Développeur Senior Full Stack, Cyber

Our platform, Qostodian, helps large organizations discover, classify, govern, and remediate sensitive unstructured data across their most critical data sources without moving or copying the data. This zero copy architecture reduces exposure, preserves data sovereignty, and allows enterprises to secure data directly where it lives.

This matters because AI adoption is increasing the risk, complexity, and urgency of enterprise data security. Before organizations can safely deploy AI agents, copilots, retrieval systems, or automated workflows, they need to know where sensitive data lives, who and what can access it, and how to enforce controls at scale.

• Develop Microservice Oriented Architecture & build reusable components.
• Write well-designed, efficient, and testable code, using AI coding tools to accelerate implementation while maintaining code quality standards and performing unit and integration tests.
• Analyze performance and reliability to ensure that data is moving fast and accurately.
• Perform identification of code metrics and necessary analysis (code, requirements, system risk, and software reliability).
• Correct anomalies and problems as they arise.
• Test the implemented features to make sure all acceptance criteria are met
• Review code and provide guidance to other engineers to ensure that software is developed with maintainability, performance and security in mind.
• Participate in projects from the initial idea to launch.
• Advise the product owner on technological choices and decisions concerning developments.
• Contribute to the continuous improvement of development velocity, including AI-assisted testing, automated deployment pipelines, and LLM-augmented code review practices.
