About the Role

Binance is seeking a Chief Information Security Officer to lead the information security function across our Korea operations during a critical period of regulatory growth. This is a high-impact leadership role requiring someone who can bridge enterprise-grade cloud security with the distinct regulatory landscape of Korea. The CISO will be the primary security advocate internally and with regulators, owning both the technical security posture and the compliance narrative.

Responsibilities

Regulatory & Compliance Leadership

• Own end-to-end security certifications — from gap assessment through to audit readiness and approval
• Serve as the primary liaison to Korean financial regulators (FSC, FSSC, KISA) on all security and data protection matters
• Translate regulatory requirements into actionable security controls and communicate these effectively to global Binance teams
• Arrange and lead annual IT security risk assessments

Security Strategy & Operations

• Define and execute the information security strategy for Korea, aligned with global security standards
• Oversee cloud security architecture and ensure controls meet both global policy and local regulatory expectations
• Lead incident response, threat modeling, and vulnerability management programs across both markets
• Manage InfoSec teams, including hiring, mentoring, and performance management

Internal & Cross-functional Collaboration

• Partner closely with global CISO office, engineering, legal, and compliance teams
• Advocate for security requirements at the global level — push back when needed, align when appropriate
• Work with external consultants and third-party auditors supporting certification and audit cycles in both markets

Stakeholder Communication

• Report to leadership and maintain transparency on security posture, risk, and regulatory timelines
• Present risk assessments and security updates

Requirements

• Bachelor's degree or higher in Information Technology, Cyber Security, or a related field
• 10+ years of information security experience, with at least 3–5 years in a senior leadership role (CISO, Head of Security, or equivalent)
• Hands-on experience with ISMS or ISMS-P certification in Korea — ideally as the accountable owner through a successful audit cycle
• Deep familiarity with Korean financial/digital asset regulatory requirements (FSC guidelines, PIPA, KISA standards)
• Strong understanding of cloud security and modern enterprise security architectures
• Proven ability to collaborate across functions — you work with engineering, compliance, and legal, not around them
• Bilingual English and Korean is required to be able to coordinate with overseas partners and stakeholders
• Strong ownership mindset — you drive outcomes, not status updates

Strongly Preferred

• Prior experience at a financial institution, crypto exchange, or fintech
• Experience managing a security function during a regulatory examination or enforcement period
• Experience engaging directly with regulatory bodies
• Relevant certifications: CISSP, CISM, CISA, ISO 27001 Lead Auditor, or equivalent

Why Binance

• Shape the future with the world’s leading blockchain ecosystem
• Collaborate with world-class talent in a user-centric global organization with a flat structure
• Tackle unique, fast-paced projects with autonomy in an innovative environment
• Thrive in a results-driven workplace with opportunities for career growth and continuous learning
• Competitive salary and company benefits
• Work-from-home arrangement (the arrangement may vary depending on the work nature of the business team)
