Customer.io is a versatile marketing automation tool for sending relevant messages based on behavior across web and mobile products.

Our robust platform enables you to:
- Automate your product messaging, with the ability to build, test, and send messages from one platform. 
- Create and manage newsletters, transactional messages, and behavioral messages 
- Do more with your behavior and data -- connect our powerful segmentation and automation engine with other apps to drive user behavior and save time.

Customer.io

Email, push notifications, text messages, in-app messages, webhooks: automated and powered by your data.

Hi, I'm Paul, VP of Engineering at Customer.io. We're always looking for thoughtful, driven Engineering Managers to add to our org. Some of our teams are building customer-facing product and workflows; others keep our distributed systems reliable, observable, and ready to scale. Whichever kind of problem energizes you, if you lead people well, hold a high technical bar, and drive work to completion without waiting to be handed a plan, we want to hear from you.

About Customer.io

Over 9,000 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—what people do or don't do inside a web or mobile app. Under the hood: Go, React, and AI help us ship fast and scale with confidence.

What We Value

Ownership. You set direction and see initiatives through. You create clarity when things are murky and set the path forward rather than waiting for one to be defined, and you're motivated by impact—not just intention. You hold yourself and your team accountable to shipping, not just staying busy.

Leaders who can do both. You operate at the strategic level and stay close to the technical work. You can align stakeholders on a plan and earn your engineers' respect in the same day—you don't choose between vision and execution, you hold both.

A drive to execute through resistance. Competing priorities, skeptical stakeholders, tired teams—you've moved work forward anyway. You name the resistance, make the call, and own the milestones and the misses.

An AI-first mindset. AI is central to how you build and how you lead your team to build. You have a real, concrete point of view on AI-native development, you use agentic tooling yourself, and you bring it into how your squad operates.

A healthy skepticism for "the way things are done." You bring rigor and pragmatism. Best practices matter—but never more than forward motion. You know when to build, when to buy, and when to wait—and you're comfortable making the call with incomplete information, then adjusting as you learn.

What You'll Do

Care deeply about our customers and their outcomesLead your squad to deliver real customer value by owning projects end to end—from planning through delivery, quality, and follow-throughDrive execution: set milestones, keep work moving through ambiguity and competing priorities, and ship in small, observable increments rather than waiting for a release windowMake confident decisions when the path isn't obvious, and lead your team through themSet the operating rhythm that helps your team move fastest, rather than defaulting to ceremony for its own sakeEnsure your squad's solutions are scalable, architecturally sound, flexible, and secure, with strong peer-review, QA, documentation, deployment, logging, and monitoring practicesStay close to the work—jump into design reviews, architecture calls, and incidents rather than watching from a distanceProvide direct, timely, and specific coaching, and create meaningful development opportunities for your direct reportsHire, onboard, and manage performance so the right people are in place to hit your squad's goalsBring an AI-native perspective—use AI tools to accelerate the team's velocity and help everyone prototype faster and ship smarterPartner across engineering and other departments to align efforts with customer success, and reach higher when our customers are having a bad day
