Senior Scientist, Cheminformatics

Position Overview:

Our Company is currently seeking an exceptional, highly motivatedSenior Scientist, Cheminformaticsto join the Modeling & Informatics group within Discovery Chemistry. The successful candidate will join multidisciplinary discovery teams to drive the development and application of advanced cheminformatics workflows, machine learning models, and data-driven methods. This role focuses on accelerating drug discovery pipelines across both small molecules and emerging modalities—such as cyclic peptides, macrocycles, and DNA-Encoded Library platforms—in close partnership with computational and medicinal chemists.

Key Responsibilities:

·Computational Chemistry Partnership:Partner closely with computational and medicinal chemists on Discovery Chemistry project teams to address challenging structure-activity relationships and multi-parameter optimization

·Emerging Modalities &DNA-Encoded LibraryInformatics:Develop and deploy specialized informatics workflows for non-traditional modalities (cyclic peptides, macrocycles) and DNA-Encoded Library platforms, including combinatorial enumeration, selection data triage, and hit prioritization.

·Workflow & Algorithm Development:Design, validate, and implement scalable cheminformatics and machine learning pipelines for predictive property modeling, virtual screening, and chemical library triage.

·Data Infrastructure & Tooling:Establish robust, automated computational tools and data pipelines that bridge internal chemical data platforms and modern modeling frameworks.

·Scientific Presence & Mentorship:Maintain an active external scientific presence through publications, conference presentations, and community engagement, while mentoring junior staff, interns, and co-ops.

Position Qualifications:

Required Education:

·     Ph.D. (or close to completion) in Cheminformatics, Computational Chemistry, Chemistry, Computer Science, Bioinformatics, or a related quantitative discipline;OR

·         M.S. degree with 4+ years of relevant industry/research experience.

Required Experience & Skills:

·         Demonstrated expertise in cheminformatics fundamentals (molecular representations, fingerprints, similarity search, tautomer enumeration, and conformer generation).

·         Strong programming proficiency in Python and scientific computing libraries (NumPy, SciPy, Pandas, scikit-learn).

·         Extensive hands-on experience with modern cheminformatics toolkits (e.g., RDKit, OpenEye Toolkits, or CDK).

·         Experience developing and validating machine learning or statistical QSAR models applied to chemical or biological data.

·         Demonstrated track record of effective collaboration in multidisciplinary scientific teams.

·         Strong oral and written communication skills, evidenced by peer-reviewed publications or presentations.

Preferred Experience:

·         Experience with computational design of cyclic peptides, macrocycles, or non-canonical peptide representations (e.g., HELM notation).

·         Experience with DNA-Encoded Library analysis, combinatorial enumeration, or NGS selection data deconvolution.

·         Familiarity with molecular modeling and structure-based design tools (e.g., Schrödinger, MOE) to facilitate cross-talk with molecular modelers.

·         Experience deploying containerized workflows (Docker), version control (Git), and utilizing Linux/high-performance computing (HPC) environments.
