Postdoc in Process Chemistry and Digital Synthesis

We are currently looking for a 12-months (with the possibility to extend the contract to 24-months) Postdoctoral Fellowship contract in our Process Technology department in Münchwilen. The role sits at the interface of chemistry and digital innovation focused on designing and evaluating human-in-the-loop methodologies that combine generative chemistry AI with expert synthetic knowledge to accelerate synthesis route scouting. You will collaborate across teams benchmarking digital synthesis tools and identifying the most promising directions for adoption across Syngentas synthesis programs. You will be given the opportunity to develop new skills while working at the cutting edge of chemistry data science and AI.

Your responsibilities: 

• Design and execute structured evaluations of generative chemistry AI tools combined with expert chemical judgment 

• Develop and document reusable benchmarks based on internal route catalogs and external literature datasets 

• Investigate multiple methodological approaches for AI-assisted synthesis route improvement 

• Integrate digital synthesis tools into live route scouting activities 

• Conduct literature reviews to identify and prioritize promising directions in generative chemistry 

• Capture and communicate findings through internal reports presentations and potential scientific publications 

Qualifications :

• A PhD in digital chemistry organic chemistry cheminformatics or a closely related field 

• Sound knowledge of synthetic organic chemistry and retrosynthetic analysis 

• Working knowledge of cheminformatics concepts: molecular representation (SMILES InChI) reaction databases retrosynthesis logic 

• Familiarity with generative chemistry or AI-assisted synthesis planning tools (e.g. AiZynthFinder ASKCOS IBM RXN or similar) is a plus 

• Python proficiency covering cheminformatics (RDKit) data analysis (pandas) version control (Git) and unit testing 

• Ability to critically evaluate and benchmark AI-generated synthesis routes against expert knowledge 

• Comfortable working across chemical development and digital/data science teams 

• Fluent English with strong written and verbal communication skills
