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.
