Preclinical R&D Scientist, ADC & Bispecifics, for AI Model Training

Apply hands-on preclinical drug-development expertise to help improve AI models for chemistry, materials science, and drug discovery. This remote opportunity combines wet-lab and translational R&D experience with scientific data review, annotation, and expert input across antibody-drug conjugate and bispecific programs. Key Responsibilities

• Review technical materials and real-world R&D data from ADC and/or bispecific programs.
• Label, classify, and annotate scientific data and model outputs to improve model performance.
• Advise on scientific and development decisions, including target and modality selection, optimization, trade-offs, and risk.
• Help establish structure and quality standards for a scientific dataset pipeline.
• Participate in expert discussions, interviews, and research engagements.
• Work directly with the client team.

• Hands-on, non-administrative preclinical R&D experience at a company that develops drug assets in-house and has advanced programs to the clinic.
• Direct experience with ADCs and/or bispecific or multispecific antibodies.
• Experience in a core R&D function, such as discovery biology, medicinal chemistry, protein or antibody engineering, computational science, in vivo or translational research, pharmacology or PK-PD, toxicology, or CMC or formulation.
• 5+ years of relevant industry R&D experience, with flexibility based on depth of experience.
• Experience advancing a program through lead optimization or IND-enabling and preclinical development is preferred.
• Experience at a mid-sized, emerging, or resource-constrained biotech is preferred, ideally with current experience outside a top-20 pharmaceutical company.

This role is intended for hands-on preclinical R&D professionals, from individual contributor through Director level. It is generally not suited to candidates whose work is primarily CRO or CDMO services, academic-only research, QC or analytical work, clinical development only, diagnostics, or regulatory or medical writing.

• Remote, hourly engagement.
• Part-time schedule of roughly 10 hours per week.

$60 to $100 per hour.
