Senior Systems Infrastructure Engineer

We are looking for a versatile Senior Systems Infrastructure Engineer who thrives on variety. You won’t be siloed into a single technology; instead, you’ll oversee a complex, high-security ecosystem spanning Windows, Linux, and modern Software-Defined and Cloud Data Centres.

Below covers everything you need to know about what this opportunity entails, as well as what is expected from applicants.

You are the “Safe Pair of Hands” for our infrastructure—capable of designing a network, automating a server build, and troubleshooting a production outage with equal precision.

This role is twofold, working on internal cutting-edge R&D projects alongside customer-facing delivery responsibilities for our clients.

Key Responsibilities

Full-Stack Infrastructure: Support the design, lead deployments, support the lifecycle management of high-availability servers, storage, and networking

Hybrid Environment Management: Administer a diverse production estate, ensuring seamless interoperability between Windows and Linux platforms.

Infrastructure as Code: Drive the shift toward automated deployments using tools such as Terraform and Ansible to reduce manual configuration.

Advanced Troubleshooting: Act as the final point of escalation for complex system defects, utilising deep-dive forensics across both physical hardware and digital layers.

Virtualisation Oversight: Maintain and optimise our virtualised environments (vSphere/vSAN) as part of a wider software-defined strategy.

What you'll Bring

Broad Systems Expertise: Deep Wintel knowledge (Active Directory, PowerShell, DNS/DHCP) combined with a solid foundation in Linux.

Automation-First Mindset: Experience (or a strong desire) to work with Configuration Management and IaC tools.

Hardware & Networking: A “builder” mentality—capable of configuring hardware and understanding the underlying network fabric (switching, routing, security).

Senior Leadership: The ability to take a project from a blank whiteboard to a fully documented production reality.

This role will ideally need high level of security clearance.

Job type: Full-time, permanent role within a stable, high-growth sector.

Balance: A genuine hybrid working model based in Basingstoke and the Southeast. Potential for international travel. xwzovoh

Perks: 25 days leave, private medical cover and a competitive pension.
