仕事内容Job description [1. Advancing Safe CI/CD Pipelines to Support AI-Driven Development Including Non-Engineers]
At our company, we are promoting AI-driven development company-wide, including non-engineers. As the number of people involved in development expands, the volume of changes and release frequency are increasing explosively.
To support this change, we will advance our CI/CD pipeline by incorporating security and quality guardrails, aiming to achieve a state in which anyone's changes can be delivered safely and seamlessly to the production environment.
[2. Building an AI-Driven Security Verification Platform (Application of Shadow Persona Technology)]
We will extend the know-how from AI agent-based development that our company practices (such as Shadow Persona Skill) into the QA and security domains, and build cutting-edge QA/security pipelines, including automatic detection of E2E regressions before production and AI-driven internal vulnerability assessments that simulate diverse attack patterns.
[3. Ensuring Proactive High Availability Based on SLI/SLO]
Leveraging our integrated monitoring platform, we will promote appropriate SLI/SLO definition and operation across all products.
We will shift from a reactive model (responding after failures occur) to a proactive operations model (early warning detection, automated recovery, and data-driven capacity planning).
[4. Optimization and Re-architecting of Cloud-Native Environments]
With an eye toward the future business expansion, platformization, and data integration infrastructure development of "CAREECON Plus," you will take a central role in resolving existing technical debt while driving architecture redesign and infrastructure cost optimization.
[5. Establishing a CSIRT Organization and Building an Automated Security Response Platform]
We will build a system that automates the detection, initial response, and first-stage investigation reporting of security incidents, with humans responsible for decisions.
We will establish a CSIRT while involving executive management, and build resilience against cyber threats through both organizational and systemic measures.
