Job Summary:
Weights & Biases is a company that provides a platform for AI innovation. The role involves designing and building workflows and features for researchers to analyze and communicate their experiment results, focusing on frontend development while collaborating across the stack.
Responsibilities:
• Rapidly prototype, iterate, and ship new analysis workflows
• Design frontend experiences in parallel with backend schemas and APIs, evolving data models as user needs become clearer
• Work across the stack to implement end-to-end features, including adding or modifying logging formats, APIs, and data access patterns
• Make pragmatic decisions about how user-logged data should be stored, queried, and rendered to support new analytical questions
• Collaborate closely with product, design, and customer-facing teams to validate ideas early and incorporate real user feedback
• Improve reliability, performance, and scalability when working with large, complex, or high-volume datasets
• Contribute clean, testable, and reusable code; participate in code reviews and help establish patterns that reduce one-off solutions
Qualifications:
Required:
• 4+ years of experience building user-facing software, with a strong focus on frontend development
• Comfortable working across the stack, including backend services, APIs, and data models when product needs require it
• Experience working in ambiguous problem spaces where requirements, schemas, and abstractions evolve over time
• Strong product instincts and ability to reason from user goals to technical design decisions
• Familiarity with modern web technologies such as React, TypeScript, and GraphQL
• Solid understanding of programming fundamentals and experience with at least one backend or systems language (e.g. Go, Python, Java, C++, JavaScript)
• Bias toward action, iteration, and learning through building, with the judgment to avoid over-engineering too early
Preferred:
• Experience designing APIs to support exploratory or analytical workflows
• Familiarity with large-scale data systems, time-series data, media, or domain-specific file formats
• Exposure to 3D point cloud visualization frameworks like BabylonJS and potree
