What are the responsibilities and job description for the Fullstack Engineer, Billing- Weights & Biases position at Weights & Biases?
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.
What You’ll Do
You’ll join the Billing Engineering team, responsible for building and evolving the systems that power how our customers are billed for their usage across AI workloads. This isn’t a space with established playbooks — we’re designing billing systems that fit a new generation of AI products, where no one has fully figured out what “right” looks like yet.
About The Role
This role sits at the intersection of engineering, product design, and the evolving economics of AI. As a Full Stack Engineer on the Billing team, you’ll help create the systems that determine how our customers understand, control, and pay for their usage — a space where thoughtful engineering directly shapes user trust and business value. You’ll design and build end-to-end features across Go and React, collaborating closely with teammates to refine what success looks like as we learn. In a fast-moving field without clear precedents, you’ll have meaningful influence and abundant opportunities to grow.
