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.

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.

Minimum Qualifications

• 5+ years of experience building and maintaining production web applications, with strong competency across both backend and frontend systems.
• Deeply comfortable working in evolving or ambiguous systems, using pragmatic decision-making to drive progress without unnecessary rework or premature abstraction.
• Experienced with Go, React, or similar technologies, and proficient in designing clean interfaces between services, databases, and UI flows.
• Skilled at evaluating performance, reliability, and operational cost — determining when improvements materially change outcomes and when simpler solutions suffice.
• Strong communicator who collaborates effectively across teams, clarifies requirements, articulates tradeoffs, and helps align partners with different priorities.

The base pay and target total cash for this position range from $182,000 to $242,000. The starting salary will be determined based on job-related knowledge, skills, experience, and market location. We strive for both market alignment and internal equity when determining compensation. In addition to base salary, our total rewards package includes a discretionary bonus, equity awards, and a comprehensive benefits program (all based on eligibility)

What We Offer The range we’ve posted represents the typical compensation range for this role. To determine actual compensation, we review the market rate for each candidate which can include a variety of factors. These include qualifications, experience, interview performance, and location.
