About the role
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.
As Weights & Biases and CoreWeave unite to deliver the most powerful AI development platform, the Customer Support Engineer (Tier 3) plays a pivotal role in ensuring our most complex and business-critical issues are resolved quickly and effectively.
This role serves as the bridge between Support and Engineering, diving deep into escalated technical challenges, identifying root causes, and partnering closely with engineering teams to ensure long-term fixes and improvements. Your work enables our engineers to stay focused on building and scaling the platform while ensuring our customers receive the highest level of technical care.
