Infrastructure. Security. Ownership.

We're working with an organisation investing heavily in its technology estate and looking for an experienced Operations & Security Engineer to play a key role in modernising infrastructure, strengthening security and delivering technical change across a Microsoft environment.

This isn't a BAU support position. It's a hands-on project-focused role where you'll take ownership of technical work streams, deliver infrastructure improvements and help shape a secure, resilient platform that supports the wider business.

Working as part of a small, collaborative internal technology team, you'll have the autonomy to make technical decisions, influence best practice and see your work make a genuine impact.

You’ll split your time across infrastructure (around 60%) and security (40%), delivering projects that improve resilience, performance and cyber security.

• Leading infrastructure implementation and improvement projects.
• Managing and enhancing Microsoft Azure and on-premise infrastructure.
• Administering Active Directory, Group Policy and virtualised environments.
• Driving server lifecycle management and platform optimisation.
• Delivering security improvements including Active Directory reviews and Group Policy hardening.
• Supporting Cyber Essentials compliance and embedding security best practice.
• Identifying opportunities to optimise Azure consumption and reduce cloud costs.
• Producing high-quality technical documentation and following ITIL-aligned processes.
• Supporting occasional out-of-hours releases and joining a future on-call rota.

• Microsoft infrastructure technologies.
• Microsoft Azure.
• Active Directory and Group Policy.
• VMware/vSphere.
• Server lifecycle management.
• Infrastructure implementation and project delivery.
• ITIL environments.
• Cyber Essentials and infrastructure security improvements.

• Microsoft Intune.
• Power Shell scripting and automation.
• Azure cost optimisation, Reserved Instances and resource governance.
• NIST or ISO security frameworks.
• Microsoft technical certifications.

Technical capability is only part of the picture.

• Takes pride in delivering quality solutions.
• Is naturally curious and enjoys learning new technologies.
• Thinks commercially as well as technically.
• Can own problems from start to finish.
• Communicates confidently with both technical and non-technical stakeholders.
• Enjoys working collaboratively while being trusted to deliver independently.

This is an opportunity to join a business where technology is genuinely valued and where you'll have the freedom to make a real difference.

You'll work on meaningful infrastructure and security projects, have exposure to modern Microsoft technologies and be encouraged to continually develop your technical skills through ongoing learning and professional certifications.

If you're looking for a role where you can take ownership, deliver tangible improvements and help shape the future of a growing technology environment, we'd love to hear from you.
