We have a simple mission at Calm: To make the world a happier and healthier place.

The heart of Calm is digital but the brand is expanding offline into a variety of products and services that bring more peace, clarity and perspective into people’s busy lives. We are building Calm into the Nike of the Mind. We believe Calm can become one of the most valuable and meaningful brands in the world.

Over 50 Million people have downloaded the app and we are growing by 85,000 new downloads a day. The company is profitable and headquartered in San Francisco, CA.

Calm was co-founded by Alex Tew (Million Dollar Homepage) and Michael Acton Smith (Mind Candy, Moshi Monsters, Firebox).

Calm is a small team of engineers solving large scale challenges. The Backend team is the heart of the calm infrastructure. It powers everything from content display to subscriptions. We are constantly developing new features and experiences that help our users get the most out of Calm. This role is incredibly important; we currently operate a node.js monolith on a 300+ pod Kubernetes cluster to serve our high request volume. Help us take Calm’s infrastructure to the exciting next level, powered by microservices. Be a key player in the exciting process of re-envisioning the hidden technology that powers the Calm app. Come join a small, fast moving team that is tackling some of the most fun engineering problems out there.
