Job description

Security architecture assessments and consultations are required as a prerequisite to the go live in order to comply with OH Policies and standards. Security architecture assessments ensure compliance of product/project architectures with approved security architectures standards and cloud decision records prior to the project go-live date. The Sr. Security Architect ,will support the project influx and ensure the mandatory security architecture assessment is done in a timely manner that doesn’t intervene with the project’s go-live dates.

Required Skills:

• 10 or more years of experience in IT security principles, practices, technologies, programs, and procedures with a solid knowledge of cloud architecture and security controls.
• Certifications in in any of the following cyber security and cloud security architecture (e.g., CISSP-ISSAP, CCSP, GDSA)
• Certifications in any of the following are an asset. ArchiMate, TOGAF, SABSA, Zachman

Responsibilities:

• Develop and maintain security reference architectures, network diagrams and other guidelines to support the policies and standards, enabling the delivery of target state enterprise-level Information Security capabilities, and reducing the risk of siloed and redundant solutions.
