Software Engineer - AI

tl;dr

• 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 .

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

What You'll Do

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

• Obsv., Eval. & Tracking: Langfuse, Datadog

Your profile

This is the perfect role for an experienced engineer who wants to join an early stage company that builds a high impact applied AI product

• Bring 3+ years of experience as a (full-stack) software engineer in a fast-paced environment

• Have proven experience delivering production-grade applied AI features to customers

• Take full ownership of solving customer problems by designing and implementing AI features

• Thrive in a small, accountable team with a high degree of ownership and a drive to make an impact

• Communicate fluently in both spoken and written English

• Enjoy working onsite with the team at our office in Factory Berlin Mitte every day

Bonus Points
