This is a rare opportunity to take ownership of cyber security architecture at national scale, sitting at the heart of a programme with real national significance. Backed by substantial government investment, our client is developing a world-first resilient infrastructure capability designed to protect the critical services that modern society depends on, including telecommunications, banking, transport and emergency response. As Principal Security Architect, you will serve as Security Pillar Lead across a portfolio of complex programmes, shaping strategy, leading assurance, and ensuring that the technology underpinning essential national services is built to remain secure and robust under any conditions.

Key Responsibilities:

  • Lead the cyber security architecture and design function across a portfolio of the programmes, including the technical design of systems and services at an organisational and inter-organisational level, delivering at national scale.
  • Oversee the design, delivery and running of cyber operational capability, developing an enterprise architecture aligned with guiding principles and organisational risk appetite.
  • Research, identify, validate and adopt new security technology, architecture and methodology.
  • Lead engagement with customers across UK Government and the private sector on security risk and decision-making.
  • Communicate current and emerging threats, whilst designing security architecture to mitigate against them.

We are looking for a senior cyber security professional who combines deep technical architecture expertise with the confidence to operate at executive and government stakeholder level. You will bring a track record in enterprise security design, risk management and assurance across complex, multi-domain environments, and you are comfortable translating emerging threat landscapes into practical, proportionate security decisions.

Skills, Experience and Qualifications:

  • Referenceable, in-depth knowledge and experience in cyber security and IT, including business process design and cross-security domain approaches.
  • Understanding of IT networking and virtualisation technologies.
  • Ability to define architecture roadmaps and associated strategies, including assessment of IT systems, cloud offerings and security controls to provide an independent view of their compliance, effectiveness and alignment with business objectives and risk mitigation.

Here is an example of some of the Cyber Security Certifications expected for this role:

  • Certified Information Security Systems Professional (CISSP)
  • SABSA Chartered Security Architect (SCF)
  • Certified Information Security Manager (CISM)

Security Clearance:

This role requires SC clearance as a minimum with no restrictions, or the ability to obtain it.

Roles like this rarely come to market. The combination of technical complexity, national importance and genuine scope to shape security architecture from the ground up makes this an exceptional opportunity for the right person. If you are ready to move beyond incremental work and make a national difference please get in touch.

Where to Advertise Cloud Computing Jobs in the UK (2026 Guide)

Where to advertise cloud computing jobs UK in 2026: the specialist boards and channels that reach AWS, Azure, GCP and cloud-native engineering talent. The candidate pool is large relative to other deep tech disciplines but highly segmented — cloud architects, DevOps engineers, platform engineers, FinOps specialists and cloud security professionals each occupy distinct communities with different job search behaviours, certification profiles and salary expectations. General job boards reach a broad audience but struggle to differentiate between these disciplines, producing high application volumes but low candidate quality for specialist cloud roles. This guide, published by CloudComputingJobs.co.uk, covers where to advertise cloud computing 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.

Cloud Computing Jobs UK 2026: What to Expect Over the Next 3 Years

Cloud Computing Jobs UK 2026: salaries, hiring trends and the AWS, Azure and GCP skills shaping UK cloud careers over the next three years. Cloud computing is the infrastructure layer on which the modern digital economy runs — and the jobs market that has grown around it is one of the largest, most sustained, and most structurally resilient in the entire technology sector. But the cloud computing jobs market of 2026 looks quite different from the one that existed three years ago, and the next three years will bring further change at a pace that rewards those who understand the direction of travel. The migration phase that defined cloud hiring for much of the previous decade is largely complete for enterprise organisations. The question for most UK businesses is no longer whether to move to the cloud but how to operate, optimise, and secure what they have already built there — and how to integrate the wave of AI capability that is now being delivered primarily through cloud infrastructure. That shift has profound implications for which cloud skills are in demand, which roles are growing, and which are beginning to plateau. At the same time, new architectural patterns — multi-cloud, cloud-native, serverless, and the growing integration of edge computing with centralised cloud infrastructure — are creating entirely new categories of specialist expertise that employers are actively competing to hire. The cloud computing jobs market of 2026 is not contracting. It is evolving, and evolving in ways that create significant opportunity for job seekers who are building the right skills. This article breaks down what the UK cloud computing 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.
