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 Senior 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.

Key responsibilities of the role include:

• 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

Who are we looking for?

You are someone who can hold your own technically and is not afraid to have a direct opinion.

The environment is fast, the engineers are exceptionally sharp and the problems are often non-standard. You will need to be credible in rooms where people challenge assumptions as a matter of course, and confident enough to push back when security genuinely matters.

What we are looking for:

• 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

Useful but not essential:

• Red, blue or purple team experience
• Financial services background
• Experience with large-scale compute infrastructure or research environments

What matters more than your CV:

• You are genuinely curious about how things work
• You form views and can defend them, but update when presented with better information
• You would rather solve an interesting problem than follow a process
• You can be direct without being difficult

Why join us?

• Highly competitive compensation plus annual discretionary bonus
• Lunch provided (via Just Eat for Business) and dedicated barista bar
• 30 days’ annual leave
• 9% company pension contributions
• Informal dress code and excellent work/life balance
• Comprehensive healthcare and life assurance
• Cycle-to-work scheme
• Monthly company events
