About the Role

This role sits within the Security Advisory function, reporting to the Security Advisory Manager and working alongside a team of experienced security architects and security engineers. As a Security Architect you will provide security architecture guidance across a broad technical landscape: public cloud, an extensive in-house compute environment and everything in between. The problems vary. Some are greenfield, some are legacy and many are novel enough that established playbooks do not apply.

Responsibilities

Providing technical security architecture guidance across projects and programmes.
Assessing the security of in-house and third-party applications, services, infrastructure and processes.
Threat modelling, particularly for complex, high-value systems.
Reviewing engineering designs and recommending practical security improvements.
Evaluating compensating controls and articulating residual risk when ideal solutions are not achievable.
Identifying audit points and indicators of compromise.
Improving security processes to match the pace of the organisation.
Escalating decisions that exceed risk appetite appropriately.

Requirements

Demonstrable experience in security architecture.
Practical threat modelling skills applied to real systems.
Cloud security experience: AWS, Azure or equivalent.
The ability to absorb complex technical problems quickly and provide clear, defensible guidance.
Experience reviewing engineering designs and improving security outcomes.
Strong communication skills, particularly the ability to be precise and direct with highly technical teams.
Genuine curiosity about how things work.
A preference for solving interesting problems over following a process.
