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.
What You’ll Do:
The CoreUX team is dedicated to making W&B feel like a single, polished product. We drive the evolution of shared building blocks, core user journeys, and universal app surfaces to ensure consistency and accessibility at scale. With a focus on long-term ownership and excellence, the team ensures our application remains fast to build within, easy to use, and impactful across the entire product surface area.
About the role:
As a Senior Software Engineer, you will work in a small but high-impact team of 2–3 engineers. You will drive the development of core UI components, patterns, and behaviors across all product areas, helping to reduce fragmentation and external dependency reliance. In this role, you’ll collaborate closely with other engineers, PMs, and cross-functional stakeholders to align on component APIs, UX consistency, and accessibility best practices (WCAG). You will set and uphold high standards for usability, code quality, and technical excellence, ensuring our "blueprints" enable the wider team to build scalable and user-friendly experiences.
Who You Are
- Experience: You have 5+ years of professional software engineering experience, with at least 3 years deeply focused on modern JavaScript frameworks (specifically React.js).
- Technical Excellence: You are an expert in TypeScript and compon
