Weights & Biases Staff Software Engineer Metrics US

At Weights & Biases, our mission is to build the best tools for AI developers. We founded our company on the insight that while there were excellent tools for developers to build better code, there were no similarly great tools to help ML practitioners build better models. Starting with our first experiment tracking product, we have since expanded our solution into a comprehensive AI developer platform for organizations focused on building their own deep learning models and generative AI applications.

Weights & Biases is a Series C company with $250M in funding and over 200 employees. We proudly serve over 1,000 customers and more than 30 foundation model builders including customers such as OpenAI, NVIDIA, Microsoft, and Toyota.

As a Staff Engineer, you'll lead the effort to scale our metrics and storage systems, ensuring they meet the complex demands of our most advanced customers. You’ll play an instrumental role in the evolution of our platform as we grow our capability to ingest and query petabytes of data, making critical technical decisions that optimize the performance, reliability, and cost-effectiveness of our systems.

You will set the technical direction for the team, guiding the organization to balance short-term deliverables with strategic, long-term architectural improvements. You'll partner closely with product management, revenue teams, and other engineering groups to shape and deliver the future of W&B’s flagship Models product, supporting experiment tracking and analytics utilized by over 2,500 leading machine learning and AI teams worldwide.
