Requirements
Have built or improved security in a development process: threat modeling, design reviews, and security tools in CI/CD (SAST, DAST, dependency scanning).
Experience with cloud infrastructure security: finding and fixing issues in AWS IAM and network configuration, Kubernetes (RBAC, network policies, workload permissions), and CI/CD pipelines (secrets handling, supply chain).
Experience implementing and operating automated attack detection and protection using technologies such as WAF, IDS/IPS, runtime application security, or SIEMincluding rule tuning, monitoring, alerting, and response to attacks such as SQL injection and XSS.
Experience in securing Node.js based application (Python or Go for tooling is fine too, but TypeScript is preferred.)
Either be conversational in Japanese or have a desire to do so (we will help).
Be located in, or be willing to relocate to, Japan (we will relocate).
Nice to haves
Experience testing or securing LLM-based features: prompt injection, jailbreaks, data leakage, or agent tool permissions.
Have led at least one full penetration test from start to finish scoping, testing, reporting, and confirming fixes against web applications, mobile apps, and APIs.
Have led a full certification audit (e.g., ISO 27001 / ISMS), ideally at a Japanese company: getting the controls in place, collecting evidence, and working directly with auditors.
Offensive security certifications (OSCP, OSWE) or bug bounty / CTF experience.
Compensation
7 to 11 million JPY annually.
