About the Role

At Customer.io in the Computer Software space, Empower your customers with unified, real-time engagement at scale.

<p>Hi, I'm Paul, VP of Engineering at <a href="http://Customer.io">Customer.io</a>. We're looking for a staff engineer to set technical direction for the systems that move billions of messages a day. This isn't a role about shipping more, faster. It's about deciding what gets built, where the architecture needs to go next, and raising the ceiling for the engineers around you.</p>

<h2>About <a href="http://Customer.io">Customer.io</a></h2>

<p>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. <a href="http://Customer.io">Customer.io</a> powers automated communication that people actually want to receive.</p>

<p>We help teams send smarter, more relevant messages using real-time behavioral data. Under the hood: Go, React, Ember and AI help us ship fast and scale with confidence.</p>

<h2>What We Value</h2>

<p><strong>Ownership at company scale</strong></p>

<p>You take on the problems nobody has claimed yet — the ones that span squads, have no obvious owner, and would quietly cost us a year if left alone. You either solve them or get leadership aligned to.</p>

<p><strong>Engineers with product taste</strong></p>

<p>You think like a user, not just an engineer. You connect architectural decisions to what customers actually experience, and you can explain that connection to people who don't write Go.</p>

<p><strong>A healthy skepticism for "the way things are done"</strong></p>

<p>You retire practices that have outlived their usefulness, including ones you helped build. Best practices matter — but never more than forward motion.</p>

<p><strong>Force multiplication</strong></p>
