Technology Principal (Security) in Newcastle upon Tyne

As a Technology Principal (Security), you'll work directly with our largest government and financial services clients to solve their most complex digital and security challenges, applying critical thinking to break down problems and identify practical solutions – with performance, scalability, security, and resilience built in from the start. You might start your week reviewing a detection engineering strategy for a major government department, spend time with a delivery team working through threat modelling on a live service, then present a secure cloud architecture to a client's senior leadership team.

Your background building and deploying enterprise‑scale digital services in regulated and security‑conscious environments means you can credibly advise on what works in practice, using systems thinking to understand how security decisions connect across the broader service and business context. Whether that's designing SIEM architectures and detection engineering capabilities across AWS, Azure, or Google Cloud, architecting zero‑trust models for hybrid and multi‑cloud environments, helping a bank modernise their data platform while meeting strict regulatory requirements, or embedding AI security governance and DevSecOps practices across a delivery lifecycle – you bring both strategic thinking and hands‑on experience to every situation.

You apply frameworks such as NCSC guidance, ISO 27001, and Cyber Essentials as practical tools that shape better outcomes, enabling effective security risk management, not compliance checklists.
