Director, Engineering

Hi, I’m Paul, VP of Engineering at Customer.io . I’m looking for an experienced engineering leader to own Customer.io 's product development engineering teams. The most important near-term project is delivering our new billing platform from the ground up. This is a high-priority, zero-to-one initiative with direct executive visibility — the kind of role where you'll set the vision, build the team, and drive the execution yourself. If you're energized by taking complex, ambiguous problems from near-zero to production and building the org to sustain them, this role is for 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. 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've led complex, zero-to-one engineering efforts — not just maintained and scaled existing systems — and you know what it takes to drive them to completion across an organization.

Engineering leaders who can do both

You operate at the strategic level and stay close to the technical work. You can align executives on a roadmap and earn an engineering team's respect in the same day. You don't choose between vision and execution — you hold both.

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.

An AI-first engineering mindset

AI is central to how you build and how you lead your team to build. You've developed a real point of view on AI-native development, you can speak to it concretely, and you bring it into how your org operates.

What You'll Do

• Own the vision, roadmap, and execution for Customer.io 's billing platform: a custom, in-house system built for real SaaS complexity — usage-based billing, subscription management, and multi-tier pricing
• Partner with Product, Finance, and Engineering leadership to align billing strategy with company goals and unlock Customer.io 's next phase of growth
• Make build-vs-buy decisions with conviction, and lead the team through them
• Mentor and develop engineering managers and senior technical leaders on your team
• Drive a culture of accountability, transparency, and continuous improvement across the org
• Leverage AI tools to accelerate team velocity and bring an AI-native perspective to how the team builds

What We're Looking For

• 12+ years of software engineering experience, with 8+ years leadi
