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 combining CoreWeave’s world‑class cloud infrastructure with the tools Weights & Biases is best known for, we’re setting a new standard for how AI is built, trained, and scaled.

About The Role

At Weights & Biases, our Platform Engineering organization powers the tools and systems used by ML practitioners to build, train, and scale cutting‑edge models. As Director of Engineering, Platform, you’ll lead a number of mission‑critical teams, driving strategy and execution across four cross‑functional engineering groups, partnering with product, infrastructure, and customer‑facing teams.

The Identity Team – securing the platform through authentication, authorization, and audit capabilities critical to enterprise‑grade ML workflows.

The SDK Team – providing scalable, portable, and developer‑friendly client libraries to integrate seamlessly into training pipelines and ML stacks.

The Billing Engineering Team – ensuring accurate usage metering, entitlement enforcement, and seamless integration with pricing and payment systems.

Your work will enable our product and ML infrastructure teams to move faster, while ensuring reliability, scalability, and security across all layers of the platform.
