The job

Design System Engineers at Justworks build and maintain MILO, our internal design system, written in React and SASS. You will collaborate closely with designers and engineers on our product teams to create the building blocks that we use across our entire application. You will also help develop the processes and systems used in the day-to-day development and deployment of the design system.

What you'll do 

  • Build and maintain MILO, Justworks’ internal design system
  • Collaborate closely with designers to create beautiful, accessible patterns and components
  • Create and improve processes for developing and distributing a new design system
  • Help define best practices for front-end development throughout the organization
  • Have the opportunity to help build a new team, and make a large impact across the Justworks application

Who you are

You should have experience with React or a similar Javascript framework, and good knowledge of SASS, CSS, or something similar. You should also be knowledgeable about best practices for writing semantic, accessible HTML, and working with backend MVC web frameworks like Rails, Django, etc.

In addition, you should have:

  • UI sensibilities that emphasize HTML and CSS
  • A firm understanding of how the DOM and virtual DOMs work
  • Familiarity with front-end build processes, with particular knowledge about how SASS compiles to CSS, and Babel transpiles modern Javascript
  • Strong communication skills, especially when talking to non-technical stakeholders
  • A strong sense of product, and an appetite for understanding complex buisness logic
  • Familiarity and comfort with writing technical documentation
  • Interest in new technologies, with the ability to discern which ones are worth investing in

Any of the following are bonuses, but not requirements:

  • A background in design
  • Experience in scaling a design system from scratch
  • Experience managing or providing technical leadership for a team of engineers
  • Experience with front-end testing
