Spin.AI is a global SaaS cybersecurity company that protects mission-critical data across Google Workspace, Microsoft 365, Salesforce, Slack & more. Our product – SpinOne – is a leading platform that unifies SSPM, ransomware protection, DLP, backup & recovery.
We’ve been recognized by Forbes as one of the Top 500 Best Employers and continue to scale rapidly. As we grow, our platform must confidently handle massive data flows and high-load enterprise environments and this is exactly where we need you.
🚀 We are looking for a Performance-focused QA Engineer who will help us strengthen system stability, identify bottlenecks, and ensure our platform can handle high-volume enterprise workloads. At the start of your journey with us, you will:

— Build and execute performance and load testing strategy
— Ensure the product withstands large data volumes and heavy user load

— Propose engineering improvements, not just report issues
This is a role for someone who thinks as an engineer, not just a tester.
