Security, Governance & Compliance

• Maintain and enhance security controls across enterprise cloud, data, and AI platforms.
• Review identity and access management, platform permissions, and security configurations.
• Implement security baselines, governance standards, and cloud security guardrails.
• Ensure platform compliance with enterprise architecture, cybersecurity, data governance, and regulatory requirements.
• Support security audits, risk assessments, vulnerability remediation, and compliance activities.
• Collaborate with security and governance teams to strengthen platform security and operational controls.

Vendor Management & Technical Governance

• Provide technical oversight and engineering assurance for vendor-delivered platform services.
• Review technical architecture, solution designs, implementation quality, and operational readiness.
• Ensure vendor deliverables align with enterprise architecture standards and platform governance requirements.
• Coordinate technical remediation, platform optimisation, and risk mitigation activities.
• Serve as a technical escalation point for complex platform engineering issues.
• Participate in architecture reviews, engineering governance discussions, and technical decision-making.

Technical Advisory & Stakeholder Collaboration

• Provide technical guidance to Data, Infrastructure, Security, Product, and Application teams.
• Support project teams in adopting standard platform services, engineering practices, and integration patterns.
• Collaborate with internal stakeholders, external vendors, and cloud service providers.
• Contribute to platform roadmap planning, technology evaluations, and operational readiness assessments.
• Recommend engineering improvements to enhance platform scalability, security, reliability, and operational efficiency.

Requirements

• Minimum 7 years of experience in platform engineering, cloud infrastructure, DevOps, or enterprise platform operations.
• At least 5 years of hands-on experience with Microsoft Azure.
