• Provide clear reporting on quality signals (coverage, trends, stability, release readiness) and recommend improvements based on data.
• Mentor and enable others to contribute to quality and automation through pairing, documentation, examples, and code review of test changes.

• Bachelor’s degree in computer science, engineering, or equivalent practical experience.
• 6+ years of experience in software quality assurance, with significant ownership of automation in production environments.
• Proven experience designing and maintaining automation frameworks and test infrastructure (not only writing individual tests).
• Proficiency in at least one programming language used for test automation (strong preference for C# or JavaScript/Type Script).
• Strong understanding of QA methodologies, defect triage, and building reliable quality signals throughout the SDLC.
• Experience testing systems with large datasets and complex workflows.
