Senior Front-end Engineer


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. 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. 
  • additional pages and features where we help users learn and extract the maximum value out of our core functionality and available integrations.

You can switch between these areas, or go deep on the one you love the most.

Our ideal buddy is:
  • Motivated to solve complex challenges. We are building a platform that provides General Purpose Computing to the masses; this requires cooking new solutions that handle millions of calculations. 
  • Professional and fun. We value professional commitment and the ability to stay optimistic and focused, especially in the face of difficult challenges or feedback. But we also find plenty of time to talk about The Big Lebowski.
  • 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!
