Security Engineer

We’re looking for a Senior Product Engineer to join a technology company developing AI- and data-driven products for financial institutions.

This is not a traditional internal security or compliance role. We’re looking for an engineer who can bring cybersecurity knowledge into product development and turn security expertise into scalable software.

You’ll work on features that analyze source code, system configurations, libraries, and other technical information to identify and visualize vulnerabilities and security risks.

🔥 Key Responsibilities

・Design and develop products for financial institutions

・Translate security challenges and business requirements into technical solutions

・Develop features to analyze and visualize vulnerabilities and security risks

・Build capabilities for analyzing source code, libraries, configurations, and system information

・Design and implement security assessment logic

・Develop security analysis features using Generative AI and AI agents

・Contribute to technology selection and architecture design

・Collaborate with Product Managers and security experts

🔍 Requirements

・3+ years of software development experience

・Solid foundational knowledge of cybersecurity

・Ability to translate security challenges into software requirements

・Experience working across the full development lifecycle, from design and implementation to operations

・Business-level English or above

・Valid work authorization in Japan

What makes this role interesting

Rather than simply conducting security assessments or providing consulting, you’ll have the opportunity to turn security expertise itself into software.

This could be a great fit for someone who wants to work at the intersection of cybersecurity and product development, or who is interested in applying Generative AI to real-world security products.

If you’re interested, feel free to send me a DM!
