Rumble is the Freedom-First technology platform. We proudly offer a video platform, cloud services, advertising solutions, and a non-custodial cryptocurrency wallet.
Rumble is seeking a Senior Back-End Developer to design, build, and maintain high-performance server-side systems that power a large-scale video platform serving millions of users. This is a senior individual contributor role for someone who can own backend systems end to end, improve them in production, and make strong technical decisions as scale, complexity, and performance demands grow.
Our environment centers on backend services, data-intensive application logic, and production systems that must perform reliably at high scale. You should be comfortable working across PHP, MySQL, caching layers, APIs, Linux environments, and legacy systems, while also partnering effectively with front-end engineers to connect user-facing components to server-side logic.
You'll work closely with engineering partners to turn requirements into clear technical plans, apply strong systems design fundamentals to complex backend problems, and make sound implementation decisions across application, data, and infrastructure layers.
ResponsibilitiesDesign and evolve scalable backend systems for a high-traffic video platform, with a focus on performance, maintainability, and long-term reliability. This includes building APIs, optimizing MySQL schemas and queries, implementing effective caching strategies with Memcached and Redis, and supporting background jobs or data-processing workloads that operate at significant scale.
The role also includes maintaining and modernizing legacy code, integrating front-end components with backend logic, and contributing to technical direction through code reviews, reusable patterns, and sound architectural judgment.
Qualifications- 8+ years of experience in back-end development, including strong experience building production systems at scale.
- 10+ years of experience with object-oriented programming languages, including 5+ years working with PHP and modern PHP practices such as PHP 8+.
- Strong experience with MySQL, including schema design, indexing, and query optimization, along with hands-on experience using caching systems such as Memcached and Redis.
- In-depth understanding of web development fundamentals, protocols, and Linux server environments, including reading logs and troubleshooting production issues.
- Working knowledge of front-end technologies such as JavaScript or TypeScript, HTML, and CSS, along with the willingness to jump into any project when needed.
- Experience with video technologies, containers, codecs, or live streaming environments.
- Experience with NGINX, WebSocket-based communication, BASH scripting, networking fundamentals, or static analysis tools such as PHPStan.
- Degree in Computer Science, Engineering, or a related field.
- Experience modernizing legacy PHP applications, working with server-side rendering architectures, or contributing to CI/CD and automated testing practices such as PHPUnit.
