You will work closely with engineering, delivery, and governance teams to define and document architectural patterns, lead threat modelling activity, and provide hands-on guidance across cloud workloads and infrastructure.
Key Responsibilities- Design and own end-to-end security architecture across AWS and Azure cloud environments, ensuring solutions are secure by design and aligned to programme objectives.
- Develop and maintain architectural artefacts including HLDs, LLDs, and security design documentation in line with standards and wider government frameworks.
- Lead threat modelling and risk assessment activities across cloud workloads, identifying security gaps and providing actionable remediation guidance.
- Ensure adherence to relevant security frameworks including NCSC Cyber Essentials, NIST, ISO 27001, and the Government Security Classification (GSC) policy.
- Engage with technical and non-technical stakeholders to communicate security requirements, influence design decisions, and support governance and assurance processes.

- Strong working knowledge of security frameworks such as NIST CSF, ISO 27001, NCSC guidance, and experience applying these within regulated or public sector environments.
- Ability to produce high quality security design documentation and architecture artefacts, with experience working within structured delivery methodologies (Agile or Waterfall).
- Experience conducting threat modelling, risk assessments, and security reviews across complex cloud native or hybrid environments.
- Excellent stakeholder engagement and communication skills, with the ability to translate technical security concepts for non-technical audiences across large programme teams.
