Senior Backend Software Engineer at Twelve Labs building infrastructure for video processing workflows and integrating computer vision models in scalable backend services.
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
Requirements
7+ years building production backend systems with a track record of designing scalable web services and APIs
Experience with video-specific tools and frameworks (FFmpeg, AWS Media Services, transcoding pipelines)
Deep experience with service-oriented architecture, microservices, and distributed systems
Strong proficiency in Python for backend services, model integration, and tooling
Hands-on experience running inference on ML/CV models in production — not research, but engineering models into reliable services
Cloud-native development experience (AWS or GCP), including containerization (Docker, Kubernetes) and serverless patterns
Comfort working across the stack and making pragmatic tradeoffs in a fast-moving product environment

Full health, dental, and vision benefits
