AI for the Physical World. 

At Ramblr, we build vision AI agents that understand work as it happens. Grounded in a company’s knowledge, processes, and operational context, our agents recognize real-world situations from egocentric video and other signals, guide operators through complex tasks, verify quality and compliance, and support service and maintenance teams at the point of work.

Ramblr One, our developer platform for physical AI agents, is the foundation for all of this: a data engine that structures video, images, manuals, and expert knowledge into activities, relations, and skills, plus an agent studio to build, evaluate, deploy, and monitor agents on our or the customer's infrastructure, with no model lock-in. Our customers range from industrial leaders to robotics teams closing the gap between data and physical AI.

Job Description

We are looking for a strong Machine Learning/AI Engineer to deploy and maintain state-of-the-art models and embed them in production systems that combine vision-language models, computer vision, and agentic components. You write clean, efficient, and highly parallelized code to improve and extend our physical AI stack, and you help make building and deploying new features on Ramblr One faster and more reliable.

Drawing on your understanding of modern deep neural networks and agentic systems, you take responsibility for the performance and reliability of our platform. You build and optimize parts of our AI stack and integrate them efficiently into our products.
