Information Security Technical Lead
📍 London (City) – Hybrid
Own, shape, and lead enterprise security within a high-impact, technology-driven insurance environment. We’re partnering with a well-established insurance organisation investing heavily in digital transformation and security capability. They are now looking to hire an Information Security Technical Lead to take full ownership of their end-to-end security function.
This is a hands-on leadership role where you will define strategy, lead a team, and actively engineer and enhance security controls across a complex, business-critical environment.
The Opportunity
This is not a governance-heavy or purely advisory role. You will:
- Own and deliver the security roadmap across core platforms and systems
- Lead and develop a team of security engineers
- Act as the senior escalation point for security incidents and response
- Work within a modern Microsoft/Azure environment, driving improvements across M365 security and identity
- Play a key role in shaping how security supports both internal operations and external services
You’ll sit at the intersection of infrastructure, operations, and stakeholder engagement—combining deep technical expertise with real business impact.
What You’ll Be Doing
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.
