- Machine Learning Model Validation Consultant
About the Role
We are looking for a consultant who will focus on validating and testing AI/ML-enabled systems that are used in highly regulated industries (such as pharmaceuticals and life sciences). These systems must follow strict compliance guidelines like GxP/GMP standards.
The role ensures that whenever AI, Machine Learning, or automation features are added to existing systems-or when new platforms are integrated-these solutions are trustworthy, reliable, and compliant with regulations.
Key Responsibilities
AI/ML System Validation

• Test and validate AI/ML models to ensure accuracy, fairness, and compliance.
• Apply methods like confusion matrices, precision, recall, F1 scores, and other metrics to check model performance.
• Validate both traditional ML models and LLM (Large Language Models) or RAG (Retrieval-Augmented Generation) systems.

Compliance & Regulatory Testing

• Design and execute validation strategies that meet GxP/GMP regulatory requirements.
• Ensure that AI/ML-enabled systems in regulated environments are transparent, auditable, and safe.

Integration Testing

• Test new components and features being added to existing platforms.
• Ensure integrations (AI tools, ML models, or rule-based systems) work smoothly and produce correct outputs.

Data Validation & Engineering Support

• Validate the quality, consistency, and reliability of data pipelines and data inputs used by AI/ML models.
• Collaborate with data engineering teams to ensure clean and compliant data flows.

End-to-End Output Validation

• Confirm that the final system outputs are accurate, explainable, and compliant with business/regulatory requirements.
• Document results in a clear and structured way for auditors and stakeholders.

Required Skills

• Understanding of Machine Learning concepts (classification, regression, confusion matrix, etc.).
• Knowledge of LLMs, RAG, and AI validation techniques.
• Familiarity with GxP/GMP compliance standards or regulated IT environments.
• Strong skills in data engineering concepts (data pipelines, data quality checks).
• Ability to design test strategies and document validation evidence.

Nice to Have

• Experience with cloud-based ML/AI platforms.
• Familiarity with rule-based systems and their validation.
• Strong analytical and problem-solving skills.
