ABOUT ZELLO Zello is a voice-first communication platform, powered by our industry-leading push-to-talk technology, to improve collaboration and productivity for desk-less workers. With over 175+ million users, we’re the #1 rated push-to-talk app in the world, delivering 9 billion (yes, with a B) messages a month.  At Zello, our company values are at the heart of what we do everyday. We’re proud to serve the frontline, we’re privileged to connect people in times of crisis across the globe, and we’re honored to support first responders. And this is where you come in. This role is on Zello's Android team, the team that builds and ships the apps carrying 80% of Zello's revenue. You'll join a four-person team where your work is visible from day one and what you ship is felt by every Zello customer running on Android. AFTER A SUCCESSFUL FIRST YEAR, YOU WILL - Have owned and shipped multiple features across a focused area of the Android codebase, with clean code, appropriate test coverage, and minimal regressions in production. - Have made a concrete contribution to Android 2.0 — migrated a module to the new Hilt-based pattern, completed a plugin migration, or built a new component in the target architecture. - Have driven a measurable quality outcome in your area: reduced crash rate, fixed a top customer-impact bug, or shipped a stability/performance win that landed in production. - Have become fluent in Zello's AI-assisted dev workflows (CLAUDE.md [Upgrade to PRO to see link] .cursor/ rules, bug-hunter skill, AGENTS.md [Upgrade to PRO to see link] and contributed at least one improvement back. WHAT YOU'LL DO - Own and ship features end-to-end across a focused area of the Android client. - Write production Kotlin daily, with Java when navigating legacy code. - Treat tests, code review, and stability as part of "done" — not afterthoughts. - Contribute to Android 2.0 rearchitecture: Hilt-based DI, modular Gradle, plugin patterns, MVVM/MVI. - Use Zello's AI-native dev workflows daily — and contribute improvements back to the team's agent library. - Pair, review, and align on shared standards with a four-person team. WHO YOU ARE - You've shipped production Android in Kotlin for at least 2 years. Java doesn't scare you when you navigate legacy code. - You've worked in modern Android architecture (DI, modular Gradle, MVVM or MVI) on real codebases — not just toy projects. - Your definition of "done" includes tests, low crash impact, and clean code review. - You use AI-assisted dev as a default, not a novelty. You have a point of view on what works and what doesn't. - You take ownership of focused scope and ship without hand-holding. - You take code review feedback well and come back better — no ego, no chase. THIS ROLE IS NOT - A senior or staff role with mentorship of others built in. You're shipping at a high mid-level bar with room to grow. - A pure architecture role. Android 2.0 contribution matters, but you're judged on shipping high-quality features first. - A backend or full-stack role with Android as a side gig. We need an Android-first engineer. - A role where you wait for direction on every ticket. Mid-level here means you take focused scope and run. We hire for potential, passion for our mission, and a knack for solving difficult problems over checking every qualification box. We have competitive pay, equity with significant upside, and intentionally design our benefits to encourage healthy and well-balanced employees, flexible schedules and time off. We even offer a sabbatical after every five years of service so you’re able to pursue and enjoy what matters most to you. And of course, we wouldn’t be a technology company without a ping-pong table and free snacks in our break room. Join us!
