Customer.io jobs, judged for you, free

What they do

Customer.io is a customer engagement platform. Companies use it to send automated email, push, in-app, and SMS messages, driven by real-time data on what people do in an app. Its products are Journeys, for messaging automation, Data Pipelines, a customer data platform, and Parcel, an email code editor. More than 11,000 brands use it. It started in 2012.

What they value

• Empathy, transparency, responsibility, and awkwardness: the four core values.
• Ownership: engineers own a problem from end to end.
• Product taste: engineers think like a user.
• Doubt about "the way things are done", with forward motion over best practice.
• Async work, written thought, and fewer meetings.
• A high bar and a low ego.
