Help Build Europe's Hypersonic Capability

This organisation is redefining what's possible in European defence technology, delivering speed, resilience, and technological independence at a pace that sets a new standard. Operating as a small, elite, and highly capable team, it focuses on solving complex, high-impact problems quickly and effectively.

They are seeking anIT Systems Lead to take ownership of core IT infrastructure and operations within a talent-dense environment where every individual has a direct impact. This is not a predefined or siloed position, it is an opportunity for a high-calibre operator to shape, build, and run IT systems from the ground up, with the autonomy to define best practice and standards.

The successful candidate will play a critical role in ensuring secure, reliable, and scalable IT operations, directly contributing to the organisation's mission and Europe's broader technological independence.

The Role

The IT Systems Lead will:

  • Own the Microsoft environment end-to-end, including Entra ID, Windows endpoints, Intune/Autopilot (or GPO where appropriate), and core Microsoft server services
  • Build and operate IT infrastructure for a UK-based engineering workshop from the ground up, including secure network access, device provisioning, and endpoint compliance
  • Define and implement a hardened baseline across all endpoints, including MFA enforcement, least-privilege access, patching strategies, encryption, and standardised security policies
  • Act as the on-site IT authority, diagnosing and resolving issues quickly, documenting outcomes, and implementing preventative measures
  • Partner closely with international IT teams (including Linux/Kubernetes environments) to ensure consistent identity, access, and security controls across regions
  • Oversight and delivery of a new UK office move
  • Maintain high operational standards through clear documentation, asset management, streamlined workflows, and responsive user support

Candidate Profile

The ideal candidate will bring:

  • Proven experience owning and operating Microsoft environments in real-world settings (Entra ID, Windows endpoint management, Intune/GPO, and core server infrastructure)
  • A security-first mindset, with strong understanding of access control, system hardening, and auditability
  • The ability to operate autonomously with sound judgement, particularly in environments where they may be the sole on-site IT lead
  • A practical, solutions-focused approach, prioritising root cause resolution, prevention, and long-term system integrity
  • Experience working in fast-paced, high-performance environments where uptime, security, and delivery speed are critical
  • Curiosity and willingness to collaborate across technology stacks, particularly with Linux and Kubernetes-based systems

Security Clearance

Due to the nature of the work, applicants must be British citizens (or dual nationals with British citizenship) and eligible for UK Security Clearance (SC), with the potential requirement for Developed Vetting (DV).

What's on Offer

  • The opportunity to contribute directly to one of Europe's most consequential defence and technology challenges
  • High ownership and autonomy, with full responsibility for shaping IT systems and standards
  • Close collaboration with leading experts across engineering, operations, and defence
  • A fast-paced environment where ideas are implemented quickly and outcomes matter
  • A culture built on clarity, integrity, and excellence, supporting individuals who take initiative and operate with accountability
  • Competitive compensation and meaningful equity aligned to impact and responsibility

Where to Advertise Cyber Security Jobs in the UK (2026 Guide)

Where to advertise cyber security jobs UK in 2026: the specialist boards, communities and channels that reach offensive, defensive and GRC security talent. The candidate pool is small, heavily vetted and in high demand across government, financial services, critical national infrastructure and the private sector simultaneously. Many of the strongest candidates hold active security clearances, are not actively job-searching through general platforms, and move primarily through specialist networks and trusted referrals. General job boards reach a broad audience but lack the specificity that security professionals expect. Specialist platforms, government-affiliated channels and cleared candidate networks each serve a different part of the market. This guide, published by CybersecurityJobs.tech, covers where to advertise cyber security roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.

Cyber Security Jobs UK 2026: What to Expect Over the Next 3 Years

Cyber Security Jobs UK 2026: roles, salaries and the threat intelligence, cloud security and zero-trust hiring trends shaping UK cyber careers. Cyber security is one of the few sectors where demand for talent has never once dipped. Every major technological shift of the past decade — cloud migration, remote working, AI adoption, the proliferation of connected devices — has expanded the attack surface that security professionals are expected to defend. And every expansion of that attack surface has generated more jobs. But the cyber security jobs market of 2026 is not simply a larger version of what it was three years ago. It is a structurally different market. The threats have evolved, the technologies used to combat them have changed, the regulatory environment has tightened considerably, and the roles being created reflect all of that. A job seeker who understands only the cyber security landscape of 2023 is already working with an outdated map. The candidates who will thrive over the next three years are those who understand where the sector is heading — which specialisms are attracting the most investment, which technologies are reshaping defensive and offensive security practice, and how the definition of a cyber security professional is broadening well beyond the traditional image of a network defender in a SOC. This article breaks down what the UK cyber security jobs market is likely to look like through to 2028 — covering the titles emerging right now, the technologies driving employer demand, the skills that will matter most, and how to position your career ahead of the curve.
