Byleveragingour proprietary technology,we'rebuilding an ecosystem that is leading the industry into the 21st century.

Weare a growing team looking for aMLEngineerII in theData/ML department to help us on our journey to revolutionize road freightlogistics.The roleis locatedinourBerlin,Barcelonaor Amsterdamoffices.

WHAT YOU WILL DO …

We are seeking aMachine Learning EngineerII to join ourML team. You will work on a diverse portfolio of high-impact projects, ranging fromoptimizingour established Load-to-Carrier Recommendation engine to building greenfield GenAI solutions that automate complex Operator workflows.

You will act as an end-to-endML Engineer, taking ownership from "Light MVP" prototyping to production deployment. You will tackle challenges involving both structured data (ranking/matching) and unstructured data (text/NLP).

In this role, you will …

• Develop and deploy NLP & LLM solutions: Build production-grade systems for email classification, entity extraction, and automated bidding strategies using modern transformer-based architectures and LLM APIs.
• Maintain and refine Recommendation Systems: Optimizeexisting recommender pipelinesto ensure carriers are matched with the best loads.
• Engineer scalable ML pipelines: Design robust training and inference pipelines, ensuring your models are reliable, observable, and meet strict SLAs.
• Handle unstructured data at scale: Work with Data Engineering to turn messylogisticsdata (emails, PDFs, chat logs) into structured features.
• Drive the product strategy: Work closely with Product Managers and Operators to drive the adoption of ML-poweredproductsand revolutionize the logistic industry.
• Drive experimentation: Implement A/B tests and offline evaluation frameworks to measure the real-world business impact of your models, favoring pragmatic solutions over theoretical complexity.

WHAT WE ARE LOOKING FOR …

• Experience: 5+ years of experience as a Machine Learning Engineer or Data Scientist with a strong software engineeringcomponent.
• Applied ML Expertise: Solid grasp ofNLP (Transformers, LLMs,HuggingFace) andRecommender Systems (collaborative filtering, learning-to-rank, two-towersarchitecture). You know when to use a simple regression and when to deploy a complex deep learning model.
