Cyber Security AI Engineer

The Opportunity

Join the Hitachi Energy Cybersecurity Operations team as a Senior Full Stack Developer specializing in GenAI/ML and become part of a new engineering initiative focused on solving real-world cybersecurity challenges. As cyberattacks grow in scale and sophistication, our Cyber AI Engineering Hub is tasked with rapidly designing and building AI-driven solutions that transform how cybersecurity teams operate. In this role, you will take ideas from early prototypes to production-ready systems that directly improve incident response, threat detection, and other core cybersecurity functions. If you thrive on innovation, rapid iteration, and applying advanced AI techniques to meaningful operational problems, this role offers a unique opportunity to make a significant impact.

How You Will Make an Impact

• Design, build, and deploy production-grade GenAI applications using LLM APIs
• Own end-to-end feature delivery, including backend development in Python, API design, and UI integration
• Implement RAG pipelines, agentic workflows, and tool-calling in operational cybersecurity systems
• Integrate AI workloads with log platforms, data lakes, automation workflows, and security tools
• Build and maintain REST APIs (FastAPI) to support scalable AI services
• Engage with cybersecurity stakeholders to refine requirements and demonstrate capabilities
• Ensure reliability, scalability, and maintainability of deployed AI software solutions

• Strong proficiency in Python and backend engineering for production systems
• Hands-on experience designing and building REST APIs (FastAPI, Flask, or Django)
• Practical experience integrating LLM APIs (OpenAI, Claude, Gemini, etc.) and applying RAG, prompt engineering, and agent orchestration
• Experience working in cloud environments (Azure preferred) and familiarity with DevOps tools
• Strong communication skills and fluency in English
• Advantageous: Experience with PostgreSQL/MongoDB, Docker, CI/CD, Azure services, SOAR platforms, or cybersecurity operations (SOC, detection engineering, incident response).
• Frontend engineering experience is a plus
