tl;dr

After 14 years in construction tech, Lea & Jonas are building the AI foundation for the construction industry
6 of the 20 largest construction companies in the German-speaking region already rely on Kuro every day, representing over €40bn in combined annual construction volume
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

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 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 €10 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. You will join a group of technical ex-founders and builders who are ambitious and kind.

What You'll Do

Set the technical direction

Own the architecture decisions for the platform, from document ingestion to the chat UI
Write and review RFCs. The technical roadmap for the next two to three quarters is yours.
Make the build-or-buy decisions: which models we use, and which retrieval and orchestration stack we build on.
Turn a vague customer request ("show me where the bid deviates from the BoQ") into a scoped plan with the risks named.

Raise the bar for the team

Mentor engineers: Review their designs and their code.
Define the engineering standards. Find what slows the team down, in tooling or in the CI/CD pipeline, and fix it.
Interview and hire engineers.
You have no direct reports. You change decisions in product and in other teams with a written argument.

Build and own end-to-end (AI) features

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.

Build the platform that abstracts workflow building

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

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, 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

Projects you would be involved in

Current & Past projects

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
