Security Engineer/ Admin Microsoft, Azure, OWASP

Position Overview
We are seeking a highly skilled and proactive Security Administrator to join our technology team. This is a critical, hands- on role responsible for securing our entire digital footprint, from internal corporate systems to client- facing applications, including our proprietary solutions.
You will be responsible for monitoring our security posture, responding to threats, and proactively hardening our systems. This position requires technical knowledge of both Microsoft environments and common open- source security platforms, along with a good understanding of application security. You will work hand- in- hand with our engineering team to integrate security into all aspects of our technology and will provide supervisory guidance on security- related tasks, reporting directly to the Head of Technology.
The ideal candidate is a versatile, technology- agnostic problem solver. You must be able to analyze complex environments, design robust security solutions, and execute the necessary configurations. A key part of this role is the ability to propose the right solution for the business, whether it is a proprietary, commercial product (like Microsoft&039;s) or an open- source alternative.
Key Responsibilities
Analysis & Monitoring:

Conduct regular vulnerability assessments and risk analyses across all corporate and client- front systems.
Analyze the security of our applications, identifying potential vulnerabilities in architecture and configuration, and working with engineering to prioritize remediation.
Proactively monitor and analyze security alerts from our security tools to detect, investigate, and respond to potential threats.

Solution Design & Proposal:

Design secure configurations for new and existing systems and applications.
Evaluate the current security posture and propose practical, effective solutions and configuration changes to mitigate risks.
Evaluate and recommend new security technologies, comparing commercial and open- source solutions to determine the most effective and cost- efficient way to meet security objectives.

Execution & Configuration:

Install, configure, and manage a diverse range of security tools, including selected open- source platforms (SIEMs, log management, vulnerability scanners...).
Execute remediation plans for identified vulnerabilities, including patch management and system reconfiguration.
Lead the hands- on configuration, implementation, and hardening of our Microsoft ecosystem (Microsoft 365, Entra ID, Azure, Defender Suite, Intune).

Supervision & Collaboration:

Work closely with the Head of Technology to develop, document, and maintain security policies, standards, and procedures.
Liaise with the engineering team to ensure security is a core component of all new product development and system rollouts.
Provide technical supervision and guidance to engineering and IT team members on the correct implementation of security controls and best practices.
Act as the primary technical point of contact for security incidents, coordinating the response between the technology team and management.
