• Designing, implementing, and maintaining complex automated test scripts and contributing to the development and upkeep of the team's automation platforms, with a strong focus on expanding coverage and improving efficiency;
• Reporting issues through the bug tracking system, conducting root cause analysis, and following defects through to resolution, including validating fixes and assessing the impact of code changes;
• Producing manual and automated test run reports and communicating results, status, and quality metrics to the release owner to support go/no-go decisions;
• Owning and monitoring quality metrics and indicators within your area of responsibility, and participating in risk analysis for product and module functionalities;
• Researching, recommending, and implementing tools and approaches that improve the testing process, product quality, and overall automation level;
• Using modern AI-based tools to improve testing efficiency, test design, analysis, and automation workflows, while applying sound judgment to validate results;
• Mentoring and helping train Junior QA Engineers — supporting them in clarifying specifications, reporting and reproducing defects, and growing their technical skills;
• Sharing technical knowledge across teams and delivering clear documentation and workshops in your area of expertise;
• Contributing to the technical evaluation of team members' performance and to the assessment of candidates' technical competencies for open positions, in line with company procedures;
• Identifying training needs and organizing sessions to raise the overall quality standard of testing;
• Reproducing and investigating errors reported by customers, collaborating with Technical Support and the Cyber Threat Intelligence Lab to identify root causes;
• Ensuring that the product meets all target requirements and quality standards before each release.

• Experience with macOS or Linux;
• Strong scripting skills, preferably in Python or Bash, and solid hands-on experience in QA automation;

• Openness to using AI tools in day-to-day work, with a practical mindset and the ability to critically assess the results;
• Strong critical thinking and analytical skills — testing starts with the first requirements and continues throughout development;
• Very good attention to detail and a meticulous approach to quality;
• Basic to intermediate networking knowledge, and a good understanding of the technology and architecture behind the products;
