We are seeking a Senior IT Engineer (Infrastructure and Security) to take a leading role in maintaining, securing and improving a complex technology environment. You will be responsible for the availability, performance and resilience of core infrastructure, while helping to strengthen security controls and support the organisation’s wider technology strategy. This is a hands-on role requiring strong technical expertise, sound judgement and the ability to work effectively with colleagues, suppliers and stakeholders at all levels.

Your responsibilities will include managing and supporting server, cloud, network, storage, backup and virtualisation platforms; monitoring systems and resolving incidents, problems and service requests; and contributing to infrastructure upgrades, migrations and continuous improvement initiatives. You will help develop and maintain robust security measures, including vulnerability management, patching, access controls, endpoint protection, logging and incident response.

Experience with security monitoring, risk assessment, automation, scripting and infrastructure-as-code would be advantageous. Relevant professional certifications are desirable, alongside a strong understanding of IT service management and change control. You will be an analytical and proactive problem-solver who can prioritise effectively, communicate clearly and explain technical issues to non-technical audiences. A collaborative approach, strong attention to detail and a commitment to protecting systems, data and services are essential.
