  • Outcome-drivenWant to build frontend systems that directly impact revenue - not just ship UI components that nobody uses?

This is not a typical frontend role where you move pixels around, close Jira tickets, and disappear into the design backlog.

You’ll build the web application and experiment engine that our Monetization and Business teams rely on daily to manage a portfolio of millions of users. You will see the impact of your UI decisions fast.

Now we’re building an internal platform that powers our monetization engine - and we’re looking for a frontend engineer who can own the entire user experience behind it.

About BlueThroneBlueThrone is a remote-first company scaling a portfolio of mobile apps across multiple markets and categories.

We combine product intuition, growth execution, and sharp monetization strategy - and we double down on what works.

We’re not a corporate org with layers and slow approvals. We operate like a lean, high-ownership team where strong execution matters more than fancy titles.

Our teams work closely across product, growth, monetization, and engineering - and we care about one thing: building things that move the needle.

The roleYou’ll join a lean, horizontal team building our internal revenue optimization platform.

Your mission: Build and own the web application that serves as the mission control for our monetization efforts. From complex experiment configurations to high-performance analytics dashboards, you will create the tools that allow our team to move faster and scale winning strategies across our app portfolio.

You’ll be making core architectural decisions, shaping API contracts with the backend team, and ensuring our internal tooling is as polished and intuitive as a consumer product.

What You'll Do

  • Build and own the web app for our monetization and experiments platform.
  • Refine and implement complex experiment configuration interfaces (parameter configs, audience segmentation, etc.).
  • Build analytics dashboards and data visualizations that turn raw numbers into actionable insights.
  • Build platform admin tooling to streamline operations.
  • Work closely with Monetization and Business teams to translate requirements and prototypes into intuitive, high-performance UI.
  • Shape API contracts together with backend engineers to ensure seamless data flow.
  • Own frontend architecture and component design, ensuring a scalable and maintainable codebase.

What We're Looking For

  • 5+ years of commercial frontend development experience.
  • Expertise in React and modern JavaScript/TypeScript.
  • Strong proficiency in TypeScript, CSS, and HTML - you write clean, type-safe, and performant code.
  • Proven track record of building complex, data-rich web applications.
  • Solid understanding of state management for non-trivial business logic (Redux, Zustand, React Query, etc.).
  • Eye for UI/UX - you care about how things look and feel, not just that they work.
  • Experience with charting/data visualization libraries (Recharts, D3, Chart.js, etc.).
  • Experience with modern frontend tooling (Vite, Webpack) and CI/CD pipelines.
  • High ownership, strong judgment, and the ability to execute independently.

⭐️ Bonus points if you have

  • Experience with experimentation platforms, A/B testing, feature flags, or mobile app monetization.
  • Experience building or contributing to design systems.
  • Experience building production-grade, custom charting libraries

Why this role might be a great fitThis is a role for someone who wants their work to matter and have real impact.

At BlueThrone, you won’t spend weeks discussing button gradients in circles. You’ll ship, iterate, and improve fast.

You’ll fit here if…

  • You’re not waiting to be told what to do - you see the usability gap and solve it.
  • You care about building clean components, but you care even more about the user's ability to get the job done.
  • You’ve shipped real production systems (and dealt with the edge cases of complex data sets).
  • You prefer fast decisions, high trust, and a team that expects you to think like an owner.
  • You want to build the "brain" of a system that directly supports revenue growth.

If you want to build the frontend for a real monetization engine, not a demo - this is your seat 🎯
