Job Title: Mid / Mid-Senior Full‑Stack Engineer

Salary: £80k-£90k + Equity

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

Location: London, UK

Job Description

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.
