• Experience writing and supporting batch programs.
• Strong appreciation for logging and error handling in production systems.
• Hands-on experience with Docker and Kubernetes.
• Cloud services development experience.
• Experience using code-scanning tools and resolving security, quality, and standards findings.
• Comfortable working in Agile/Scrum teams using JIRA and Confluence/Wiki.

Nice to have
