Job Description

You will own features end-to-end across a creator monetization platform and its new B2B payments infrastructure arm.

This role requires a pragmatic engineer who leverages AI tools to ship high-quality code at speed.

Why this role is remarkable

• Join a fast-growing team backed by top-tier investors including Polygon, Escape Velocity, and Harvard Innovation Labs during a high-leverage spin-out phase.
• Enjoy genuine ownership in a lean, high-output environment where your code directly impacts global creator payouts and multi-rail B2B payment processing.

What You Will Do

• Design and implement end-to-end features across the creator platform, including subscription modules, content delivery systems, and creator-facing dashboards.
• Build and scale robust B2B payments infrastructure (MintCash) handling multi-rail processing, global payouts, and smart routing integrations.
• Enhance platform reliability and observability while using AI force multipliers like Cursor or Copilot to accelerate the development lifecycle.

The ideal candidate

• Has 3–6 years of full-stack experience with React/Next.js, Node.js, TypeScript, and Prisma, ideally within a fast-moving startup environment.
• Demonstrates an AI-forward workflow, using modern LLM-based coding tools daily to increase productivity and maintain high code quality.
• Possesses a pragmatic, product-focused mindset with the ability to own complex features independently and a desire to solve hard fintech problems.
