About Your Future Team 
You will join the Generative AI & Data Engineering team – a pioneering unit focused on delivering intelligent solutions that power AI-driven products and decision-making. We work at the intersection of structured enterprise data and unstructured content (text, images, documents), enabling next-gen applications in NLP, LLMs, and intelligent search. 

In this role, a typical day will include:

• Build and optimize robust data pipelines to ingest, process, and serve structured (SQL, tabular) and unstructured (PDFs, text, images) data to downstream GenAI systems. 

• Design scalable and modular ETL/ELT workflows using Azure Data Services (Azure Cognitive Search, Azure Document Intelligence, etc). 

• Develop reusable and modular Python components for preprocessing unstructured data for GenAI models. 

• Design and deploy data workflows using Docker containers for environment consistency and scalability. 

• Orchestrate data pipelines and jobs using Apache Airflow, ensuring reliable scheduling and monitoring. 

• Collaborate closely with LLM engineers, data scientists, and product teams to ensure data readiness for RAG, embeddings, and vector databases. 

• Handle large-scale data transformations, metadata tagging, and schema evolution across data formats (JSON, CSV, Parquet, images). 

• Integrate Azure OpenAI and other LLM APIs into the data workflow when required. 

• Contribute to the data layer that supports chatbots, document summarization, and intelligent assistants. 

• Work in Agile teams with global collaboration across data, AI, and product domains. 

WHAT YOU’LL BRING TO ALCON:  

• 3+ years of experience in Data Engineering, especially in cloud-first environments. 

• Strong hands-on skills in Python (data wrangling, file parsing, API integration) and SQL (complex queries, performance tuning). 

• Experience with unstructured data processing – PDFs, images, HTML, JSON, etc. 

• Solid understanding of Azure Data Stack: Data Lake, Azure Search, Azure Blob. 

• Comfortable working with large language models, vector stores. 

• Practical experience in preparing data for GenAI pipelines – at least 2 large-scale projects (e.g., chunking, vector embeddings). 

• Strong working knowledge of Docker and containerization best practices. 

• Hands-on experience in designing and maintaining DAGs in Apache Airflow. 

• Familiarity with data formats and standards relevant to AI (e.g., tokenization, embeddings, ML metadata). 

• Bonus: Experience with AWS or Hybrid Cloud Environments 

• Familiarity with CI/CD pipelines, version control (Git), and DevOps practices. 

• Proactive, curious, and adaptable with strong communication skills. 

• Fluent in English – written and spoken. 

HOW YOU CAN THRIVE AT ALCON:

• Competitive compensation package and hybrid working model (3+2). 

• Performance-linked annual bonus. 

• Direct exposure to Generative and Agentic AI product development. 

• Training and certification support in Azure, OpenAI, Databricks, and LLM platforms. 

• Work on cutting-edge use cases like intelligent search, automated document insights, and AI copilots. 

• A collaborative culture that values creativity, data craftsmanship, and innovation. 
• Flexible hours and hybrid model of work (3/2, weekly),
• Brand new office in Marynarska 15, Warsaw, with a lot of facilities inside
