QA Engineer Manual Testing

Spin.

AI is a global SaaS cybersecurity company that protects mission-critical data across Google Workspace, Microsoft 365, Salesforce, Slack & more. Our product – Spin One – 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.
