You will be CP Axtra's subject matter expert on ISO 27001, responsible for the practical implementation and continual improvement of the Information Security Management System. Where the GRC Department Manager sets the strategic direction, you make it happen — maintaining the ISMS documentation, conducting internal audits, managing the risk assessment process, and ensuring the organisation is always audit-ready.

Your day-to-day involves working across every part of the business that touches information security — from IT infrastructure to HR onboarding processes to vendor management. You'll conduct internal audits that find real gaps (not just confirm what's already known), drive corrective actions to closure, and continuously improve the ISMS based on changing business needs, new threats, and lessons learned from incidents.

Key Responsibilities:

·       Maintain and continuously improve the ISMS documentation — policies, procedures, SOA (Statement of Applicability), risk treatment plans, and operational procedures aligned to ISO 27001:2022

·       Plan and conduct the annual internal audit programme — schedule audits across all ISMS scope areas, conduct audits (or manage internal/external auditors), and produce findings with specific evidence

·       Manage the ISO 27001 certification lifecycle — prepare for surveillance audits and recertification, coordinate with the certification body, manage audit logistics, and track NCR (non-conformity report) resolution

·       Conduct and facilitate information security risk assessments using the organisation's risk methodology — identify threats, assess likelihood and impact, and recommend risk treatment options

·       Drive corrective and preventive actions (CAPA) to closure — track remediation progress, validate effectiveness, and escalate overdue items to the GRC Department Manager

·       Manage the security policy review cycle — ensure all policies and procedures are reviewed at defined intervals, updated to reflect changes, and communicated to relevant stakeholders

·       Support business units in understanding and implementing ISMS requirements — translate ISO 27001 controls into practical operational guidance

·       Maintain the risk register and treatment plans — ensure risk assessments are current, treatment plans are progressing, and risk acceptance decisions are properly documented

·       Produce ISMS performance metrics and management review inputs — control effectiveness, audit findings trends, risk posture changes, and improvement opportunities

·       Coordinate with other compliance frameworks (PDPA, PCI-DSS) to identify synergies and reduce duplicate effort across compliance programmes

Requirements

TECHNICAL REQUIREMENTS

·       ISO 27001:2022 framework: Deep understanding of clauses 4-10, Annex A controls, and SOA management

·       Risk assessment tools and methodologies: ISO 27005, risk matrices, risk register management

·       Audit management: Internal audit planning, evidence collection, finding documentation, CAPA tracking

·       Policy and document management systems: Version control, review workflows, distribution tracking

·       Integration knowledge: Understanding of how ISO 27001 controls map to technical implementations (firewalls, access controls, logging, encryption)

MUST-HAVE REQUIREMENTS

These are non-negotiable. If you do not meet all of these, this role is not the right fit.

·       5+ years in information security with at least 3 years focused on ISO 27001 implementation and maintenance

·       ISO 27001 Lead Auditor or Lead Implementer certification — this is non-negotiable for the role

·       Hands-on experience conducting internal audits — you've planned audit programmes, conducted audits, and written findings that led to real improvements

·       Practical experience with information security risk assessment methodologies (ISO 27005 or equivalent)

·       Strong documentation and communication skills — able to write clear policies and procedures, and explain ISMS requirements to non-security staff

·       Fluent in Thai for internal audits and stakeholder communication; reading/writing English for ISO standards and documentation

NICE-TO-HAVE

These will set you apart from other candidates:

·       Experience with the ISO 27001:2022 transition — understanding of the new Annex A control structure and Annex SL alignment

·       Familiarity with ISO 27701 (privacy), ISO 22301 (BCM), or PCI-DSS — multi-framework compliance experience

·       Experience with GRC or ISMS management tools (e.g., OneTrust, Vanta, or similar)

·       Background in IT operations or system administration before moving into GRC — understanding of how controls work in practice

·       CISM, CRISC, or additional GRC-relevant certifications
