About The Position

CoreWeave, the AI Hyperscaler™, acquired Weights & Biases to create the most powerful end-to-end platform to develop, deploy, and iterate AI faster. Since 2017, CoreWeave has operated a growing footprint of data centers covering every region of the US and across Europe, and was ranked as one of the TIME100 most influential companies of 2024. By bringing together CoreWeave’s industry-leading cloud infrastructure with the best-in-class tools AI practitioners know and love from Weights & Biases, we’re setting a new standard for how AI is built, trained, and scaled. The integration of our teams and technologies is accelerating our shared mission: to empower developers with the tools and infrastructure they need to push the boundaries of what AI can do. From experiment tracking and model optimization to high-performance training clusters, agent building, and inference at scale, we’re combining forces to serve the full AI lifecycle — all in one seamless platform. Weights & Biases has long been trusted by over 1,500 organizations — including AstraZeneca, Canva, Cohere, OpenAI, Meta, Snowflake, Square,Toyota, and Wayve — to build better models, AI agents and applications. Now, as part of CoreWeave, that impact is amplified across a broader ecosystem of AI innovators, researchers, and enterprises. As we unite under one vision, we’re looking for bold thinkers and agile builders who are excited to shape the future of AI alongside us. If you're passionate about solving complex problems at the intersection of software, hardware, and AI, there's never been a more exciting time to join our team. Reporting to the Engineering Manager for Workspaces, you’ll join a collaborative team responsible for delivering end-to-end product features within our Models product—the central hub for experiment tracking and visualization. Thousands of Machine Learning Engineers rely on our tools every day to monitor and understand their ML training runs. To see the kind of work you’ll contribute to, check out an example workspace or try our tutorial. The Colab notebook requires no prior ML experience to run, and we’re proud of how easy it is to get started. This role sits within our Models Engineering organization, where we focus on building features that streamline and centralize the machine learning development workflow. As a Product Software Engineer, you’ll work directly with customers and cross-functional teams to build experiences that accelerate ML model development.
