We're building ReDuX-an AI-native platform that transforms legacy systems using agentic automation, domain knowledge, and cutting-edge LLMs. It's used to rewrite millions of lines of COBOL and Natural/Adabas into modern, cloud-native apps-powered by the latest in AI and cloud innovation.
As part of our core product team, you won't just integrate with AI-you'll build with it. You'll work directly on LLM workflows, integrating advanced prompt engineering, embeddings, and even LLM fine-tuning using techniques to make agents more accurate, adaptive, and human-aligned.
