The Mission
We are looking for a versatile Senior Systems Infrastructure Engineer who thrives on variety. You will not 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. 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, and 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 Windows knowledge (Active Directory, PowerShell, DNS/DHCP) combined with a solid foundation in Linux.
* Automation‑First Mindset: Experience (or 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.
* Active DV Clearance: Required due to the sensitive nature of the environments you will support.
The Benefits
* Financial: Up to £80,000.
* Security: Full‑time, permanent role within a stable, high‑growth sector.
* Balance: Genuine hybrid working model based in Basingstoke and the Southeast, with potential for international travel.
* Perks: 25 days leave, private medical cover, and a competitive pension.
We welcome applications from all individuals, regardless of background or identity, and we encourage candidates who may not meet every listed requirement to still apply. If you require any adjustments or support during the recruitment process, please let us know and we will work with you to ensure a fair and accessible experience.
