EPUKI are recruiting for a Senior Infrastructure Engineer based at our EPUKI Leeds office.
The Senior Infrastructure Engineer is responsible for architecting, implementing, and maintaining robust IT infrastructure solutions across hybrid cloud and on-premises environments. This role bridges traditional infrastructure management with modern cloud technologies, ensuring seamless integration between legacy systems and cloud-native solutions. The position requires managing complex environments while maintaining high availability, security, and performance standards across all infrastructure components.
The role encompasses both strategic infrastructure planning and hands-on technical delivery, requiring collaboration with diverse stakeholders to align infrastructure capabilities with business objectives. The successful candidate will play a pivotal role in the organisation’s IT modernisation initiative, facilitating the transition from a traditional environment to a hybrid model. This includes managing cost, ensuring regulatory compliance, and optimising processes.
This is a hybrid-working role, with the expectation to be present at the office for a minimum of two days per week.
