About our client

Our client is a global technology company that has been at the forefront of data innovation for over four decades. With offices across North America, Europe, and APAC, they support large enterprise clients in making better decisions through advanced analytics, data science, and cloud-based platforms.

Their European tech hub combines enterprise-level scale with innovation-driven AI initiatives. The team works on real-world use cases, particularly in finance and regulated industries, where generative AI is applied to large operational and log-based datasets.

The company fosters an open, knowledge-sharing culture where experimentation is encouraged, and AI solutions are built with long-term scalability and measurable business impact in mind.

Job description

We’re looking for a Senior Generative AI Data Scientist who will design and deliver AI solutions connected to large enterprise datasets.

You will operate within a focused, high-impact team where generative AI is applied to real-world financial use cases. A key part of the role is direct collaboration with French-speaking stakeholders — understanding business needs, shaping AI solutions, and ensuring production readiness.

Your responsibilities:

• Design and deliver generative AI solutions (LLMs, RAG, transformer-based systems)
• Work directly with Teradata databases and integrate enterprise data sources into AI workflows
• Build, test, and deploy machine learning models using Python
• Develop generative AI use cases based on structured and unstructured datasets
• Translate business requirements into scalable AI architecture
• Present findings and technical solutions to technical and business audiences
• Collaborate with engineers and data specialists during scaling and implementation phases
• Take ownership of AI solutions from proof-of-concept to production

This is a senior, hands-on data science role with direct business exposure — not a pure research position.

Requirements

• Proven senior-level experience as a Data Scientist
• Hands-on experience with generative AI (LLMs, OpenAI, Hugging Face, LangChain, transformers, etc.)
• Strong SQL and experience working with large enterprise datasets
• Advanced Python skills (Pandas, NumPy, Scikit-learn, etc.)
• Experience deploying AI models into production environments
• Strong communication and stakeholder interaction skills
• Fluent English

Nice to have:

• Experience with MLOps, CI/CD for ML
• Experience with cloud platforms (AWS, Azure, GCP)
• Background in financial services or regulated enterprise environments

Offer & Terms

• Strategic generative AI initiative within a major European financial organization
• Freelance / IČO cooperation
• Long-term collaboration until end of 2026 (extension expected)
• Remote-first setup
• Occasional travel to France
• Senior-level ownership and technical autonomy

More information

This opportunity is open to candidates based in the Czech Republic with valid EU work authorization and the ability to cooperate on a B2B/freelance basis.

Occasional business travel to France can be expected.

The selection process is led by a senior IT recruiter with strong technical background, ensuring a relevant and professional discussion.

If this sounds like you, we’d love to hear from you.
