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.

Zello keeps frontline workers connected with fast, reliable push-to-talk communication. Thousands of teams sign up to try Zello every month, and this role is the human at the front door: you make sure inbound prospects and trial signups get a fast, helpful response and a clear path to becoming paying customers. You'll also help build and sharpen the AI workflows that handle this transactional business at scale, so the system gets better every week.

After a Successful First Year, You Will Have

• Become the reliable first response for Zello's inbound inquiries and trial signups, consistently hitting response-time and conversion targets.
• Measurably improved the AI workflows that handle inbound, raising auto-resolution and lead-to-paid conversion versus today's baseline.
• Personally converted high-intent prospects the automation couldn't close, using a repeatable follow-up motion others can reuse.
• Built deep product and customer fluency, positioning you for your next step in the Revenue org (AE, CS, implementation, or solutions engineering).

What You'll Do

• Monitor, route, and respond to inbound inquiries and trial signups across channels.
• Tune and improve the agentic AI workflows that handle inbound; surface gaps, edge cases, and failure points.
• Step in directly on high-intent prospects, by email and phone, to convert them to paid.
• Track conversion and response metrics, and flag what's working and where the funnel leaks.
• Partner with Account Executives, Customer Success, and the team that owns the AI systems to close the loop.
• Build product expertise by working hands-on with Zello and talking to customers every day.

Who You Are

• You chase outcomes you can point to goals you set and hit, whether in work, school, sports, or a side project.
• You respond fast and write clearly; people understand you the first time.
• You learn software quickly and enjoy tinkering with AI and automation tools.
• You spot problems and fix or flag them without waiting to be told.
• You take feedback well and act on it you want to get better, fast.
• You stay organized and calm under a high volume of inbound.
• 03 years of experience; recent graduates are encouraged to apply.
• Professional working proficiency in English and Spanish (spoken and written) required.

This Role Is Not

• An outbound cold-calling seat the focus is inbound and trials.
• A platform-engineering role you tune and improve AI workflows, you don't build the underlying system.
• A dead-end seat it's designed to grow you into AE, CS, implementation, or solutions engineering.

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!
