What are the responsibilities and job description for the Senior Front-End Engineer, Rumble.com position at Rumble?
Join our team at Rumble.com and help build web experiences that are fast, beautiful, and seamless! We're looking for a Senior Front-End Engineer who loves crafting user-friendly, responsive, and dynamic web applications. If you're passionate about clean code, great design, and creating interfaces that users love, let's talk.
What You'll Do:
- Create engaging, responsive interfaces with Solid.js, TypeScript, vanilla JavaScript, and Tailwind CSS (or good old traditional CSS).
- Design and build modular, reusable components for a scalable front end that works beautifully on mobile, tablet, and desktop.
- Work your magic with APIs (REST, GraphQL, WebSockets, SSE) to fetch, display, and dynamically update data in real time.
- Optimize web performance by writing efficient JavaScript and CSS, improving load times, and reducing file sizes.
- Bring our UX/UI designs to life by collaborating with designers and back-end engineers to ensure a seamless experience.
- Write clean, well-tested code and partner with QA to squash bugs and keep things running smoothly.
- Improve SEO by making sure our web apps are technically optimized (think metadata, structured data, and more).
- Contribute to everything from code reviews to brainstorming better processes and practices.
What We're Looking For:
- 10 years of software development experience, with expertise in front-end engineering and architecture.
- Mastery of JavaScript — you’re comfortable with ES6 features, closures, async programming, and DOM manipulation.
- Hands-on experience with several different front-end frameworks (e.g., Solid.js, Vue.js, React.js) and vanilla JavaScript.
- Proficiency in responsive design using CSS, Flexbox, and Grid, with layouts that adapt seamlessly to all screen sizes.
- Experience building cross-browser-compatible interfaces that work flawlessly in Chrome, Firefox, Safari, Edge, etc.
- Familiarity with handling HTTP requests, APIs, and authentication methods.
- A focus on performance — whether it’s optimizing for speed, reducing latency, or improving scalability.
- Solid experience with Git for version control.
- Ability to manage the full development workflow, from gathering and clarifying requirements to implementation, testing, and successful deployment.
Bonus Points for:
- Experience with tools like Rollup, Webpack, Vite, SSR/SSG approaches, and micro-frontend architectures.
- Skills in visualizing large datasets with libraries like D3.js or Chart.js.
- Comfort working with real-time technologies like WebSockets and live data streams.
- Familiarity with testing frameworks like Jest, Mocha, Cypress, or Selenium.
- Back-end knowledge in PHP, Go, or other server-side languages.
- Experience working with video technologies (HTML5 , codecs, streaming).
Extra Credit If You:
- Have worked with headless browser tools like Puppeteer, Playwright, or Selenium.
- Understand the nitty-gritty of networking concepts (HTTP, WebSocket, DNS, CDN).
- Have a strong sense of UI/UX design and love creating intuitive interfaces.
We’re excited about pushing the limits of what web apps can do, and we’d love for you to bring your skills, creativity, and ideas to the team. Let’s build something amazing together!
