Senior AI / LLM Python Developer
About the Project
You will join an international team working on an AI-driven compliance intelligence solution. The system leverages Large Language Models (LLMs) to analyze documents, standards, and regulations in order to:
generate compliance reports,
identify gaps and risks,
recommend remediation actions.
This solution supports organizations operating in highly regulated environments by enhancing decision-making processes through AI.
We are looking for experienced engineers to strengthen the AI/LLM layer and co-create the system architecture.
Responsibilities
Design and develop LLM-based solutions (including RAG, fine-tuning, prompt engineering)
Build and optimize data processing and document analysis pipelines
Co-design scalable and efficient AI system architecture
Integrate LLM capabilities with backend services and other system components
Experiment with AI approaches and proactively propose improvements
Collaborate closely with developers and analysts
Actively contribute to product direction, not just implementation
Technical Requirements
Minimum 5 years of commercial experience as a Python Developer
Senior-level proficiency in Python
Hands-on experience with:
LLMs / AI (e.g., OpenAI or open-source models)
prompt engineering
Retrieval-Augmented Generation (RAG)
model fine-tuning
Experience designing data processing and AI systems
Strong understanding of backend architecture
Nice to have:
FastAPI
Docker
AWS or other cloud platforms
Soft Skills (high priority!)
Strong critical thinking — ability to analyze, challenge, and improve solutions
Proactivity / push-forward mindset — driving the project forward independently
Ownership and initiative — proposing solutions, not waiting for tasks
High level of autonomy and self-organization
👉 This role is for someone who wants to co-create the product, not just execute tasks.
