Mid / Mid-Senior Full-Stack Engineer

Salary: £80k-£90k + Equity

Company: Mintstars.com – VC-backed creator monetization and payments platform

Location: London, UK

Join a high-output team building the infrastructure for the next generation of the creator economy. You will own end-to-end features for both MintStars' creator platform and MintCash, their B2B payments arm. This role focuses on shipping clean, pragmatic code across a modern TypeScript stack to solve complex payment and content delivery challenges.

Why this role is remarkable:

  • Work on a platform with a disruptive 5% fee model, directly impacting creator livelihoods while spinning out a sophisticated B2B payments infrastructure arm.
  • Join a lean, high-output team backed by top investors including Polygon, Escape Velocity, and Harvard Innovation Labs, offering high visibility and ownership.
  • Influence the technical direction of a product solving genuinely hard problems at the intersection of global payouts, smart routing, and content monetization.

What you will do:

  • Architect and ship end-to-end features including subscription flows, payout systems, and creator tooling using React, Node.js, and tRPC.
  • Build and maintain critical payment integrations with providers like Corefy and CCBill to support multi-rail processing and global payouts.
  • Enhance platform reliability and performance through improved observability, internal admin dashboards, and pragmatic, system-level thinking.

The ideal candidate:

  • Possesses 3-6 years of full-stack experience, ideally within a fast-moving startup environment, and is comfortable owning features without hand-holding.
  • Is an AI-forward engineer who treats tools like Cursor or Copilot as a genuine force multiplier to accelerate development and quality.
  • Demonstrates strong product instincts and a pragmatic approach to coding, with a preference for clean, maintainable solutions over complex over-engineering.
