job details

Hands-on ownership of Azure AD/Entra ID Security and O365 Conditional Access design and implementation.
End-to-end ownership of cloud and infrastructure security as part of a holistic infrastructure operating model.
Owned cloud and infrastructure security as a core component of the end-to-end infrastructure operating model to ensure seamless security integration.

about the company ...

We need a potential infrastructure leader who builds security into the very DNA of our systems.

We are looking for a Senior Infra Security Engineer who "owns" the environment. You aren't just managing tools; you are designing and implementing the secure foundation of our global infrastructure.

about the job

Take full ownership of the infrastructure security lifecycle from initial architectural design and "shift-left" deployment to day-to-day operational excellence.
This is not a "support" task. You will lead the design and hands-on implementation of our Azure AD / Entra ID ecosystem, including complex O365 Conditional Access policies and IAM frameworks.
Build and secure scalable Azure and AWS environments, ensuring every VNET, Firewall, and PaaS service is hardened against modern threats while optimized for cost and performance.
Drive the transition to a modern operating model by automating security controls using Terraform or similar tooling, ensuring compliance is "baked in" by default.
Beyond prevention, you will own the technical execution of Disaster Recovery and Business Continuity plans, ensuring our global operations remain uninterrupted.

skills and experience required
At least 8+ years of experience, but more importantly, a track record of owning infrastructure. You can describe the "why" and "how" behind the systems you’ve built.

Hands-on expert in Microsoft Azure/AWS, with specific, demonstrable experience in securing Entra ID (Azure AD) and designing sophisticated Conditional Access workflows.

Understand how a firewall change affects the application layer and how an IAM policy impacts the developer workflow.

You can bridge the gap between high-level roadmaps and low-level configuration, communicating effectively with both the C-suite and the engineering team.

whats an offer
The permanent opportunity for a Senior Infrastructure Security Engineer, will pay a salary range of $ 8,500 - $ 9,800 plus benefits. This opportunity offers hybrid working arrangement.
