Why join us?

    • Researchers at OpenAI, Toyota Research Institute, Lyft and other top-tier institutions use and love our current product
    • We have extensive experience working with companies to turn machine learning research projects into scalable, real-world deployments. We’ve watched hundreds of teams struggle to deploy machine learning models successfully, and the same problems show up repeatedly. Machine learning has created a fundamentally new kind of programming, requiring a fundamentally new set of developer tools. We created Weights & Biases to provide that missing toolkit.
    • We have an experienced founding team including the founders of CrowdFlower (now Figure Eight), a successful startup in the machine learning space
    • Here's a quote from Wojciech Zaremba, Cofounder and Robotics Lead, OpenAI: "W&B allows to scale up insights from a single researcher to the entire team, and from a single machine to hundreds of them."
    • Our stack: React, Typescript, GraphQL, Python, Golang, Kubernetes, Google Cloud Platform
We care about diversity and are seeking people who love to learn and collaborate in an inclusive environment. We are an equal opportunity employer and do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
