Who are Plain?
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 real customer relationships.
Some of the world’s most forward-thinking companies — including Cursor, Ashby, Vercel, and Granola — use Plain to unify customer interactions, collaborate faster, and supercharge their workflows with AI.
We’re a small, tight-knit team with offices in San Francisco and London, and teammates across Europe. This role is remote EU-based , with the option to work from our London office up to 3 days a week.
The role
This is not a “ticket taker” role.
As one of our early Support Engineers, you’ll be a clear owner of support during EU hours and a founding member of the function . You’ll combine technical depth, strong judgment, and proactive communication to ensure customers, and the rest of the company, always feel support is under control.
You’ll work directly with Product and Engineering, act as “customer zero” for the product we’re building, and help shape how support operates at Plain as we scale.
Many of our customers are technical, so you’ll regularly move between APIs, webhooks, SDKs, logs, and architecture discussions and then translate that complexity into clear, confident guidance for customers.
You’ll have real ownership and immediate influence in how support and the product itself evolves. If you’ve ever wanted to build the support experience you wish you’d had at previous companies, this is that opportunity.
What you’ll do
Own support during EU hours
Lead handover and cross-timezone coordination
Shape how support works at Plain
Be “customer zero” for the product
What success looks like
After a few months, people should feel that:
This is a great fit if you…
This won’t be the right role if you…
