Fullstack Software Engineer

tl;dr After 14 years in construction tech, Lea & Jonas are building the intelligence layer for the construction industry The largest construction enterprises in Europe — with a combined project volume of over €30bn annually — rely on Kuro every day to automate workflows and make faster, better decisions Construction has the most complex, unstructured data you can throw at an LLM — PDFs, drawings, 3D models, images, calculations. At Kuro you can tackle the hardest applied AI problems everyday. About us Lea and Jonas scaled two of Europe's leading construction tech companies - Capmo and alcemy - and saw firsthand the challenges holding the industry back. Now they're tackling the root cause: the 50% of construction work still lost to manual data handling. Kuro is the the intelligent project data system for construction. We're reimagining how construction professionals get work done and make decisions by leveraging AI to augment back-office workflows and make core data accessible. After one year on the market leading construction enterprises with a combined construction volume >30 billion annually use Kuro everyday to automate workflows and make faster, better decisions . We are 16 people based in Berlin. You will join a group of ex-technical founders and builders that are ambitious and kind. Learn more: Join Kuro - Berlin The Opportunity You will build and own customer-facing features end-to-end — and alongside that, work with the team on the data platform they stand on: ingestion pipelines, the construction ontology and the project graph. Each customer project consists of 300 - 3,000 files: PDFs, construction drawings, scans, 3D models. Performant ingestion and a well-structured graph are the foundation for everything we are building from accuracy to ROI and user experience. What You'll Do Build and own end-to-end features Designing and implementing new features to solve a specific user problem such as file navigation or document versioning From concept, to db schema to UI - own the full development lifecycle of customer-facing features Manage our web application & APIs Maintain and improve our web application's security and performance; build out existing and new features Work on the construction ontology & project graph Help model and evolve canonical entities of our customers Contribute to entity resolution across sources: recognizing the same requirement, position or price across BoQs, contracts, drawings and bids Build features so answers are evidence-linked and auditable, and decisions flow back into the graph Contribute to scalable data pipelines & integrations Extend our multi-modal ingestion of unstructured documents: PDFs, scans, drawings, 3D models. Orchestrated and cost-efficient at scale Build read/write integrations with customer systems (document management, ERP/AVA), so workflows complete work end-to-end Help build the abstraction layers that turn use cases into a platform Contribute to the workflow harness, decis
