This is a full remote job, available from South America, North America, and Central America.

Hello, I'm Paul, VP of Engineering at Customer.io. We're looking for curious and driven full-stack engineers who want to own big things and delight our customers. You'll design, build, and ship the core product experiences our customers rely on, while helping the team push boundaries on what great communication tools can do.

About Customer.io:

Over 8,000 companies, from scrappy startups to global brands, use our platform to send billions of emails, push notifications, in-app messages, and SMS every day. Customer.io powers automated communication that people actually want to receive.

We help teams send smarter, more relevant messages using real-time behavioral data. Under the hood, we use Go, React, Ember, and AI to ship fast and scale with confidence.

What We Value:

Ownership: You own problems end to end. You move fast, act like an owner, and thrive in ambiguity. You've led complex projects before, whether officially or not, and you're ready to do it again.

Engineers with product taste: You think like a user, not just an engineer. You care about frontend polish, backend performance, and everything in between.
