- Agile and Quality-Focused: You excel in dynamic Agile teams, advocating for robust integration testing, consistent automation, and efficient defect tracking. ISTQB certification is considered a significant advantage, reflecting your commitment to the highest testing standards.
- Business Domain Awareness: Prior experience in payments, banking, or fintech is desirable, as it enables deeper understanding of business-critical requirements and regulatory challenges.
