We are seeking a highly skilled and motivated Senior AI/ML Engineer to join our dynamic team and take part in creating a new product. 

The team is working on an AI Agent to develop and  support business processes for different business areas.

About the project:This project is building an AI platform that helps companies develop complex software faster and with fewer errors.Instead of writing requirements, documentation, and validation rules manually, the platform does it using AI.It turns a product idea into detailed, ready-to-implement specifications — and keeps them in sync with tests and validation.It’s especially valuable for large organizations that work under strict regulations (like finance or healthcare), where precise documentation is critical.

Requirements:

• Experience: Demonstrated experience of at least 5 years in developing AI/ML solutions with a focus on LLM and LLM frameworks (e.g. LangChain). Strong knowledge and practical experience in Generative AI, Interactive Chatbots, Graph databases. Experienced in Python, async input/output, multiprocessing, parallel processing.
• Data Processing: Experience in preprocessing and handling large-scale, unstructured text data, and the ability to perform data analysis and validation.
