Software Engineer - AI

tl;drAfter 14 years in construction tech, Lea & Jonas are building the AI foundation for the construction industryLeading European construction enterprises with >€40bn in combined annual construction volume already rely on Kuro every dayConstruction has some of the most complex, unstructured data you can throw at an LLM. At Kuro, you can tackle some of the hardest problems in applied AI every dayCurious about the bigger engineering challenge? Explore the vision and open problems at kuro.build. About usLea 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 building the AI foundation 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. We are not pursuing marginal improvements, but a step change for construction. After one year on the market, leading construction enterprises with a combined annual construction volume of >€40 billion use Kuro every day to automate workflows and make faster, better decisions. Backed by an €8 million seed round, we already process more than 1 million pages every month and expect that volume to grow 10x over the next six months. We are 15 people based in Berlin.
