However, becoming proficient and gaining job-ready experience typically requires ongoing practice and real-world project work beyond this timeframe.

What does a JavaScript Backend Developer do?

A JavaScript Backend Developer is responsible for building and maintaining the server-side logic, databases, and APIs that power web applications. They use JavaScript, often with frameworks like Node.js, to process requests, manage data, and ensure smooth communication between the frontend and backend of an application. Their work ensures that web applications are scalable, secure, and efficient. JavaScript Backend Developers also collaborate with frontend developers and other team members to deliver seamless user experiences.

What are the key skills and qualifications needed to thrive as a Javascript Backend Developer, and why are they important?

To thrive as a Javascript Backend Developer, you need strong proficiency in JavaScript (especially Node.js), knowledge of backend frameworks, and a solid understanding of databases such as MongoDB or PostgreSQL. Familiarity with development tools like Git, RESTful APIs, Docker, and cloud platforms, as well as relevant certifications, is highly valuable. Excellent problem-solving, teamwork, and communication skills help you collaborate effectively and deliver robust solutions. These abilities are crucial for building scalable, secure, and maintainable backend services that power modern applications.

What is JavaScript salary?

Entry-level positions may start lower, while senior roles can exceed $150,000.

What are the typical challenges a JavaScript Backend Developer faces when scaling applications for high traffic?

JavaScript Backend Developers, especially those working with Node.js, often encounter challenges related to handling high concurrency, optimizing database queries, and maintaining application performance under heavy load. Ensuring efficient memory management and implementing robust error handling are also critical when scaling. Working closely with DevOps and frontend teams to optimize APIs and monitor system health is essential for delivering reliable, scalable backend solutions.

Job description

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.

Responsibilities

Design 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, HTTP 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.
Preferred Qualifications
  • 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.
Annual Compensation Range

$159,000 - $176,000 USD base + benefits + equity

Note: The salary range listed for this position is a good faith estimate based on experience, qualifications, and internal compensation structure. The actual salary offered varies depending on the candidate's skill level and experience. This posting refers to an active vacancy within the organization.
