Middle QA Engineer (Manual)

Spin.AI is a global SaaS cybersecurity , Microsoft 365, Salesforce and Slack.

Our product – SpinOne unifies SSPM, ransomware protection, DLP, backup & recovery in one platform trusted by enterprise customers worldwide.

As our platform evolves and new features are delivered faster, the volume of manual testing has increased.

To keep our quality standards high and ensure stable releases, we are looking for a Middle Manual QA Engineer who takes real ownership of product quality.

We expect someone who thinks critically, challenges requirements, spots risks before they turn into incidents, and is comfortable diving into UI, APIs, databases, and backend workflows.

You will become part of a strong QA team of 7 engineers, including both Manual and Automation QA specialists, working closely together to maintain high product quality and continuously improve our testing processes.

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.

Validate data integrity and system behavior using database queries.

Run and analyze automated test results to identify problem areas, support root-cause analysis, assist with prioritization, and align on next steps with the team.
