Note: The job is a remote job and is open to candidates in USA. Klaviyo is hiring a Software Engineer II for its Mobile App Growth team, which owns the Android SDK and related mobile products. The role focuses on building and maintaining Android SDK features while contributing to other mobile SDKs, backend services, and customer-facing integration resources.

Responsibilities

• Design, build, and ship features and fixes to the Android SDK — your primary area of ownership — used across a huge range of third-party apps and OS versions/devices
• Pitch in on our other mobile SDKs (iOS, React Native, Expo, and Flutter) when priorities call for it; you don't need to be an expert everywhere, but you should be willing to get hands-on
• Contribute to the backend services, infrastructure, and embedded web UI that power products like in-app messaging, universal linking, and geofencing — including newer greenfield work like mobile inbox
• Diagnose and resolve SDK issues reported by customers
• Write clean, well-tested code and participate in code and design review
• Collaborate with product and other engineering teams to keep tracking and messaging behavior consistent across platforms
• Contribute to documentation, sample apps, and integration guides that customers use to adopt the SDKs

Skills

• 1-3 years of professional Android development experience, ideally including Kotlin
• You don't need heavy oversight to make progress; you take a problem, figure out the right questions, and drive it to done
• You treat outcomes as yours end-to-end, not just the code you personally typed
• Willing to pick up iOS, backend, or frontend work when it falls under the team's ownership; you don't need to be an expert everywhere
• Experience shipping and maintaining production Android code, with a solid grasp of the Android lifecycle, threading, and Gradle
• Used to debugging across a wide matrix of devices, OS versions, and third-party app environments, since SDK work means you don't control the host app
• Familiar with testing practices (unit, integration, instrumentation) and CI/CD for mobile
• You'll work with customers' engineering teams as well as your own
• Comfortable with webviews and location services, and open to picking up new technologies (Python, React, AWS) as the team's surface area grows
• Experience building or maintaining an SDK/library (versus an app), exposure to iOS/Swift or backend services, familiarity with push notification/messaging systems, or contributions to open source

Benefits

• This role is open to fully remote work from within The United States
• Company’s annual cash bonus plan
• Variable compensation (OTE) for sales and customer success roles
• Equity
• Sign-on payments
• A comprehensive range of health, welfare, and wellbeing benefits based on eligibility
