I'm reaching out with an opportunity to join one of the UK's fastest-growing payments start-ups that's scaling at 5-10% growth every week since launch.

They've built tools that empower small businesses worldwide -- from card readers that cost less than half of Square or SumUp, to slick mobile and web apps driving real impact for independent merchants.

They're now looking for an experienced TypeScript Node.js Engineer to join their product & engineering team and help build the next generation of their platform.

What you'll be doing:

Designing and building features across their backend stack: APIs (Express), Postgres, Redis, and Node.js
Owning greenfield projects while helping maintain existing APIs
Collaborating with a squad of 4-5 developers to deliver end-to-end features
Championing code quality, scalability, and testing (unit + e2e)

What they're looking for:

Strong experience with Node.js + TypeScript
Proficiency with SQL (Postgres/MySQL) & Redis
Experience with payment providers (Stripe, Braintree, etc.)
Familiarity with POS applications
Test-driven development mindset

What's on offer:

Competitive salary + stock options
Apple MacBook Pro + company-issued phone
PS500 home office allowance
Hybrid working (2 days/week in London near Chancery Lane)
A chance to make your mark in a truly disruptive, fast-scaling fintech
