Data scientist / ML (Cheminformatics)

Компания "Балхаш Системс"

We have 30 years of expertise in designing and building custom software systems. We provide software development services focusing on complex high-load applications, AI and BI solutions, and mobile apps.

Project focused on virtual developability/progressability analysis for small molecules.
The goal is to improve hit triaging and decision-making in early-stage medicinal chemistry by leveraging machine learning, active learning, and statistical approaches. The team works closely with scientists to identify the most informative compounds for experimental testing, improve ADME prediction models, and rank chemical series based on their potential.

The scope of work includes improvement of existing ML models, design of training datasets, active learning workflows, uncertainty estimation, analysis of chemical data, and automation of ML pipelines. A single analysis may include up to 100K compounds.
Analysis functionality will be integrated with existing molecular design and data-driven decision-making platforms and may require development of simple Streamlit/Dash applications.

Required skills

• Strong Python (4+ years of experience).
• Experience with AI/ML model development and analysis (RF, GPs, LGBM, GNNs, etc.).
• Strong understanding of statistics and model evaluation.
• Experience working with:
  • small datasets;
  • imbalanced datasets;
  • uncertainty quantification;
  • active learning approaches.
