DevOps Infrastructure IT Engineer Defence Sector
Location: Bristol – Hybrid 3 days a week on site
Employment: Permanent
Clearance: SC required (or eligible) — British Citizens only
Start: ASAP (subject to vetting)
About the Role
We’re seeking a hands-on, pragmatic DevOps Infrastructure IT Engineer to design, build, deliver, and support secure on-premises infrastructure across both internal systems and client environments.
This role is ideal for someone who thrives in highly secure, defence-aligned, fully on‑site engineering environments, working across the full stack—from Windows and Linux to firewalls, networking, virtualisation, and cyber security.
You will act as both a practitioner and a technical lead, collaborating with project delivery teams to ensure infrastructure is robust, compliant, and delivered with precision.
Important: This role is not cloud-focused. Candidates must demonstrate strong on‑prem engineering capability, Linux and Windows proficiency, and practical, step‑by‑step operational thinking.
Key Responsibilities
Infrastructure Delivery & Operations
Deliver full lifecycle on‑prem infrastructure solutions: design – deploy – configure – document – support.
Hands‑on ownership of:
- Windows Server, AD, Group Policy, DNS/DHCP
- Linux (Ubuntu / RHEL variants) – patching, updates, troubleshooting, CLI‑based operations
- VMware or Hyper‑V virtualisation
- Perform system hardening, health checks, and security uplift aligned with defence standards.
- Maintain and improve documentation, build standards, runbooks, and technical processes.
Technical Requirements
- Strong experience with both Linux and Windows Server environments.
- Expert knowledge of Active Directory, Group Policy, DNS, DHCP.
- VMware or Hyper‑V virtualisation.
- Firewall configuration and secure boundary design.
- Patch management, vulnerability remediation, secure system build.
- Experience working in air‑gapped or secure on‑prem environments.
- Understanding of Cyber Essentials, Defence, or MoD security frameworks.
Desirable (not mandatory)
- Microsoft certifications (MCSA, MS-102, AZ-104)
- VCP (VMware Certified Professional)
- CompTIA Security+ or equivalent
- PRINCE2 or ITIL Foundation
Soft Skills & Fit
We’re looking for someone who:
- Is a confident, capable on‑site engineer with strong customer presence.
- Loves hands‑on problem solving in real infrastructure — not just high‑level architecture.
- Communicates clearly with clients and colleagues.
- Is adaptable across industries (defence, engineering, manufacturing).
- Performs well under pressure and delivers against deadlines.
- Is happy to “turn their hand to anything” across infrastructure delivery.
Security & Eligibility
To meet MoD and client site requirements:
- British Citizenship is mandatory.
- Must have 5 years’ continuous, checkable UK residency.
- SC clearance required (or willingness/eligibility to undergo it).
Why This Role Will Suit You
This position is perfect if you enjoy:
- Working end‑to‑end on infrastructure—not just monitoring, not just cloud.
- Being hands‑on with Linux and Windows admin every day.
- Building and supporting secure systems used by defence‑aligned customers.
- Being part of a collaborative, on‑site engineering culture.
How to Apply
If you’re a practical, detail‑oriented engineer who thrives in hands‑on, secure on‑prem environments — we’d love to hear from you.
