Software Engineer - AI

• After 14 years in construction tech, Lea & Jonas are building the AI foundation for the construction industry

• Leading European construction enterprises with >€40bn in combined annual construction volume already rely on Kuro every day

• Construction 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 day

• Curious about the bigger engineering challenge? Explore the vision and open problems at kuro.build .

• Design and implement new features to solve a specific user problem, such as document versioning or our agentic Chat.

• From concept to DB schema, to optimizing LLMs, to UI. Own the full development lifecycle of customer-facing features.

• Manage evaluations and scoring, and perform error analysis on new and shipped AI features.

• Contribute to the workflow harness, decision-trace standard, and eval tooling so a new use case ships in ~1 month

• Build reusable human review & approval surfaces where trust in AI output is earned

• 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

• Extend our multi-modal ingestion of unstructured documents - PDFs, scans, drawings, and 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

• Project & document versioning guaranteeing data lineage in construction projects

• German tokenizer for construction-specific search

• Document pipeline ingesting 10,000s of PDFs per day

• Native BIM/DWG file support: ingesting and processing 3D models

• Design the ontology v1 + graph schema: core construction entities, evidence links, and per-customer extension model

• Build out our workflow harness to run agentic workflows for customers
