• Proficient in working with Linux (shell, log analysis, and networking fundamentals)
• Basic understanding of containers and Kubernetes-enough to perform installations following instructions, check deployments, and systematically isolate errors
• Experience testing backend services and APIs (REST, common error patterns) and highly confident in handling asynchronous systems and their associated challenges (timing, race conditions)
• Basic understanding of Node.js-based backends
• Experience in frontend testing (functional, regression) and a basic understanding of Angular (specifically components and services)
• Known for structured, precise, and reliable test documentation
