Senior AI Agentic Engineer

Job Summary:

The Senior AI Agentic Engineer, based in Athens, Greece, bridges both worlds — owning the product vision and roadmap for Profile One, while leading the technical architecture of our AI projects. This is a hybrid role for someone who thinks in products and builds in systems, equally comfortable defining what gets built and getting into the detail of how it works.

What will you need to do:

Agentic architecture and engineering

•      Own the architecture of the Group's agentic platform: orchestration patterns (supervisor / sub-agent), agent decomposition, tool-calling design, memory and state management, error handling and human-in-the-loop integration.

•      Lead implementation across the agent framework stack — LangGraph, LangChain or equivalent — with a strong opinion on framework choice and lifecycle.
