Job description

Context: Trajectory is building the platform for continual learning: a creative tool for model development that makes it easy for any AI company to build and train its own custom models. We're aiming for a public GA launch at the end of October.

The ask: Help us with the last 20% of visual polish, so the platform feels like a best-in-class developer tool. Our flows and page structure are in place; we need a designer to make it look and feel finished.

The work:

• Audit every page of the platform and propose + create fixes for visual nits

• Tighten the visual system: type, color, spacing, iconography, component states

• Polish layout and page construction: navigation, page headers, tables, charts, empty states

• Work with our design engineering and product team to set the visual direction for core primitives, such as how models, training runs, checkpoints, and trajectories are represented

Who we're looking for:

• A visual / systems designer with a portfolio of dense B2B or developer tools

• Either works in Figma or comfortable vibe coding visual iterations directly on our platform

• Not responsible for production PRs or merging these into the product

Products we admire: Stripe, Linear, Vercel, Braintrust, Supabase, Modal, Figma, and Notion.
