• Experience with testing methodologies, tools, and best practices.
• Excellent communication and collaboration skills, with the ability to influence technical decisions.
• Strong problem‑solving and analytical skills.
• Experience with continuous integration/continuous deployment (CI/CD) pipelines.
• Hands‑on experience with CI/CD pipelines and tools, particularly Jenkins.
• Proficiency working in a Linux environment.
