About The Position

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 bringing together CoreWeave’s industry-leading cloud infrastructure with the best-in-class tools AI practitioners know and love from Weights & Biases, we’re setting a new standard for how AI is built, trained, and scaled. The integration of our teams and technologies is accelerating our shared mission: to empower developers with the tools and infrastructure they need to push the boundaries of what AI can do. From experiment tracking and model optimization to high-performance training clusters, agent building, and inference at scale, we’re combining forces to serve the full AI lifecycle — all in one seamless platform. Weights & Biases has long been trusted by over 1,500 organizations — including AstraZeneca, Canva, Cohere, OpenAI, Meta, Snowflake, Square,Toyota, and Wayve — to build better models, AI agents and applications. Now, as part of CoreWeave, that impact is amplified across a broader ecosystem of AI innovators, researchers, and enterprises. As we unite under one vision, we’re looking for bold thinkers and agile builders who are excited to shape the future of AI alongside us. If you're passionate about solving complex problems at the intersection of software, hardware, and AI, there's never been a more exciting time to join our team. You'll be joining the Identity team within our Platform organization.

We integrate with multiple OIDC providers and support SSO across diverse deployment models. We support both our multi-tenant environment to both managed and on-premise single-tenant environments serving customers with varying identity provider requirements. As a Software Engineer II on the Identity team, you'll play a key role in evolving our identity infrastructure to meet the needs of our growing customer base. You'll spend your time building new product features, contributing to the restructuring of our identity systems into a dedicated service, and implementing critical security capabilities. Your day-to-day work will involve working on role-based access controls (RBAC), SCIM integrations, service account functionality, and supporting multiple deployment environments. This is primarily a backend-focused role (80% Go, 20% TypeScript/React) where you'll work across our multi-tenant and single-tenant architectures, occasionally helping debug customer issues across AWS, GCP, and Azure environments.
