Freelance (B2B contract)
Location: Spain
Work regime: Fully remote
Keywords: ML, LLMs, AI, Python, AWS

Position Overview :

We’re looking for a Data Scientist with a minimum of 2+ years of experience who is passionate about Natural Language Processing (NLP), Generative AI, and traditional machine learning. The candidate should know how to ship high-impact, production-grade models. This is a hands-on role involving the entire ML lifecycle: from prototyping to deployment, with a focus on production-readiness, APIs, and scalable architecture. You’ll collaborate with AI engineers, product managers, and domain experts to develop intelligent systems that generate next-generation insights for the pharma industry.

What you'll do :

1. Design and develop NLP and generative AI solutions using LLM frameworks like LangChain, LlamaIndex, CrewAI, or direct APIs such as OpenAI, Anthropic, HuggingFace.
2. Build and fine-tune traditional ML models (classification, regression, clustering) to support data-driven applications.
3. Create robust and scalable AI pipelines and APIs using Python and FastAPI.
4. Deploy models to production using AWS services such as ECS, Lambda, S3, with attention to CI/CD, observability, and cost-effectiveness.
5. Architect scalable, maintainable, and secure ML systems.
6. Apply critical thinking to analyze complex problems, identify edge cases, and propose pragmatic, data-driven solutions.
7. Explore new ML techniques, tools, or approaches to push boundaries.
8. Work closely with cross-functional teams to translate business problems into AI solutions.
9. Contribute to a culture of technical excellence and innovation in a fast-moving AI/ML team.

What you bring :

• Minimum 2 years of industry experience in data science or machine learning.
• Strong background in NLP, LLMs, and generative AI—familiar with both theory and tooling.
• Experience with modern LLM stacks like LangChain, LlamaIndex, CrewAI, or similar.
• Proficiency in traditional ML methods using libraries like scikit-learn, XGBoost, etc.
• Expert-level Python programming skills, beyond notebooks, with clean, maintainable, testable code.
• Experience exposing models as production-ready APIs using FastAPI or similar frameworks.
• Strong understanding of AWS services—especially ECS, Lambda, S3.
• Experience with MLOps and DevOps practices (Docker, Terraform, Azure DevOps, Github Actions) is a plus.
• Proven system architecture, problem-solving, and project leadership skills.
• Ability to work independently in a fast-paced, remote environment.
