Job description

from Plain careers

Plain is redefining customer support for the next generation of B2B companies. We’re building the fastest, most powerful platform to help companies move beyond reactive support and build true customer relationships.

Some of the world’s most forward-thinking companies - like Cursor, Raycast, and Granola - trust Plain to unify all customer interactions, enable faster team collaboration, and supercharge their workflows with AI.

B2B customer support is undergoing a seismic shift. AI is transforming the way companies engage with customers, shifting support from a siloed function to a company-wide effort across Slack, Discord, and any other channel you talk to customers in. The old way - slow, manual, and disconnected - no longer works.

We’re looking for a Senior Product Designer to join our team and help us define the next phase of support tooling.

What you'll do

Design at Plain is about a lot more than pushing pixels in Figma, it’s about defining what support tooling should be. You’ll own problems end to end – from talking to customers, and coming up with new ideas all the way to tweaking animation easing curves in the front end.

You will:

  • Work on everything from early feature ideation, designing, and shipping a feature through to building and launching a landing page to announce it to the world.
