About the Role

We are looking for a senior Gen AI & Data Science Engineer who can design, build, and productionize AI solutions on Microsoft Azure — especially using Azure OpenAI and the broader Azure AI stack. This is a hands-on, solution-building role for someone who has already delivered real-world GenAI / RAG / analytics projects.


Key Responsibilities

  • Architect and implement GenAI applications using Azure OpenAI (GPT, embeddings, assistants) and Azure AI Foundry.
  • Design and optimize RAG (Retrieval-Augmented Generation) pipelines: document ingestion, text/vector embeddings, chunking strategies, metadata, hybrid search, evaluation.
  • Work with vector databases (e.g. Azure AI Search, Redis, PostgreSQL with pgvector, Milvus, Pinecone) and implement vectorization of text and semi-structured data.
  • Build and orchestrate agentic workflows using frameworks like LangChain, Crew.AI, A2A or equivalent to support multi-step, tool-using AI agents.
  • Develop and deploy predictive analytics and ML models (classification, regression, time series, anomaly detection) aligned to FS use cases (KYC/AML, collections, underwriting, RoI modeling, pricing, customer insight).
  • Package solutions as APIs / microservices for consumption by business apps, portals, or channels.
  • Define MLOps / AIOps practices on Azure (CI/CD, model registry, monitoring, drift, evaluation).
  • Work closely with business stakeholders to translate requirements into data/AI products.
  • Ensure security, governance, and data privacy compliance for financial services workloads.


Skills & Qualifications

  • 7-10 years of experience in Data Science / ML / AI engineering roles.
  • European nationality (EU passport) — for mobility / customer/regulatory reasons.
  • Strong, recent hands-on experience with Azure OpenAI and Azure AI services (AI Foundry / AI Search / Cognitive Services).
  • Proven experience in building RAG systems end-to-end (data prep → embedding → retrieval → prompt orchestration → evaluation).
  • Solid understanding of embeddings and vector similarity search (cosine / dot product / hybrid).
  • Practical experience with LangChain or similar chain-of-thought / tool-calling frameworks.
  • Hands-on with agentic frameworks (Crew.AI, A2A, AutoGen, etc.) for multi-agent task execution.
  • Excellent Python skills (pandas, PyTorch/TF/sklearn, FastAPI).
  • Experience in financial services data models and processes.
  • Strong architecture mindset: can choose the right Azure service for the problem.
  • Very good English communication; able to present to non-technical stakeholders.


Why join us


  • Work with a pragmatic, execution-focused team that values quality over shortcuts.
  • Autonomy to choose the right tools/architectures and set engineering standards.
  • Build category-defining AI systems for high-impact financial use cases
