Job Description Position Overview:

The PrincipalMachine Learning Scientist II will advance deep learning methods for biologics discovery at AbbVie. This individual contributor role focuses on advancing sequence- and structure-based deep learningmodelsfor protein and antibody designwith emphasis on adapting them to the constraints of designing therapeutic antibodies.

The work centers on building models that improve early decision-making in molecule prioritization andguidemoleculeoptimization,while balancingmultiple properties,in orderto reduce drug discovery timelines and increase the probability of successin patients. A major focus of the role is extending protein modeling to supportthe complexitiesofbiotherapeutics, includingcomplexmultispecificformats,sequence diversity, conformational flexibility, and induced-fit behavior, whichpresent importantmodeling challenges and opportunities for innovation. The role requires close collaboration with antibody engineers, computational physicists, and biologists to translatedomain conceptsintomodelingdecisions that will drive therapeuticimpact.

Responsibilities:

Advance sequence- and structure-conditioned generative modeling for biologics using protein language models, diffusion-based generative models, and graph- and geometry-based deep learning methods. Develop modeling strategies that improve therapeutic relevance, support multi-objective optimization, and surface liabilities earlier in the discovery process. Develop predictivemodeling approaches for multispecific biologics that optimize chain-complexation states, linker architecture, and higher-order molecular geometry toidentifydesigns with favorable efficacy and developability. Adapt protein models to CDR H3 loop behavior, including high diversity, conformational flexibility, and induced-fit effects. Build rigorousinternalbenchmarking frameworks, establish evaluation standardsfor external AI/ML platforms, and lead technical due diligence on partner capabilities. Use interpretability methods to uncover missing biological concepts, guide targeted model improvements. Partner with deployment engineers to deliver scalable, stable production modelsand model monitoring workflows. Qualifications MSwith 14+yearsorPhDwith 8+yearsinmachine learning, computer science, applied mathematics, data science, computational biology, or a closely related field, 2+ years of experiencebuildingmodels with biological data. Deep expertise in modern deep learning methods, including transformers, graph neural networks, protein language models, diffusion models, or related architectures. Experience applying ML to sequence-based and structure-based biological problems. Strongtrack recordof adapting models to complex, real-world scientific constraints. Ability to reasonaboutopen-ended technical problems and define a path forward in ambiguous settings. Strong python programming skills and familiarity with modern MLtools and frameworks, including distributed training workflows. Ability to collaborate effectively with experimental and computational scientists. Ability to communicate technical tradeoffs clearly across disciplines.
