• Experience troubleshooting and supporting applications in production environments.
• Strong understanding of software engineering best practices, including automated testing, code reviews, CI/CD, observability, and secure development.
• Strong communication, analytical, and problem-solving skills.
• Bachelor's degree in computer science, Information Technology, Information Systems, or a related field (or foreign equivalent degree) or equivalent work experience
