About this role

• You will own the frontend architecture of the W&B app, the product ML researchers and engineers work in every day, and be accountable for app performance, stability and reliability
• A single page in W&B assembles data from many parts of the product, which power different product features owned by different teams
• Individually those requests are all reasonable; in aggregate they contribute to increased load times and a worse experience for users

• In this role you’ll be responsible for the architecture, performance, and stability of the W&B Models frontend, defining the frontier of innovation for the team, and managing cross team requirements within the Models system
• Some examples of what you’ll do:
• Setting performance targets and driving the work that meets them, with results proven in production data
• Deciding the app’s delivery and rendering architecture, including how code is delivered efficiently
• Partnering with backend and platform teams on API design, including moving work out of the client
• Proposing and driving the larger overhauls that incremental work cannot reach
• Investing in our people is one of our top priorities, and we value candidates who can bring their diversified experiences to our teams
• Here are some qualities we’ve found compatible with our team
• We’d love to talk about whether this aligns with your experience and interests and what you’re excited to work on next- Have led the transformation of a large, long-lived React application with ...
