous product needs into clear, executable UI solutions


• Familiarity with authentication protocols such as OAuth2 or OpenID Connect and their front-end implementations

Desired Qualifications:

• Ability to optimize complex UIs for performance, understanding browser internals, rendering bottlenecks, and memory usage


• Experience building applications that gracefully handle network latency and intermittent connectivity


• Exposure to server-side rendering (SSR), incremental static regeneration (ISR), and other Next.js data fetching strategies


• Comfortable working with cross-browser and responsive design challenges


• Knowledge of media streaming protocols and standards beyond WebRTC (HLS, DASH, etc.)
