  • Work effectively with both on-site teams and remote team members (including supervision of remote personnel across different countries).
  • Maintain excellent in-person and remote communication skills, ensuring clear, concise, and timely updates.
  • Operate within ticketing systems like Freshdesk/Freshservice, Microsoft Teams and Slack to manage and resolve support requests and internal communication.
  • Candidates must be proficient in using Jira for issue tracking and project management, ensuring effective collaboration with both remote and on-site teams and maintaining clear task documentation throughout the deployment lifecycle.
