• Participate in system maintenance, SDLC activities, and end-user acceptance testing for reference data systems

• Understand canonical data models and metadata definitions

• Document changes & decision rationale for data contracts and SOPs for master/reference data

• Evaluate ML/AI or NLP approaches to assist curation (e.g., entity resolution, name generation, property prediction)

• Support or lead projects and pilots to improve efficiency, data quality, and usability; identify and implement process improvements

• Serve as subject matter expert and point of contact for chemical nomenclature and reference data issues; build and maintain strong relationships with end users and stakeholders across functions

• Participate in governance forums; help establish stewardship models, KPIs (completeness, accuracy, timeliness), escalation paths, and training for data producers/consumers

• Ensure practices reflect relevant regulatory and industry standards (GxP, 21 CFR part 11, ICH, IDMP, WHO Drug Dictionary) and maintain up-to-date knowledge of nomenclature and data standards

• Preserve confidentiality and adhere to company policies governing information disclosure

Required:

• Completed at least one year of organic chemistry

• Experience or familiarity with deriving chemical nomenclature (IUPAC or CAS style)

• Experience with structure drawing software (ChemDraw, ACD, Accerlys, etc.)

• Domain expertise: Strong knowledge of chemical structures, stereochemistry, physicochemical properties, biological sequence representations and concepts , and the drug development process

• Familiarity with chemical identifiers and formats (SMILES, InChI, CAS, MOL/SDF), spectral data concepts, chemical ontologies/taxonomies, and common cheminformatics tools or libraries

• Experience establishing stewardship frameworks, SOPs, ownership models, and KPIs to maintain high quality, traceable, and compliant data

• Demonstrated history of adopting new technologies (AI, ML-assisted curation, knowledge graphs) and willingness to learn & prototype new approaches

• Very organized and able to work with high attention to detail

• Excellent written and verbal communication skills with the ability to convey technical and business information
