Staff Machine Learning Engineer, Pegasus

📋 Description

• • As a Staff Machine Learning Engineer on the Pegasus team at Twelve Labs Inc., you will drive technical direction for ML engineering while remaining deeply hands-on in critical system design and implementation for the company’s Video Analysis product, which is central to its mission of advancing multimodal foundation models for human-like video understanding.
• • You will own the design and evolution of production ML systems focused on scalability, reliability, performance, and fast iteration; lead technical decisions across model deployment, inference architecture, metadata systems, and ML infrastructure for Video Language Models (VLMs); improve and automate the end-to-end ML lifecycle to accelerate research-to-product translation; mentor engineers; and explore AI-assisted development tools to boost team productivity.
• • The Pegasus team is a core, goal-oriented, cross-functional unit at Twelve Labs responsible for shipping real-world video analysis products, not isolated research, with access to cutting-edge hardware like NVIDIA B300s GPUs and a global presence spanning San Francisco and Seoul, backed by over $110M in funding from top-tier investors including NVIDIA’s NVentures, NEA, and Index Ventures.
• • In this role, you will deepen your expertise in large-scale multimodal ML systems, production ML infrastructure, and AI-assisted development practices while mentoring teammates and shaping the technical foundation of a high-impact AI product used by global B2B customers.
