Software Development
58 200 € to 72 100 € / year

Imagine a spreadsheet grid where each cell can also call an API or repeat a job. This is what we are building. Our product lets users create interactive web apps using the spreadsheet skills they already have.

We have also been on the news. You can find us on TechCrunch, VentureBeat, Eco Sapo (PT), Business Insider (DE) and many other media about Rows.


Your responsibilities

Your role is to team up with our engineers and build our single-page app. You will be working on:

  • An account dashboard where users manage apps and settings.
  • The editor where users manipulate a list of programmable cells that can do computing, including services and automation.
  • Performance and reliability of our web app.
  • Additional pages and features where we help users learn and extract the maximum value out of our core functionality and available integrations.

About you

  • Focused on quality and usability. We hate alarms going off and features that are half-baked as much as you do. Come build a polished product with us!

What's in it for you?
