IT Security Architect, FS
London, City (Hybrid)
Highly competitive salary with bonus and FS benefits
A leading global financial services firm is building out its security architecture function and looking for a strong Security Architect to join a lean, fast-moving team at a genuinely interesting moment. The firm is mid-transformation: cloud migration, a Zero Trust programme, and a growing AI security agenda. There is real work to do, and real scope to shape how security architecture is delivered across the business.
The role
You will conduct security design reviews end to end, perform threat modelling, author security standards and patterns, and provide architecture consultancy to project teams across the business. You will build deep knowledge of a specific business division while remaining part of a central, shared team. This is not a governance role. You will need to know your technology well enough to have real conversations with engineers and shape solutions, not just review them.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What they are looking for
The ideal profile sits between pure theorist and hands-on practitioner. Close to technology, technically credible, and operating confidently at architecture level.
Core requirements:
- Currently working as a Security Architect, not transitioning from SecOps or engineering
- Strong Azure and Microsoft cloud knowledge, including identity, networking, and workload protection
- Solid IAM background covering federation, SSO, MFA, and privileged access
- Experience in a regulated environment, either financial services or consultancy with FS clients
- Proven threat modelling and security design review experience, with the ability to write clear security standards
Get help with your application
Your very own career expert that helps elevate your application to the next level.
Strong differentiators:
- Awareness of AI and LLM security risks (a live priority here, not a future one)
- Network segmentation, Zero Trust, and SASE/SSE experience, SABSA certification
The environment
This firm moves fast. If you are used to a large architecture team where everyone owns a small slice of a long process, this probably is not the right fit. If you want breadth, real ownership, and the chance to build something properly, it is worth a conversation.
“It took my CV and asked me questions relevant to understanding what kind of jobs to suggest for me. Suggestions were almost perfect. Jobs were exactly what I’ve been looking for.”
