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.
About this Role:
As a Senior Software Engineer on the Billing team, focused on full stack development, you’ll work at the intersection of engineering, product design, and the evolving economics of AI. Billing at W&B and CoreWeave spans the entire product surface — usage metering, cost transparency, customer experience, internal tooling — and touches nearly every team. In this role, your engineering judgment will influence not only how we build billing systems, but how we coordinate across teams, design shared interfaces, and evolve our product in a fast-changing industry.
We operate in a high-growth environment where clarity, flexibility, and thoughtful decision-making matter. Engineers on this team support each other in shaping direction, opening doors with stakeholders, and driving meaningful improvements across the organization. If you enjoy turning ambiguous problems into elegant solutions and want the opportunity to influence both product direction and engineering practices at scale, this role offers that rare combination.
What You’ll Do
- Lead end-to-end development across our Go services and React applications, shaping systems that must balance correctness, flexibility, and usability for customers and internal teams.
- Bring clarity to evolving problem spaces by identifying constraints, defining practical boundaries, and aligning cross-functional partners early and often.
- Evaluate technical debt and existing system b
