  • Ability to roll up your sleeves and get things done.

  • A great communicator and team player.

Benefits



  • Generous equity package

  • Unlimited PTO (take time when you need it)

  • Top-of-market salary

  • Great healthcare

  • 401k

The process


We’re a startup and we’re making decision quickly. Our process is designed to give you the best glimpse of our team and allow us to evaluate your technical and culture fit.

  • Step 2: Virtual On Site: Technical and Leadership interviews
