Multimodal Infrastructure

Full Job Description

Design, develop and maintain large-scale multimodal data processing pipelines. Design, develop and maintain large-scale multimodal model pretraining and post-training frameworks. Design, develop and maintain large-scale multimodal model inference and serving frameworks. Work with research scientists and product engineers to solve infra-related problems. Find a path to get things done despite roadblocks to get your work into the hands of users quickly and iteratively. Enjoy working in a fast-paced, design-driven, product development cycle. Embody our Culture and Values.
