## About the Role

* Proven experience in the secure design and delivery of cloud services on AWS or Azure, evidenced by a cloud certification.
 * Deep architectural depth in at least one of AI/ML security, cloud security, M365 security or DevSecOps architecture.
 * Experience in application architecture, software development or infrastructure architecture.
 * Working knowledge of security standards and regulations including NCSC, ISO, NIST, SOC, PCI and GDPR.
 * Practical command of network security (OSI, TCP/IP), web application security (OWASP) and cryptographic controls (PKI, TLS).
 * Architecture or security design work you have personally owned and can defend in detail under technical challenge.

Desirable:

 * Identity and access management experience, including authentication and authorisation products and patterns.
 * Current UK security clearance, or clear eligibility to obtain it.
 * Zero Trust architecture experience, or architecture-as-code approaches such as C4.
 * Involvement across the full security lifecycle including governance, operational security and supply chain security.
 * Penetration testing certifications such as OSCP, CREST or TIGER.
 * Prior experience mentoring or leading security engineers.
 * Use of AI tooling within your own daily working practice.

## Description

You will own the secure design of new cloud services from first principles through to delivery, working embedded with agile teams rather than reviewing their work from a distance. Day to day that means threat modelling, making architectural calls that balance security against cost and usability, getting hands-on with the tooling to verify what you have designed actually holds, and explaining the trade-offs to stakeholders who need to make decisions on them. You will also mentor engineers and less experienced architects as the team grows around you., * Own the secure design of new cloud services and solutions from first principles through to delivery.

 * Identify security weaknesses in existing system designs and recommend mitigations that balance cost, risk and usability.
 * Work embedded within agile delivery teams to build good security practice into the development lifecycle.
 * Run threat modelling sessions and translate the output into design decisions engineers can implement.
 * Apply network, application and cryptographic controls appropriately across the platforms you design.
 * Test the security of software and infrastructure using appropriate tooling rather than relying on documentation alone.
 * Mentor engineers and less experienced architects, supporting their technical development.
 * Explain security decisions and trade-offs clearly to both senior stakeholders and development teams.
