About the position
Quantum is expanding its team in Central Europe and is looking for talented Data Science Engineers to join us. Our projects span multiple domains, including data analysis, fintech, computer vision, image processing, edge-device solutions, Large Language Models (LLMs), and classical Machine Learning applications. We build custom Data Science solutions for clients across various industries, combining strong engineering practices with a research-driven mindset.
Joining Quantum means becoming part of a team that values solid technical fundamentals, continuous learning, and practical problem-solving. You’ll collaborate on impactful products, work with cutting-edge technologies, and contribute to projects that turn complex ideas into real-world solutions.
Must have skills:
- 2+ years of commercial DS/ML experience
- Solid foundation in linear algebra, statistics, and probability
- Strong Python, including NumPy, Pandas, and scikit-learn
- Hands-on experience with PyTorch (or TensorFlow)
- Deep experience in at least one of: Computer Vision (modern DL: detection, segmentation, classification - ViT, YOLO, SAM); LLMs / NLP (fine-tuning, RAG, prompt engineering, embeddings, evaluation); Classical ML at scale (tabular, time series, recommender systems)
- Working knowledge of Transformers and attention; familiarity with CNNs
- Experience deploying models to production (Docker, REST/gRPC serving, basic monitoring)
- Experience with at least one cloud platform (AWS, GCP, or Azure)
- Clean code and Git workflow
- Experience with SQL
- Upper-Intermediate English (B2+) - you'll communicate directly with clients
Nice to have skills:
- Cross-domain exposure: if your main strength is CV, some LLM exposure is a plus (and vice versa)
- Edge deployment: TensorRT, OpenVINO, ONNX, quantisation, model distillation, mobile/embedded inference
- LLM tooling: LangChain/LlamaIndex, vector databases (pgvector, Pinecone, Weaviate, Qdrant), LoRA/QLoRA fine-tuning, agentic frameworks
- MLOps & model monitoring: MLflow, DVC, Weights & Biases, CI/CD for ML
- Classical CV with OpenCV (still relevant for hybrid pipelines and edge work)
- Ability to read recent papers and implement methods in new domains
- Experience working with external clients
- Participation in Kaggle competitions
Your tasks will include:
- Own full-cycle DS projects: scoping with the client, data prep, modelling, evaluation, deployment
- Build solutions across CV, LLM/NLP, and classical ML depending on the project pipeline
- Deploy models to production - cloud, edge, or hybrid, depending on client needs
- Read recent research and adapt methods to client problems
- Communicate technical decisions and trade-offs directly to clients
We offer:
- Delivering high-end software projects that address real-world problems
- Surrounding experts who are ready to move forward professionally
- Professional growth plan and team leader support
- Taking ownership of R&D and socially significant projects
- Participation in worldwide tech conferences and competitions
- Taking part in regular educational activities
- Being a part of a multicultural company with a fun and lighthearted atmosphere
- Working from anywhere with flexible working hours
- Paid vacation and sick leave days
