About the Role:
We're looking for a talented and experienced Senior Backend Engineer to lead the development and scaling of our Media Service. This is a critical role within our engineering team, as you will be responsible for building the infrastructure that handles all user-generated content (images and videos) on our social platform. You are passionate about building high-performance, scalable, and reliable systems, and you thrive in a fast-paced, collaborative environment. You're comfortable owning a complex service and working independently.
Responsibilities:
Design, develop, and maintain our Media Service using Node.js and TypeScript.
Implement efficient and scalable solutions for image and video processing (resizing, transcoding, format conversion).
Integrate with Content Delivery Networks (CDNs), primarily CloudFront.
Optimize storage and retrieval of media assets using AWS S3 (and potentially other storage solutions).
Implement content moderation techniques (potentially integrating with third-party services).
Ensure the reliability and security of the Media Service.
Write unit, integration, and end-to-end tests.
Participate in code reviews and contribute to best practices.
Work closely with other backend engineers and frontend engineers.
Proactively identify and address performance bottlenecks.
Stay up-to-date with the latest trends in media processing and delivery.
Contribute to architectural decisions and help shape the technical direction of the Media Service.
Understand the end-to-end flow of our application, especially as it relates to media.
Think customer-centrically, ensuring a smooth and fast media experience for users.
Qualifications:
5+ years of experience in backend development, with a strong emphasis on Node.js and TypeScript.
Proven experience building and scaling media-heavy consumer applications. This is the most critical qualification.
Experience with image and video processing libraries.
Experience with Content Delivery Networks (CDNs).
Experience with cloud storage solutions (e.g., AWS S3).
Strong understanding of RESTful API design.
Experience with databases (MongoDB, PostgreSQL).
Experience with testing frameworks.
Excellent problem-solving and communication skills.
Ability to work independently and take ownership of projects.
Bonus Points:
Experience with content moderation tools and techniques.
Experience with streaming video.
