Head of Technical Operations

We are seeking an experienced Technical Infrastructure Lead to take hands‑on responsibility for the infrastructure and platform services supporting our global operations.

• Maintain clear version control, testing and documentation for infrastructure automation.
• Continually identify opportunities to improve reliability and operational efficiency.

• Translate business and project requirements into secure, supportable technical solutions.
• Produce solution designs, implementation plans, configuration standards and technical documentation.
• Lead the technical implementation of infrastructure upgrades, migrations and new services.
• Review proposed solutions to ensure they meet architectural, operational and security requirements.
• Ensure new services are fully documented, monitored, backed up and supportable before entering production.
• Contribute practical technical expertise to wider transformation and change programmes.

• Provide technical oversight of LAN, WAN, wireless, internet and remote‑access services.
• Work directly with managed network providers to diagnose incidents and implement changes.
• Review network configurations, designs and performance information to ensure services meet business and security requirements.
• Validate work completed by service providers and challenge proposed solutions where necessary.
• Maintain sufficient internal technical knowledge to ensure effective control of outsourced network services.

• Apply security‑by‑design principles to infrastructure configurations and technical solutions.
• Work closely with the Head of Cybersecurity, Information Security to implement vulnerability remediation, secure configuration and access controls.
