Senior Software Engineer, MeshLab

Overview

About Ditto. Ditto is redefining how data moves at the edge. Our mission is to make it seamless for developers to build resilient, real-time applications, regardless of network conditions. Whether you're in a stadium, airplane, or remote military base, Ditto's peer-to-peer sync engine ensures devices stay connected and data stays consistent, even without internet. With more than $145 million in funding and trusted by organizations like Chick-fil-A, Delta Airlines, and the U.S. military, Ditto powers mission-critical experiences across aviation, retail, travel, hospitality, defense, and more.

As a globally distributed, fast-growing startup, we’re committed to building a diverse and inclusive team that reflects the wide range of perspectives needed to solve the world’s hardest connectivity problems.

We are seeking a Software Engineer to build and lead Ditto's Mesh Lab automation initiative. The Mesh Lab is our internal device testing infrastructure where we validate Ditto's SDK performance across hundreds of physical devices representing real-world deployment scenarios. You'll transition our manual testing processes into a fully automated, scalable testing framework, ensuring the reliability of our technology across diverse hardware configurations, operating systems, and network conditions.

This is a unique opportunity to work at the intersection of hardware and software, building the testing infrastructure that validates our edge sync platform for customers in aviation, retail, government, and enterprise sectors.
