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 Kuro

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 10 people based in Berlin. You will join a group of ex-technical founders and builders that are ambitious and kind.

About the role

Your responsibilities

You will own and operate on improving and adding new features to our AI automation use cases. Each construction project from our customers consists of 300 - 3000 files ranging from PDFs, over drawing, scans etc. On top of these data we are builidng high impact automation or insight use cases that help our customers save days of work (e.g. one use case cuts down the workload from 5 days to 4 hours). Unlocking new levels of ROI and impact. Your job is to prototype, optimise and productionize these use cases for our customers.

You will be working closely with Jonas (CPO)

Optimize and Productionize Solutions

• Manage experimentation pipelines and perform error analysis.

• Oversee evaluations, scoring, and golden data set creation.

Enhance ML and Data Pipelines

• Continuously improve pipelines to support new and existing use cases

Refine Evaluation Processes

• Optimize evaluation and scoring systems for robust performance monitoring.

Past and current projects you would have been involved in

• Boosted accuracy by 9% through prompt engineering with customer feedback.

• Achieved an 11% accuracy improvement using LLM for prompt rewriting (LLM-as-an-audience).

• Reduced hallucinations by implementing an LLM-as-judge approach.

• Enhanced search relevance through BM25/Hybrid Search implementation.

• Developed use cases like mapping 3D-model metadata using LLMs.

Current Tech Stack

It is still day 0 for Kuro. Therefore we are highly pragmatic with our tool choices. We believe in keeping it simple and moving quickly. You significantly help shape our tech stack decisions.

• Web-App: Typescript / Vite

• Cloud Functions: Supabase

• Database / Vector DB and File Storage: Supabase (postgress) / Weaviate / AWS S3

• Backend (Document Pipelines & applied AI): Fastify API / TS + Python for ML Services

• Hosting: Railway (Moving to AWS)

• AI: Azure / OpenAI, Gemini, Cohere

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

Your Opportunity

You are joining Kuro at the moment it matters most. The product is live, customers are paying, and the hard platform challenges are just beginning. Construction generates the most complex, unstructured data you can throw at an LLM — PDFs, drawings, 3D models, images, calculations. This is the most challenging applied AI problem you can work on, in an industry we all depend on.

This is your chance to join extremely early and help build the core infrastructure for construction automation. You'll be one of our first engineering hires — working on real customer problems from day one, making technical decisions with direct impact, and shaping both the product and how we build it. You'll own meaningful parts of Kuro end-to-end, with the autonomy to grow as a strong individual contributor or take on leadership responsibility over time.
