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.
You should know how to ship high-impact, production-grade models.
This is a hands-on role working across the full 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 power next-generation insights for the pharma industry.
What you'll do: Design and develop NLP and generative AI solutions using LLM frameworks like LangChain, LlamaIndex, CrewAI, or direct providers such as OpenAI, Anthropic, HuggingFace. Build and fine-tune traditional ML models (e.g., classification, regression, clustering) to support data-driven applications. Create robust and scalable AI pipelines and APIs using Python and FastAPI. Deploy models to production using AWS services such as ECS, Lambda, and S3, with attention to CI/CD, observability, and cost-effectiveness. Architect scalable, maintainable, and secure ML systems, applying critical thinking to analyze complex problems, identify edge cases, and propose pragmatic, data-driven solutions. Explore new ML techniques, tools, or approaches that push the boundaries of what we can do. Work closely with cross-functional teams to turn ambiguous business problems into well-scoped, technically sound AI solutions. 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—comfortable with both theory and tooling. Familiarity with modern LLM stacks such as LangChain, LlamaIndex, CrewAI, or similar. Skilled in traditional ML methods using libraries like scikit-learn, XGBoost, etc. Expert-level Python programming skills, beyond notebooks—writing clean, maintainable, testable code. Experience exposing models as production-ready APIs using FastAPI or similar frameworks. Strong understanding of AWS services—especially ECS, Lambda, and S3. Experience with MLOps and DevOps best practices is a plus (e.g., Docker, Terraform, Azure DevOps, Github Actions). Proven ability in system architecture, problem-solving, and independently leading projects from concept to deployment. Comfortable working independently in a fast-paced, collaborative, remote-first environment. A little about us: Innova Solutions is a diverse and award-winning global technology services partner.
