Job Description

Context

As part of a mission for one of our clients, we are looking for a Senior Cloud Security Engineer to work on the securing and remediation of critical Cloud environments.

Several security audits have identified vulnerabilities and configuration gaps. The objective of the mission is now to move from observation to correction: analyze vulnerabilities, understand their impacts, and implement remediations directly within the environments.

We are therefore looking for a highly operational profile, with a strong cybersecurity culture, capable of intervening in both Build and Run.

Missions

• Analyze vulnerabilities and security gaps resulting from audits and implement technical remediations.
• Administer, secure, and harden Azure and Microsoft 365 environments.
• Secure identities and access under Entra ID: Conditional Access, MFA, PIM, Identity Protection, RBAC, and privileged accounts.
• Secure technical identities: Service Principals, Managed Identities, App Registrations, and secrets.
• Deploy and maintain security policies via Azure Policy.
• Intervene on Harness CI/CD pipelines and secure pipelines, permissions, Service Connections, and secrets.
• Design and maintain infrastructures via Terraform / ARM.
• Administer and secure OpenShift / Kubernetes environments: RBAC, Network Policies, images, containers, and access.
• Challenge technical choices in light of cybersecurity risks.

Qualifications

Required Profile

• 5 to 10 years of experience in Cloud, infrastructure, DevOps, and/or security.
• Solid operational expertise in Azure and Entra ID.
• Concrete experience with Terraform, CI/CD, and OpenShift/Kubernetes.
• Good mastery of Cloud security issues, IAM, hardening, privilege management, secrets, and vulnerability remediation.
• Ability to understand a security finding, identify its cause, and directly implement the correction.
• Autonomous, pragmatic, and problem-solving oriented profile.
• Fluent English is essential.

The Key Point

We are not looking for an exclusively audit/GRC profile, nor a Cloud expert without a security culture.

We are looking for a senior Cloud/DevOps engineer with true cybersecurity DNA, capable of transforming findings from an audit into concrete remediation actions within the environments.

Additional Information

🤲 Regardless of your degree or background, we are primarily looking for skills, values, and motivation.

Our programs in favor of education and inclusion allow us to integrate profiles from diverse backgrounds, and we are extremely proud of this because we are convinced that this is how our team is enriched; diversity is an invaluable source of creativity and innovation.
