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. The Role As a Senior Software Development Engineer in Test (SDET) at Ditto, you’ll play a key role in ensuring our SDKs, tools, and platform perform flawlessly across mobile, web, and server environments. You’ll build, maintain, and scale automated test suites that validate Ditto’s distributed synchronization engine—powering real-time data consistency across millions of devices. Your work will help ensure that developers building on Ditto can depend on our SDKs to deliver bulletproof performance in any network condition.

Monitor and analyze test results to identify regressions, performance bottlenecks, and edge-case failures. Leverage modern test infrastructure Use BrowserStack, containerized test environments, and internal tooling to orchestrate complex test setups across devices and browsers. Automate reporting and triage workflows to provide actionable feedback to developers. Collaborate cross-functionally Partner with SDK and backend teams to define test coverage, reliability metrics, and release quality standards. Work with product and support to reproduce customer issues, verify fixes, and improve observability. Champion automation and best practices Contribute to testing standards, code review guidelines, and CI/CD enhancements. Mentor engineers on test strategy, maintainability, and continuous quality improvements.
