What’s Upflow?

  • We’re building a next generation, state-of-the-art payments platform for European businesses. We’re also a regulated financial institution (PSP license).
  • A growing, close knit team of 9 people (3 engineers) taking on a massive product and engineering challenge.
  • We’re addressing a huge customer pain in an extremely large market.
  • We think big - we’re building the next European fintech and want you to join us.
  • We’re in the latest eFounders batch, collectively our peers have raised over $120M in 2018. We’ve raised as well.

Job description

Our Stack

  • React on the frontend
  • Node, express, graphql, sequelize, postgres and redis on the backend.
  • We have two microservices: the payments stack & the api.
  • CI/CD through circleci, hosted on heroku, code on github
  • We have some legacy code in JavaScript, but we’re writing all the new stuff in Typescript

What you will do?

  • Own your work: lead projects from concept to completion. You’re in control of your own success.
  • Build & improve code across the entire stack (see below) for new and existing products.
  • Practice and encourage software engineering best practices: reasonable test coverage, appropriate modularisation, designing cohesive interfaces, and making the call on technical trade-offs.
  • Ship code to customers every week and measure its impact.
  • Collaborate in technical reviews to strengthen our architecture and system designs.

Preferred experience


  • Have an entrepreneurial mindset and are at ease in a very fast paced and rapidly changing environment.
  • 3+ years of industry experience in software engineering with full-stack web applications.
  • An expert in modern javascript development methodology, process and tooling (or are willing to become one).
  • Proven track record of designing and building extremely high quality user facing applications.
  • Pragmatic approach to engineering that strikes a balance between seamless experiences, beautiful code, maintainability, and time to market.
  • Appreciation for a test-driven, code-review culture.
