  • Develop, document, and maintain consistent secure architectural patterns with an emphasis on cloud security (AWS, Azure, GCP).
  • Implement threat-informed design principles, integrating zero trust architectures and defensive depth strategies to address security gaps and enhance resilience.       
  • Maintain alignment between security policies, enterprise architecture principles, and client expectations.

Risk and Threat Management

  • Conduct comprehensive risk assessments and threat modeling to evaluate existing or proposed architectures for vulnerabilities.
  • Provide actionable mitigation strategies informed by a risk-based approach and evolving threat intelligence data.
  • Participate in or support incident response initiatives, aiding in root cause analysis and the development of post-incident recommendations.

Client Engagement and Technical Leadership

  • Act as a trusted advisor to clients by engaging in technical discussions to inform strategic security decisions. 
  • Collaborate cross-functionally with development, operations, and engineering teams to validate that security controls are effectively implemented across the development lifecycle.
  • Deliver technical insights in presentations, workshops, and reports tailored to both technical and executive audiences.

Security Compliance and Governance

  • Engage in audits, assessments, and reviews to ensure delivery meets strict alignment with industry frameworks.
  • Provide clients with guidance on the implementation and enforcement of technical standards and cloud-specific security policies.
  • Maintain up-to-date knowledge of regulations and frameworks such as NIS2 and DORA to address compliance risks and initiatives.
  • Recommend improvements in security policies based on compliance evaluations and evolving risks.

Continuous Improvement and Innovation

  • Contribute to the development of security roadmaps by delivering expert recommendations tailored to each client’s security objectives.
  • Assess emerging technologies and threats, identifying opportunities to evolve architectural strategies through innovation and cutting-edge tools.
  • Participate as an SME in pre-sales activities, assisting in defining technical collateral that supports project delivery.
