We’re looking for:

ML engineer who can build everything from scratch — from the first lines of code to a full production system. We don’t have a ready-made ML infrastructure yet, but we do have data that’s waiting for you. You'll need to gather it, choose the right models, build pipelines, deploy them, and launch into production. No ready-made templates — just full freedom and real product impact.

Requirements:

• Strong proficiency in Python

• Solid experience with frameworks like PyTorch or TensorFlow

• Experience working with NLP libraries (Hugging Face, spaCy, etc.)

• Experience building and automating ML pipelines (training, validation, deployment)

• Experience developing recommendation systems and personalization solutions

• Confident in using image processing tools such as OpenCV, torchvision, and PIL

• Knowledge of computer vision libraries like Detectron2 (or equivalents)

• Strong data analysis skills using NumPy and pandas

What you'll do:

• Launch multimodal models (image + text)

• Design and implement the full ML pipeline architecture — from data collection to production

• Improve recommendation accuracy and personalization based on user behavior analysis

• Set up metrics, monitoring, and A/B testing frameworks

• Collaborate with developers to integrate models into production systems and optimize for scalability and efficiency

What we offer:

• Salary

• Benefits package

• On-site (if you’re in Warsaw, Poland) / Remote

• Friday parties at the office in the center of Warsaw

• Chill & Hiking in the Polish Tatras 2 times a year:)
