IT Support Engineer

Most IT roles mean keeping the lights on while someone else decides how things should run. This one's different: you'll be the person on the ground building and running the infrastructure, with a CISO who trusts you to get on with it.

Minerva Defence is a UK sovereign defence technology company building the full stack of unmanned systems for modern warfare: hardware, software, networking, autonomy, navigation and effectors. Our mission is simple: to help ensure the UK and its allies can defend themselves in an era where major conflict is no longer unthinkable.

We are deliberately low-profile: no hype, no performative marketing, just execution. We ideate, design, and manufacture from start to finish right here in the UK. Our products are in active use on the battlefield today, delivering real operational impact in the most demanding environments. Despite operating largely in stealth, our team of 60 people is delivering disproportionate effect, with tens of millions in annual revenue across UK and non-UK customers.

Our culture is elite, innovative and mission-focused. We are built to be asymmetric: small in headcount, relentless in execution, and outsized in battlefield impact. We are looking for people who are not just talented, but committed: to the work, to the team, and to the purpose behind it.

You'll own the day-to-day running of our IT environment: onboarding new starters, supporting a fast-growing team, and managing a multisite WiFi setup across a mixed device fleet through Intune. You'll work closely with the CISO (who's remote, so you'll have real autonomy on site) to keep our security posture sharp and aligned with the standards that matter in this space. This isn't a ticket queue; it's a chance to shape how IT works here as the company scales.

Responsibilities

• Manage daily IT operations, including user onboarding, offboarding, and first line support
• Administer and maintain multisite WiFi infrastructure
• Manage a mixed device fleet using Intune MDM
• Maintain and develop our cloud-focused, zero trust network architecture
• Work with the CISO to maintain compliance with relevant security standards
• Monitor and respond to day-to-day security issues, escalating where needed
• Maintain documentation for IT systems, processes, and configurations
• Identify and implement improvements to infrastructure and tooling as the company grows

Requirements

Minimum:

• Hands-on experience with Intune and M365 administration
• Experience managing IT infrastructure with a security-first approach
• Eligible for UK SC clearance (UK citizen or 5+ years UK residency)
• Self-motivated, comfortable working with significant autonomy

Preferred:

• Experience in highly secure environments such as Defence, Government, or banking
• Familiarity with zero trust network architectures
• Experience supporting multisite WiFi deployments
