• Hands-on experience supporting Cisco/network infrastructure

• Familiarity with project management tools and ITSM platforms (e.g., ServiceNow, JIRA).
• Strong troubleshooting, analytical, and autonomous problem-solving skills.
• Ability to work effectively in a small team environment, think on your feet, and openly share knowledge to strengthen overall team capability.
• Ability to build strong interpersonal relationships with team members and end users alike.
• Excellent written and verbal communication skills, including the ability to document systems and procedures clearly.
• Strong time management skills, with the ability to prioritize tasks in a fast-paced, results-driven environment.
• High attention to detail and a commitment to continuous learning and professional development.
• Flexibility and willingness to adapt to evolving technologies and requirements.
