Senior Backend Engineer

Twelve Labs is pioneering the development of cutting-edge multimodal foundation models that understand videos like humans. As a Senior Backend Software Engineer, you will build server-side infrastructure for video processing workflows and collaborate with a high-impact team to transition from prototype to production-ready platform.

Responsibilities:

• Design and build backend services for video processing workflows — ingestion, transcoding, 4K export, metadata extraction, and timeline operations
• Architect scalable, high-availability systems to support enterprise-grade video workloads across cloud-native infrastructure (AWS, GCP)
• Build and optimize APIs that power real-time and async frontend workflows, including streaming data delivery and long-running job orchestration
• Own performance and reliability for distributed video processing pipelines with low latency and high throughput requirements
• Collaborate closely with frontend engineers on API design, data models, and streaming strategies
• Integrate and run inference on computer vision models for tasks like video resizing, scene detection, automatic audio noise cleaning, and visual analysis
• Deploy and serve ML models on cloud-based or cloud-native platforms — evaluate build-vs-buy for model serving and SaaS alternatives
• Work with the research team to productionize model outputs into reliable, scalable backend services
• Build pipelines that bridge TwelveLabs’ foundation models with third-party CV models to power intelligent video workflows
