Develop automation to manage security tools and integrate security standards in workflows (Infrastructure-as-Code, SDLC…).

Build and feed relevant KPIs, SLAs and reporting to meet business objectives.

Provide deep technological expertise, guidance, recommendations and standards on security at different layers (networks, systems, Cloud, endpoints, applications…) in a hybrid environment (Cloud/Onsite).

Ensure that business requirements are understood and adhered to as well as security risks and standards in new and existing infrastructure are properly understood and mitigated.

Assist in response to due diligence and internal / external security audit requests.

Knowledge in system, network, DB and Cloud admin (Linux, TCP/IP, PGSQL, AWS..).

Knowledge in web application security and SSDLC (OWASP, Git, CI/CD…). Developer and/or pentesting skills would be a good differentiator.
