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 is the push-to-talk platform that connects millions of frontline workers, and the AI & Data team builds the agent systems that run the business behind it. We have more high-value AI work than we have capacity to build, and we need someone who can both ship it and hold a real engineering standard around it. You would be the person who makes our agent work genuinely engineered - tested, reviewed, monitored - and who raises how everyone here builds.
Shipped and operated production agent systems that people across Zello use every day
Made evals-driven development the team's default, so every agent ships with an eval suite and monitoring
Owned the code review bar for agent work and raised the standard it is held to
Measurably levelled up teammates' engineering craft through review, pairing and coaching
Cut the time it takes to move an agent from prototype to production
Build LLM-backed systems end to end and put them in front of people who are not engineers
Design eval suites and monitoring before shipping, not after something breaks
Review agent pull requests and explain why a design will or will not hold up
Operate what you ship: triage drift, chase down silent failures, fix root causes
Set engineering conventions the team actually adopts - testing, structure, error handling
Pair with and coach teammates who are strong analysts and newer to software craft
Tell us when AI is the wrong tool for a problem, before we build it
You learned to program properly, and you can reason about code you did not write
You build things nobody asked you to build
You treat tests and evals as part of shipping, not as cleanup afterwards
You give code review feedback people act on, and you coach rather than direct
You connect engineering standards to outcomes rather than to taste
You hold a high bar without making people feel small about it
You have operated production systems that other people depended on
Not a research role. No papers, no training models from scratch
Not a front-end or product design role. The interfaces here are internal and functional
Not a management track. This is an individual contributor seat with real influence over how the team builds
Not a prompt-engineering role. This is software engineering applied to AI systems
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!
