This role sits at the intersection of engineering delivery and regulatory compliance. You will translate policy requirements (IM8 Reform, CSA CCOPv2) into implementable technical controls while working shoulder-to-shoulder with product and engineering teams in an agile delivery environment. Cloud & Infrastructure Security • Assess and validate security controls across IaaS/PaaS/SaaS environments, covering identity management, encryption, and network segmentation. • Govern security appliance policy and rule changes (WAF, DAM, Firewalls), including oversight of vendor operations and change management. Application Security • Triage application security findings against OWASP Top 10, reproduce and validate issues, and coordinate retesting with functional leads or delegates. • Ensure adherence to secure SDLC practices across the delivery lifecycle. Regulatory Compliance & Risk • Translate CSA Cybersecurity Act (CII CCOPv2) and WOG IM8 high-risk cloud requirements into actionable technical and process controls. • Log and assess GCSOC/GITSIR/agency advisories, determine impact, follow up with functional leads, and track to closure. • Manage Vulnerability Disclosure Programme findings end-to-end: triage, coordinate with functional leads, track remediation, and close. • Conduct security risk assessments and map technical controls to compliance requirements across relevant frameworks (ISO 27001, NIST, CIS benchmarks). • Support internal and external audits, including evidence gathering and coordination with auditors. Threat Modelling & Offensive/Defensive Operations • Conduct threat modelling with reference to the MITRE ATT&CK framework, scoped to the CII landscape. • Manage or support offensive and defensive operations, including VAPT, incident response, and incident management. • Participate in the design and solutioning of technical setups when new security requirements are introduced, using threat modelling outcomes to prioritize implementation. Stakeholder Engagement & Delivery • Liaise between CSA, Agency CISO stakeholders, and engineering teams — matching regulatory requirements with engineering approaches and design decisions. • Drive remediation through engineering teams, not just identify gaps. • Manage cross-functional security initiatives from requirements through deployment. • Leverage automation for compliance monitoring and evidence collection. • Establish and track KPIs for compliance posture and risk reduction. • Champion agile security practices within the delivery cadence. [What we are looking for] • Minimum 5 years of professional experience in cybersecurity engineering, with hands-on work in security operations, risk assessment, or compliance within cloud environments. • Working knowledge of Singapore-specific regulatory frameworks: WOG IM8 Reform and CSA CCOPv2 for Critical Information Infrastructure. • Hands-on experience with security technologies such as SIEM, CSPM, ASM, WAF, and vulnerability management tools. • Familiarity with cybersecurity frameworks and standards including OWASP, MITRE ATT&CK, ISO 27001, NIST, and CIS benchmarks. • Ability to communicate technical security concepts to policy and compliance stakeholders, and translate compliance requirements into engineering-actionable tasks. • Pragmatic decision-making: able to balance security requirements with delivery timelines and business needs. • Experience supporting audit cycles and producing compliance evidence. • Proficiency in at least one scripting language (e.g., Python, PowerShell, YARA) for automation and tooling. • Relevant certifications such as GCIH, GCFA, OSCP, CISSP, or AWS Security Specialty are advantageous. • Ability to conduct in-house VAPT is a strong plus. • Subject to the nature of your job role that might require you to be onsite during fixed hours.
