• Conduct security reviews, configuration audits, compliance validation, and quality control assessments
• Create engineering work packages, implementation plans, migration procedures, and rollback documentation
• Collaborate with architects, operations, cybersecurity teams, and vendors to deliver network solutions
• Mentor junior engineers and contribute to standards, best practices, and continuous improvement initiatives
• Participate in after-hours maintenance and provide escalation support for critical network incidents as part of an on-call rotation
