BAWAG Group is the listed holding company of BAWAG P.S.K., which is one of the largest banks in Austria with 4 million customers. As a dynamic employer, we promote talent and drive technological innovations quickly. Flat hierarchies, a flexible working environment and equal opportunities for our employees are particularly important to us.Role Overview:We are evolving from standard analytics to advanced AI engineering. We are looking for a builder who can navigate the full stack—from engineering backend APIs to designing the front-end interfaces that allow users to interact with complex AI models. You will play a key role in operationalizing ourGraphRAG(Retrieval-Augmented Generation) systems, moving from experimental scripts to robust, interactive applications.Our Technology StackAI & Backend Engineering:Python (FastAPI): For building high-performance, asynchronous REST APIs to serve our models and graph data.GraphRAG & OpenAI: Leveraging generic Graph approaches and Azure OpenAI models for advanced relationship mapping and knowledge retrieval.Graph Databases: (e.g., Neo4j, NetworkX, or similar) for storing and traversing complex knowledge structures.Application Interface:Streamlit: For rapid prototyping and internal testing of algorithms.React: (Key Focus) For building the production interface that allows users to visualize, explore, and query our Knowledge Graphs intuitively.Data Platform:Snowflake: For scalable analytics and structured data storage.Orchestration & DevOps:Airflow: For orchestrating complex data and AI workflows.GitHub & Jenkins: For CI/CD, version control, and automated deployment.What You'll DoEngineer AI Backends: Design and deploy scalable FastAPI endpoints that handle complex queries and serve data from our Knowledge Graphs to the frontend.Build Interactive Graph Interfaces: Take proven concepts from Streamlit and re-engineer them into responsive React applications. Your goal is to build UIs that make navigating complex graph data simple and actionable for business users.Optimize GraphRAG Pipelines: Refine our RAG strategies to ensure our AI retrieves the most relevant contexts from our graph structures.Productionize Prototypes: Bridge the gap between data science and software engineering by rewriting experimental Python code into production-grade, maintainable software.CI/CD & Deployment: Use Jenkins and GitHub to maintain a robust deployment pipeline for both the backend APIs and the frontend applications.Your ProfileSomeone with a strong data/backend foundation (Python, API design) who is not afraid of the frontend.Experience or strong interest in React—specifically in how to visualize data (charts, graphs, networks).A "Product Engineering" mindset: You care about how the AI output is actually consumed by the user.You are currently enrolled in a university degree program, ideally with a technical focusOur OfferModern Tech Stack: Work with a clean, efficient stack (FastAPI, React, Snowflake, Airflow) where you spend more time building and less time maintaining legacy systems.Complex Engineering Challenges: Move beyond standard analytics to solve hard problems in GraphRAG and knowledge retrieval, building systems that truly understand data relationships.Hybrid Career Growth: This role sits at the intersection of Data Science and Full-Stack Engineering—a perfect opportunity to master the end-to-end process of building AI products.Ownership & Autonomy: We trust our team to make technical decisions. You will have the freedom to architect solutions and choose the best tools for the job.Tangible Impact: You aren't just generating reports. You are building the interactive applications and tools that our business teams use every day to make decisions.You will spend your office days in our modern, easily accessible office at Vienna Central Station.You can expect an exciting and instructive internship for 5 to 6 months.For the internship, a monthly gross salary of € 2,500.00 applies on the basis of full-time employment.Your contact person: Sophie Piehslinger *We value people.Would you like to work in a team where good cooperation and diversity are actively practiced? Then you've come to the right place. Equal opportunity is important to us - regardless of age, gender, sexual orientation, physical impairment, religion or origin.BAWAG| Xing | LinkedIn | Facebook | whatchado | Instagram
