Company mission
To build the best video understanding platform driven by leading perceptual-reasoning research
Role
Who you are
- 5-7 years of experience building and scaling production web applications
- Strong expertise in Node.js backend development and API design
- Experience with database design, query optimization, and data modeling at scale
- Track record of building asynchronous job processing systems and handling long-running operations
- Experience with cloud infrastructure (AWS/GCP) and CDN configuration
- Proven ability to architect systems that scale from hundreds to thousands of users
Desirable
- Deep experience with video processing (FFmpeg, transcoding, streaming protocols)
- Background in AI/ML product development or computer vision applications
- Experience with video editing workflows, media asset management, or creative tools
- Familiarity with export formats (EDL, FCPXML) and professional video standards
- Track record of migrating client-heavy applications to scalable server architectures
What the job involves
- We're looking for a Fullstack Engineer to architect and build the infrastructure that powers AI-driven video workflows at scale. You'll join a small, high-impact team and own the critical transition from prototype to production-ready platform
- Design and implement scalable backend architecture using Next.js API routes and Node.js
- Build robust video processing pipelines for ingestion, transcoding, and multi-format exports
- Create background job systems for long-running video operations with proper queuing and error handling
- Architecting data models and database schemas that support collaborative video editing at scale
- Implementing authentication, authorization, and session management systems
- Optimizing video storage and CDN delivery for thousands of concurrent users
Our take
Developing an algorithm that can understand text or images is (relatively) straightforward. However, the challenge escalates when it comes to understanding video, where these modes merge with audio, and context becomes much harder to grasp.
Twelve Labs has developed a machine learning solution that tackles this challenge by making the inner content of videos both indexable for developers and highly searchable for users. This technology could prove immensely valuable, with use cases extending far beyond simple searchability for end users. It could be employed for more accurate monitoring of community guidelines on social media, enterprise knowledge searches, and a deeper understanding of the value of video content.
With recent funding under its belt, Twelve Labs is set for rapid growth. The investment will drive R&D, nearly double its workforce, and advance its video understanding technology. As it expands, Twelve Labs is well-positioned to lead the future of multimodal AI and revolutionize how organizations extract values from video content.
