Security Architect

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., * Providing technical security architecture guidance across projects and programmes

• Assessing the security of in-house and third-party applications, services, infrastructure and processes

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.

• 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

• 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
