At Weights & Biases our mission is to build the best tools for machine learning. Our experienced technical cofounders built Figure Eight, and our tools are being used by cutting-edge machine learning teams including OpenAI and Toyota. We're looking for passionate, driven people who love to learn and collaborate in an inclusive work environment.


We're building a culture where people love coming to work to build cool things and collaborate with other smart people. It’s important to us that everyone feels comfortable being themselves and being honest with each other, and all of us take responsibility for making our customers successful. We love to work with people who are driven, kind and proactive. We care about diversity and if you are part of an underrepresented minority, we especially encourage you to apply to work here.

We are contributing to responsible AI with tools for transparency and reproducibility in model development and deployment.


As second time founders, our company is small but well funded by top tier investors. We offer market salary, benefits and equity comparable to a Series C startup. When we're not all working from home, our sunny, pet-friendly office is located in the SOMA district of San Francisco.
