Openlayer is a testing and debugging platform for machine learning models. Openlayer makes it easy for ML teams to find failures and biases, figure out their root causes, and create unit tests to ensure they stay fixed — all baked in with experiment tracking and versioning (think GitHub for ML). The company was founded by three previous Siri engineers who contributed to over 15 different AI/ML projects at Apple.

Openlayer is currently working with several well-known enterprise companies worth over $1B, helping them rapidly improve the quality of their models and datasets and save tons of time and money.

We're looking for a founding engineer to help us build the future of sustainable, performant, and ethical machine learning.

We're backed by Y Combinator and several of the top investors and funds in the world, including the founders of companies like Instagram, Voyage, Instacart, Sendbird, Mercury.
