Job summary

Twelve Labs is hiring a Senior Backend Software Engineer to build the server-side infrastructure powering our agentic application layer. You will own the transition from prototype to production-ready platform, designing scalable backends for video processing and ML model integration.

Ideal candidates have extensive experience with Python, distributed systems, and cloud-native stacks (AWS/GCP), plus hands-on inference deployment for production ML/CV models. Travel up to 25% to LA is possible.

Qualifications

• 7+ years building production backend systems with a track record of designing scalable web services and APIs.
• 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.

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, audio noise cleaning, and visual analysis.
