The Role:

We’re looking for a Software Engineer to own and evolve Fadmin, our internal admin tool that powers the day-to-day operations of Fanvue. Built on React, Prisma, and Material UI, Fadmin is used by teams across the company to manage everything from creators and content to payments and user support. You’ll play a key role in shaping the backbone of how Fanvue operates, working closely with product managers, engineers, and ops teams to build intuitive, high-quality internal tools.

Your work will focus on crafting seamless, efficient interfaces while ensuring clean server integration, structured database management, and long-term maintainability of the platform.

What You’ll Do:

• Design and implement CRUD interfaces and custom views using React-Admin.
• Create and manage database queries and mutations using Prisma ORM.
• Style and layout components using Material UI (MUI) for consistent UI/UX.
• Analyze and migrate business logic and data queries from Retool to a custom React-Admin-based interface.
• Optimize application performance and user experience across different teams using Fadmin.
• Work with authentication/authorization mechanisms (e.g., role-based access).
• Write clean, maintainable code and contribute to internal documentation.
• Support ongoing improvements to developer experience and internal tooling.

Who You Are:

Must-haves:

• Proficiency in React and modern JavaScript/TypeScript.
• Experience with React-Admin and Material UI (MUI).
• Solid understanding of Prisma and relational databases like PostgreSQL.

• Comfort refactoring legacy code and migrating existing queries into structured code.
• Strong communication skills and a collaborative mindset.

Nice-to-haves:

• Experience with Retool or other low-code internal tooling platforms.
• Familiarity with Node.js and ideally Next.js (not essential can be picked up).
• Previous experience in a fast-moving startup environment.
