We enable leading pharmaceutical teams to discover and develop drugs faster. We host the industry’s largest federated data networks for drug discovery AI, spanning co-folding, ADMET, and antibody develop ability. Across these networks, models are trained on proprietary industry datasets to achieve higher performance and broader applicability while keeping data control and IP protected. We deliver these superior models through drug discovery applications that enable teams to run them at scale, further customize them, and integrate them into existing R&D workflows. AI Structural Biology (AISB) Network:Pharmaceutical companies collaborate in the field of co-folding, structure-based binding affinity predictions and antibody design.ADMET Network:Pharmaceutical and biotech companies collaborate to improve small-molecule property prediction and expand into further drug modalities.Antibody Develop ability Network:Pharma partners collaborate to federate historical and purpose-built antibody develop ability data sets for secure ML training, without data leaving each partner’s environment.About the roleWe are looking for a Forward-Deployed Cheminformatician to own how binding data is prepared across our co-folding focused networks and initiatives. Binding data is the input that decides whether our co-folding and binding-affinity models perform in real drug programs. It arrives from pharma partners in heterogeneous shapes - different assay registries, different metadata, different chemical-representation standards, different choices on qualifiers, replicates and censoring. We need someone who turns this into a repeatable, well-documented preparation pipeline that pharma representatives can run alongside us, and that scales to the public-data corpus we build for our own model training. This is half engineering, half forward-deployed work. You will define the protocol, harden it with validators and scripts, integrate it into the Apheris products, run it with each new partner, and own the equivalent pipeline for the public binding-data corpus.What you will doDefine and own the binding-data preparation protocol - data schema, small-molecule standardization, assay metadata model, value handling (KD, Ki, IC50, pIC50), qualifier and censored-value handling, duplicate and replicate aggregation.Build the tooling that runs it - modular scripts, validators with actionable errors, and reusable pipelines that survive different pharma upstream systems (Dotmatics, Spot fire, in-house registries).Work forward-deployed with pharma. Sit with their biologists and medicinal chemists, walk them through the protocol, sense-check what an assay column actually measures, and unblock retrieval.Maintain the small-molecule representation pipeline - RDK it standardization, tautomer and ionization handling, stereochemistry preservation, and PAINS / frequent-hitter filtering.Curate the public binding-data foundation - ChEMBL,BindingDB, PubChemBioAssay - prepared to the same standard, so our models train on the strongest public baseline anyone can assemble.Hand the productized pipeline cleanly to engineering for scaling, and partner with ML to keep the data contract valid as models and networks evolve.What we expect from youYou should apply if: You have a BSc, MSc, PhD or equivalent in cheminformatics, computational chemistry, or a related field, plus 3+ years preparing biological assay data in a discovery setting.You are fluent in Python andRDKit. SMILES normalization, tautomer / ionization / stereochemistry handling, and scaffold extraction are second nature, and you understand why each matters for activity cliffs and model training.You have hands-on experience curating quantitative binding assay data (KD, Ki, IC50, pIC50)...
