About the Role

We're looking for a design engineer who loves working on complex problems and designing products that power-users love to use on a daily basis.

  • Partner closely with our product and engineering teams. You’ll work to establish and implement a design system that enables rapid product iteration.

Ideal Candidate Credentials

  • You have experience designing zero to one B2B products with complex requirements.
  • You enjoy building things and are familiar with modern devtools (send us a link to your Github!).
  • You have owned problems end-to-end, and are willing to pick up whatever knowledge you’re missing to get the job done.
  • You have thrived in environments where things are sometimes loosely defined and may have competing priorities or deadlines.

Benefits Include

  • Medical, dental, and vision insurance
  • Daily lunch, snacks, and beverages
