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

Salary: £80k-£90k + Equity

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

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.

Location: London, UK

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.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
