What’s the opportunity?

We are looking for a Senior Engineer to join the team that enables the core technologies that Intercom is built on.

This means that we’re here to help product engineers and ML scientists build simpler, more performant product - faster.

Previous projects from the team include future-proofing our databases through sharding and building a mechanism to migrate Elasticsearch indexes for scale and profit.

We’re building a robust platform where your expertise will be applied to areas such as building a beautiful Messenger, an efficient teammate experience, a secure by default system, all while scaling the platform to billions of users and shipping two hundred new versions of Intercom to production every day.
