• Ability to troubleshoot Azure and hybrid network connectivity issues using hands‑on investigation, including effective routes, firewall policies, NSG rules, UDRs, DNS, VPN/ExpressRoute paths and end‑to‑end traffic flow analysis.
• Experience conducting network audits, health checks, configuration reviews and technical risk assessments.
• Excellent written and verbal communication skills, with the ability to explain technical issues clearly to customers, vendors and internal stakeholders.

• IT degree or equivalent combination of professional qualifications and practical experience.
• Experience across multiple network vendors, including Cisco, Palo Alto, Juniper, Fortigate, F5, Aruba or similar technologies.
• Experience with security controls such as IDS/IPS, network segmentation, remote access, vulnerability remediation and secure configuration standards.

• Decisive, calm under pressure and capable of delivering high‑quality outcomes despite operational constraints.
• Conscientious, organised and able to prioritise work effectively with limited direction.
• Strong troubleshooting, analytical thinking and communication skills, with the confidence to engage directly with customers and stakeholders.
• Technically curious and confident working beyond scripted procedures, with the ability to interpret symptoms, validate assumptions, test safely and resolve issues using first‑principles troubleshooting.
• Comfortable adapting their approach across varied customer environments, technologies and support models.
• Process‑oriented with excellent attention to detail and a strong focus on documentation, governance and service quality.
• Willing to mentor and support other engineers, helping to improve technical standards across the team.
