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:
— Audit the current system, find weak points, and improve performance quality
— Build and execute performance and load testing strategy
— Ensure the product withstands large data volumes and heavy user load
— Cover core functionality with tests (automation + manual when needed)
— Propose engineering improvements, not just report issues
This is a role for someone who thinks as an engineer, not just a tester.
This role is based in our Lisbon office in a hybrid format. If you are not currently in Portugal, we are open to remote work during the trial period, with relocation to Lisbon afterward.
