We are looking for cloud security professionals to support cybersecurity operations across Azure, AWS and GovTech cloud environments. You will help assess cloud security posture, support system go-live readiness, administer approved access changes and coordinate remediation of security findings.

You will work with PUB Cybersecurity, system owners, infrastructure teams, application teams and vendors to validate issues, recommend corrective actions and maintain clear, auditable records.

What you’ll do

• Support cybersecurity readiness checks for new systems, technology refreshes and migrations. Review submission materials for completeness and track outstanding go-live requirements.

• Review and validate cloud security posture findings from platforms such as Microsoft Defender for Cloud, AWS Security Hub and GovTech CloudSCAPE.

• Assess cloud configuration issues involving identity and access, privileged access, network security, encryption and other security controls.

• Recommend remediation actions and coordinate with infrastructure and application teams to track findings through to documented closure.

• Process approved Azure RBAC and cloud access requests, maintain audit records, and follow up on temporary or elevated access.

• Support compliance assessments, remediation evidence reviews and risk assessment documentation.

• Maintain findings registers, readiness trackers, reports, procedures and supporting documentation.

• Escalate high-risk, overdue or disputed findings for assessment and direction.

What we’re looking for

• A diploma or degree in Cybersecurity, Computer Science, Information Technology, Cloud Engineering or a related field, with relevant practical cloud security experience.

• Hands-on experience administering or supporting Microsoft Azure environments, including Azure RBAC, Entra ID concepts, Azure Policy, privileged access and secure resource configuration.

• Ability to provide technical support on AWS security configurations.

• Working knowledge of Microsoft Defender for Cloud or a similar cloud security posture management tool.

• Understanding of cloud security findings, secure configuration, vulnerability remediation, compliance requirements and remediation evidence.

• Ability to interpret architecture diagrams, security assessment reports and technical remediation responses.

• Clear communication skills and disciplined documentation, with the ability to work with technical teams, vendors and cybersecurity stakeholders.

Additional experience that would be useful

• Experience with GovTech GCC/GCC+ environments or CloudSCAPE.

• Experience with AWS Security Hub, Azure Log Analytics Workspace or Azure Workbooks.

• Experience supporting cybersecurity go-live, VAPT, hardening, System Security Plan or risk assessment workflows.

• Azure security or administration certification, such as AZ-500. AWS, CISSP, CCSP, CISM or CRISC certifications are also advantageous.

• Experience with scripting or automation for posture assessments, findings validation, reporting or remediation tracking.

Role levels

We have openings at Associate and Senior levels. The scope of responsibility will be matched to experience, with senior hires expected to take greater ownership of complex technical reviews and stakeholder coordination.

This is a hands-on operational support role. It does not include cybersecurity alert monitoring or incident response. The role is primarily onsite at designated PUB premises, with occasional support at other PUB sites. Support outside normal office hours may be required for scheduled maintenance, production cutovers or urgent remediation, subject to approved arrangements.
