• Lead implementation and configuration of enterprise security tooling, ensuring alignment with architectural standards.
• Develop and maintain security policies, standards, and methodologies to support consistent architecture practices.
• Monitor emerging threats and technologies, providing proactive recommendations to strengthen security posture.
• Evaluate and onboard third-party solutions, ensuring secure integration and compliance.
• Provide strategic guidance on encryption, secure protocols, and infrastructure hardening.

Qualifications

• Excellent analytical, collaboration, and stakeholder engagement skills.
• This role is not eligible for immigration sponsorship.

Preferred Qualifications

• Experience with Zero Trust and large-scale infrastructure transformation initiatives.
