Director of Engineering, Platform – Weights & Biases

CoreWeave, the AI Hyperscaler™, acquired Weights & Biases to create the most powerful end-to-end platform for developing, deploying, and iterating AI faster. Since 2017, CoreWeave has operated a growing footprint of data centers across the US and Europe and was ranked as one of the TIME100 most influential companies of 2024. By combining CoreWeave's cloud infrastructure with the best-in-class AI tools from Weights & Biases, we're setting a new standard for how AI is built, trained, and scaled.

Our integration accelerates a 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 serving 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. As part of CoreWeave, that impact is amplified across a broader ecosystem of AI innovators, researchers, and enterprises.

We're looking for bold thinkers and agile builders excited to shape the future of AI. If you're passionate about solving complex problems at the intersection of software, hardware, and AI, now is the time to join our team.
