Plain is founded in London. We started Plain inspired by our experience helping scale Deliveroo from 10 to 2,000 people — and and have since grown to have team members all over Europe.

Plain is founded in London. We started Plain inspired by our experience helping scale Deliveroo from 10 to 2,000 people — and and have since grown to have team members all over Europe.

From Europe, we've expanded into the US, with the recent opening of our San Francisco office.

From Europe, we've built a product companies like Cursor, Vercel, n8n, Granola, Ashby and many others from around the world now rely on to power their support operations.

We're proud to be founded in London, based all over Europe, and expanding in San Francisco.

Doubling down
on London

Doubling down on London

So today we are doubling down on London.

We're building out a dedicated team here focused on advancing our AI efforts, working from our offices in Shoreditch. These are in-office roles, 3 days a week.

London remains one of the best places in the world to build product and engineering teams, and we're excited to invest here.

AI is rewriting what support can be. We think the future is not just in AI answering tickets or generating insights, but in building the infrastructure that enables companies to build their own AI agents, automations, and workflows.

Joining our AI team, you will:

  • Solve high impact, user facing problems. Your work can save teams countless hours by handling repetitive questions, reading code to prevent escalations, or surfacing product insights hidden in conversations. You’ll see a direct line from your work to happier customers and better products.

  • Enjoy autonomy and creative freedom. We’re a small, senior team. You’ll own broad areas, identify opportunities and ship fast. If you come up with an idea in the morning, there’s every chance you can ship a first version the next day.

  • Shape AI at the core of the product vision. Support is one of the most impactful frontiers for applied AI. We’ve built some great foundations already, now it's about reimagining how AI powers support end to end.

  • Write and speak about your work in the AI community – hosting and participating in events in our offices in London and San Francisco

Who we're looking for

Who we're looking for

Have the CEOs of other companies ever made a video for you?

People who are successful at Plain are curious, commercially aware, quick-thinking and high-agency. You'll work hand-in-hand with some of the most demanding, fastest-growing companies in the world, and take features and entire product areas from sketch to shipped.

If you want to meet people you'll take with you through your career and potentially even start something with, this is the place.

We are now hiring for the following roles:

Why Plain?

Why Plain?

We get it. You could join any other AI company in London. Why Plain? We'll list the top 3 reasons:

  1. Work on a broad set of applications. From our own AI agent Ari through to our AI assistant Sidekick and countless workflow improvements, our product surface is both rich and deep.

  2. Global exposure. We want to be very public about our work. You'll write and speak about our work, and help us shape our product in close partnership with some of the most advanced support organizations in the world.

  3. Customer support is one of the most complex and data-heavy software domains out there. Customers use Plain all day, every day, delivering mission-critical and highly technical support. You'll get feedback minutes after shipping, and ship the next iteration hours after. For product-minded engineers wanting to operate at the high water mark of complexity and criticality, this is it.

Our commitment to you is simple: We'll conclude your process within 7 days start to finish, make our entire team available to you, and give you great feedback you'll find useful regardless of the outcome. What do you have to lose?
