We are looking for a developer with entrepreneurial ambition and the ability to grow into a founding role, to turn the existing research prototype into a working MVP fast enough to support the next grant application round.\nMain duties and responsibilities\nRebuild the RVI scoring engine as clean, standalone Python code, implementing the validated indicator formulas correctly\nDesign and build the database layer (schema and storage) and connect it directly to the RVI engine\nMigrate the graph representation from Neo4j to a Python-native structure\nImplement data-ingestion and similarity-matching logic that completes missing component information (GNN)\nBuild the web interface: data upload in, ranked results out\nWork independently from rough goals to working software, using modern tooling (including AI coding assistants) to move fast\nKeep the codebase clean and documented so it can be extended by others.\nProfile\nThe role combines graph data, ML, and practical web development. Some technologies may be learned during the project, but solid Python skills and hands-on experience with graphs and GNNs are essential.\n Full-stack: able to own backend, data layer and frontend as one coherent system (upload data, run scoring, show ranked results).\nDegree in computer science, software engineering, data science, machine learning, or an equivalent field; \nStrong Python skills; experience with APIs, databases, data pipelines, testing and deployment.\nHas personally built and shipped at least one complete software product or system beyond coursework.\nAble to translate research or mathematical logic into reliable software.\nUses AI coding tools effectively, but independently reviews, tests and takes full responsibility for the resulting code.\nGraph data, ML/GNN, and LLM experience is a strong advantage.\n Ability to parse and work with structured building-data formats (BIM/IFC), or equivalent experience ingesting structured technical data from PDF/Excel sources \nCivil engineering or broader construction-industry background is an advantage, not required.\nValid Swiss work permit is mandatory. Applications without one will not receive a response.\nPriority will be given to candidates already based in Canton Vaud or the Lausanne region, available to start immediately.\nWe offer\nThe chance to build the technical core of an EPFL spin-out in formation, in circular construction and AI\nDirect collaboration with the founder and real ownership of what you build\nA flexible, hands-on role with genuine impact\nLocation: EPFL, Lausanne.\nEmployment rate: 60-80%.\nFixed-term contract, approximately 2-3 months.\nStart date: ASAP.
