Intercom

Senior Full Stack Engineer - Team Web

London , United Kingdom

AI overview

Contribute to the future of our website by designing and developing end-to-end web solutions while collaborating cross-functionally to create seamless user experiences.

Intercom is the AI Customer Service company on a mission to help businesses provide incredible customer experiences. 

Our AI agent Fin, the most advanced customer service AI agent on the market, lets businesses deliver always-on, impeccable customer service and ultimately transform their customer experiences for the better. Fin can also be combined with our Helpdesk to become a complete solution called the Intercom Customer Service Suite, which provides AI enhanced support for the more complex or high touch queries that require a human agent. 

Founded in 2011 and trusted by nearly 30,000 global businesses, Intercom is setting the new standard for customer service. Driven by our core values, we push boundaries, build with speed and intensity, and consistently deliver incredible value to our customers.

What's the opportunity?

Our company website is the centerpiece of our brand — the public source of truth about Intercom’s products and the number one driver of leads for our demand generation team. Intercom.com and Fin.ai sit at the intersection of awareness, product marketing, demand, and support, requiring robust, performant, and reliable infrastructure as much as polished user-facing interfaces.

We’re looking for a Senior Full Stack Engineer to join Team Web, who is passionate about crafting intuitive front-end experiences and building the backend systems and tools that power them. You’ll play a key role in shaping the future of our website across the full stack, from UI to infrastructure, while collaborating with product marketers, designers, and engineers across the business.

Intercom

Intercom is a fundamentally new way for internet businesses to communicate with customers, personally, at scale. It's a customer communication platform with a suite of integrated products for every team—including sales, marketing, product, and support. Our products enable targeted communication with customers on your website, inside your web and mobile apps, and by email. This contrasts with the old way where a business uses a tangle of point solutions, like marketing automation or helpdesk products, with every team operating in a silo. This makes it hard for teams to work together and be on the same page, resulting in a disjointed and very impersonal experience for the customer.
