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;
