Are you an experienced Senior IAM Engineer or Identity and Access Management (IAM) Lead looking to advance your career in cybersecurity within the financial technology industry?

Join a global financial technology company operating at the intersection of investment banking, trading technology, and digital asset infrastructure.

As a Senior IAM Engineer / IAM Lead, you will play a critical role in strengthening enterprise identity security, privileged access controls, cloud security, and identity governance across the organization.

You will design, implement, and manage Identity and Access Management (IAM) solutions, including Single Sign-On (SSO), Multi-Factor Authentication (MFA), Privileged Access Management (PAM), and Identity Governance and Administration (IGA).

The role combines hands-on security engineering with technical leadership, automation, and cross-functional collaboration. You will work closely with cybersecurity, infrastructure, engineering, and global technology teams to improve security controls, reduce identity-related risks, and build scalable access management solutions.

You will also leverage cloud technologies, scripting, and Infrastructure as Code (IaC) to automate IAM processes and enhance operational efficiency.

Based in Tokyo, this is an excellent opportunity for an experienced cybersecurity professional with strong Japanese and English communication skills to contribute to a fast-growing international financial technology organization.
