Interaction Designer

Desmos - San Francisco, California - Full time

At Desmos, we build technology that helps students learn math and love learning math. That technology is nothing without intuitive and delightful design.

The Desmos graphing calculator embodies that belief, packaging powerful technology in a beautiful and intuitive interface. The graphing calculator is quickly becoming the standard way for students to explore math through computers. More than 40 million people used the Desmos graphing calculator last year.

We’re taking everything we learned from our calculator and applying it to the development of groundbreaking activities ( that help math teachers create classrooms that are social and creative. We are seeking an interaction designer to design and develop powerful, intuitive, and delightful mathematical activities in close collaboration with our teaching team.

Desmos is based in the heart of San Francisco, and we’re looking for people who can work from our office.

What you should show up ready to teach anyone on your first day:

  • Examples of intuitive, delightful interaction design, including a few that you’ve worked on.
  • How to measure the effectiveness of a design.
  • How to evaluate design options and choose the best one, especially when designing for different audiences.
  • One thing you love about math.

What you’ll learn more about after you’re hired:

  • Our commitment to accessibility (, including the motivation for and requirements of various accessibility standards, and how to design from the ground up for users with disabilities (especially visual impairments).
  • Our company’s pedagogical commitments and the unique challenges of designing technology for classrooms.
  • The technologies that allow us to build performant, powerful, reliable browser-based experiences.

Within your first week, you’ll:

  • Introduce yourself on Slack to your new co-workers!
  • Collaborate with a member of the teaching team - make constructive suggestions for changes to an existing activity with an eye toward student experience and delight.

Within your first month, you’ll:

  • Brainstorm interactions in activities, evaluate options together with a member of the teaching team, and prototype the most promising interactions using modern design tools (AdobeCC, Sketch, InVision, etc).
  • Effectively communicate interaction ideas and design rationale to other members of our team.

Within your first three months, you’ll:

  • Write a style guide for activity interactions that improves communication and energizes activity development across our entire company.
  • Work with a cross-disciplinary team to bring an activity from brainstorming through design and classroom testing, with an eye on both efficacy of the lesson and detailed interactions.
  • Visit a local math classroom to see an activity in action.

Within your first year, you’ll:

  • Ensure that our activities maintain a high bar of always being delightful and intuitive.
  • Attend a math education conference with the Desmos team to get to know our users and better understand the role that Desmos plays in their classrooms.
