Summary

As Lead Security Architect you will direct secure architecture across a portfolio worth hundreds of millions of pounds. Working with product owners, delivery managers and enterprise architects, you will ensure every new or changed service conforms to Home Office and NCSC standards while enabling rapid, user centred delivery.

You will analyse emerging threats, advise on proportional mitigations, and produce or tailor reference patterns covering identity, network segmentation, container security, data protection, and monitoring. By modelling risks with frameworks such as ISO 27005, NIST, or STRIDE, you will justify design choices to technical and non technical audiences and document them for re use. You will champion “secure by default” in agile pipelines embedding IaC scanning, SAST/DAST, SBOM and cloud native guardrails so security becomes a quality attribute owned by delivery teams.

Through communities of practice and one to one coaching, you will nurture SEO architects and engineers, acting as escalation point for complex design decisions. Finally, you will cultivate relationships with external suppliers, government peers and industry forums to import good practice and influence future standards, ensuring Home Office services remain resilient, cost effective and compliant.

Due to business requirements this post is available on a full time/flexible working basis. Where business needs allow, some roles may be suitable for a combination of office and home-based working. Where this is the case, employees will be expected to spend a minimum of 60% of their working time in the office. Applicants can raise any queries to the email address at the bottom of the advert.
