Frontend Engineer

Rossum uses state-of-art AI plus intuitive UI to eliminate useless paperwork and make the whole world go faster. 

We are already processing up to hundreds of documents per minute. This volume grows exponentially, and the scope of our product only slightly slower.  This reflects also increasing requirements to our frontend where we face performance optimization challenges. Our mission is to deliver the same smooth top user experience no matter how the demand increases. 

Our Tech Stack

  • Our frontend is written mostly in TypeScript 
  • UI is build with React.js framework, fed by data from Redux state
  • We rely on functional programming principles and we like to enhance data immutability with a great help of  Immutable.js
  • RxJS supports our passion for reactive programming, moreover solving  asynchronous task management 
  • We are using and Playwright for end-to-end testing scenarios, together with Jest for our code’s unit testing. 
  • Our GitLab-based CI+CD pipelines are fine tuned to deliver continuously no matter how often needed
  • REST API serves the data

Pixel perfect UI is secured by CSS modules with Sass. While not having only one web application, we are sharing the components between multiple apps via npm package, developing them in Storybook, with designs provided by Zeplin.

One of our applications is written in the React Native framework as well.

About Rossum

We are automating document communication. Thousands of lifetimes per day are burned on manually dealing with documents in enterprise back offices. It’s a terrible job, and it makes the whole world go slower. Right now, we already process up to hundreds of documents per minute to save our users 85% of this work, serving some of the world’s best companies. Our mission is to create a world that builds rather than types, as companies that switched from email to Slack and Teams for internal communication next switch to Rossum for their orders and invoices.

We raised money from some of the best VCs in Europe and top American angel investors who backed startups like Airbnb, Revolut, or UiPath before. We are now pre-Series-A in terms of funding and grow 300% a year. (Learn more)
