Bucharest, Bucureşti, Romania Patrianna Full time €90,000 - €120,000 per year

Patrianna
is a rapidly expanding product development company headquartered in Gibraltar, with a dynamic team spanning the globe. We are on the lookout for exceptional talent—driven, ambitious individuals who are ready to elevate business functions with expertise, adaptability, and a passion for continuous growth.

We're looking for an AI Engineer to lead the development of an intelligent, self-evolving data ecosystem powered by large language models (LLMs). You'll be at the forefront of innovation, blending data engineering, real-time intelligence, and AI productization to deliver cutting-edge solutions across the business.

Key Responsibilities
LLM-Oriented AI & Automation Systems

  • Build, fine-tune, and integrate LLM pipelines using platforms such as Vertex AI, OpenAI, Google Studio for data transformation, summarization, and retrieval-based tasks.
  • Develop prompt-driven automation systems for workflows including metadata extraction, tagging, reporting, and anomaly detection.
  • Design and deploy RAG (Retrieval-Augmented Generation) and embedding-based search solutions integrated with enterprise knowledge bases.

Agent Orchestration & Autonomy

  • Build intelligent agents using CrewAI, LangChain or similar frameworks to support use cases like automated report generation, root cause analysis, and interactive user agents.
  • Implement feedback and memory mechanisms to support context-aware, evolving agents.

AI-Native API & Platform Integrations

  • Develop, manage, and scale API integrations that connect AI workflows with data warehouses, business tools, and external data sources.
  • Create intelligent endpoints for model inference, decision logging, and webhook/postback triggers to support real-time interactions and data enrichment.

Data Modeling for AI Workflows

  • Architect and maintain data models optimized for AI usage—structured for quick access by LLMs, retrieval engines, and embedded reasoning tools.
  • Integrate semantic layers and metadata mapping to facilitate natural language querying and low-code data exploration.

Documentation, Scaling & Knowledge Ops

  • Document all AI workflows—from prompt structures and agent behaviors to API interfaces and data flows—for reproducibility and team-wide collaboration.
  • Build internal knowledge bases, vector stores, and wiki systems fueled by LLM summarization and indexing.
  • Advocate for internal AI adoption through tooling, workshops, and scalable use case frameworks.Preferred Qualifications

Must-Have

  • Bachelor's degree in Computer Science, Data Science, AI/ML, or related field.
  • Strong experience with GCP ( Vertex AI, Google Studio and other GCP tools).
  • Demonstrated success integrating LLM APIs (OpenAI, Vertex AI, Perplexity, Gemini) into production systems.
  • Expertise with LangChain, CrewAI, OpenAI platform or similar frameworks.
  • Expertise in building and deploying JS/n8n/Python-based AI workflows, agents, and APIs.
  • Solid SQL knowledge for structured data operations and AI-data interplay.

Nice to Have

  • Google Cloud certifications in Data or Machine Learning.
  • Experience with vector databases, embedding generation, and RAG infrastructure.
  • Exposure to autonomous agent memory systems, reward tuning, or action planning loops.
  • Familiarity with Data Engineering process and tools.
