Job description
from Plain careersPlain 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, Vercel, 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.
This role is hybrid with 3 days a week in our London office.
What you'll do
Engineering at Plain is about much more than moving tickets from left to right - it’s about owning and solving problems end to end, from infrastructure decisions to feature design to button copy.
You will:
Build across the stack: frontend interfaces, backend logic, and everything in between
Ship high impact features that are fast, reliable, and delightful
Contribute to product and technical direction, working closely with design, engineering, and founders
Collaborate tightly with customers to understand their problems and solve them elegantly
