Job description

The product earns trust the moment someone can see a protocol’s power structure at a glance. You will build that: the interactive node graph, the permissions view that de-anonymizes who holds control, and the dashboard around them, in a modern React and TypeScript stack.

What you'll do

• Build and own the product UI: the node map, permissions views, and evaluation dashboard.
• Turn dense on-chain data into interfaces an allocator can read at a glance.
• Work closely with design and research to ship from prototype to production.
• Keep the front end fast, accessible, and maintainable as the product grows.

What we're looking for

• Strong React and TypeScript, with an eye for detail in the rendered result.
• Experience building data-dense interfaces: graphs, tables, and interactive visualizations.
• Comfort owning features end to end, from design hand-off to shipped product.
• Care for performance and accessibility, not as an afterthought.

Nice to have

• Experience with data-viz libraries such as D3, visx, or node-graph tooling.
• Familiarity with crypto, on-chain data, or security tooling.
