Requirements - Proven ability to operate as Level 3 support, including deep troubleshooting, structured root cause analysis, ownership until resolution. - Ability to communicate clearly with customers (technical and non-technical stakeholders), internal teams (L1/L2, architects, project teams, vendors). - Strong documentation discipline and operational mindset. - Ability to mentor L2 administrators and contribute to knowledge transfer. - Calm and structured behavior during major incidents. - Excellent English communication skills, both verbal and written. - Availability for on-call responsibilities, extended hours, and participation in planned maintenance windows - which may occur during evenings or weekends with shifts rotated among team members.
