️ Security Engineering & Architecture:

* Implement and harden network and endpoint defenses including firewalls, IDS/IPS, and Zero Trust models.
* Develop secure authentication systems and manage encryption protocols.
* Champion secure CI/CD pipelines and API security across development teams.
Standards, Compliance, and Best Practices:

* Participate in red/blue team simulations and internal security assessments.
* Provide expert-level guidance on secure coding, DevOps security, and threat prevention strategies.
Candidate Profile:
