What you ll do

• Build the React dashboards publishers and internal teams use: ad unit management, monitoring, reporting, and operational workflows.
• Turn product direction into finished UI: layout, components, and loading, empty, and error states.
• Own how those screens feel: component structure, state, responsive layout, accessibility, and performance on data-heavy pages.
• Connect those screens to existing APIs (ad networks, mediation, reporting) and shape the data on the client.
• Ship a feature from the React screen through the Go service and the MySQL, PostgreSQL, or MongoDB data behind it, working with senior engineers.
• Debug UI issues and make the product faster and more reliable for the people using it.

What we re looking for

• Strong React: components, hooks, and state.
• Solid HTML, CSS, and JavaScript or TypeScript.
• Comfortable building tables, filters, charts, and dashboards.
• Able to read an API and wire it into the UI.
• Working knowledge of Go for the services behind those screens.
• Familiarity with MySQL or PostgreSQL, and MongoDB.
• Care about how a screen looks and behaves.
• A builder s mindset in a fast-moving environment.

Bonus points

• Design systems or component libraries.
• Dashboard or charting work.
• ClickHouse or BigQuery.
• Freelance projects or startup experience.
• Experience building MCP (Model Context Protocol) servers.

What makes you a great fit

• You think in screens, flows, and the task a publisher is trying to finish.
• You write clear React and sweat the details people actually feel.
• You re comfortable in Go and the databases the product already uses, and you ll step into the API when the UI needs something that isn t there yet.
• You explain tradeoffs clearly and work well with product and engineering.
• You like a fast-paced startup and care about the quality of what ships.
