Preclinical R&D Expert – In-house Drug Development | $85-$142/hr Remote
Overview
An AI lab backed by venture capital is building physics-based foundation models for chemistry, materials science, and drug discovery. The lab works with Mercor to bring in hands-on preclinical R&D experts who guide how AI systems interpret real pharmaceutical data. This remote contract runs about 10 hours per week and pairs bench-level scientific judgment with data annotation work. Your feedback on drug development decisions and data quality shapes how models reason about new medicines.
What You'll Do5
- 1Examine technical documents and actual R&D datasets drawn from your specialty area.
- 2Label and classify scientific data and AI model outputs to sharpen model accuracy.
- 3Advise on major scientific and development choices, including target or modality selection, optimization trade-offs, and risk.
- 4Shape the structure and quality requirements for the client's data pipeline.
- 5Join expert panels, interviews, and research sessions to inform platform direction.
Requirements6
- 1Hands-on, non-administrative preclinical R&D experience at a company that develops its own drug assets and has advanced programs to the clinic.
- 2Work in a core R&D function: discovery biology, medicinal chemistry, protein or antibody engineering, computational science, in vivo or translational work, pharmacology and PK/PD, toxicology, or CMC and formulation.
- 3Direct experience with one or more drug modalities such as small molecules, monoclonal antibodies, peptides, ADCs, bispecifics, mRNA, siRNA, ASOs, PROTACs, molecular glues, cell therapies, gene therapies, or radioligand therapies.
- 4At least 5 years of industry R&D experience, with flexibility for deeper expertise.
- 5Experience moving a program through lead optimization or IND-enabling preclinical development.
- 6Background in mid-sized, emerging, or resource-constrained biotech, ideally outside the top-20 pharmaceutical companies.
Who Should Apply
The ideal candidate has spent years at a biotech or pharma company doing hands-on preclinical work that moved molecules toward the clinic. You bring deep familiarity with a core R&D function and at least one drug modality, plus enough breadth to reason about trade-offs across target selection, optimization, and development risk. This role is not a fit for scientists whose experience is limited to CRO/CDMO services, academic research, QC or analytical work, clinical development, diagnostics, or regulatory and medical writing. A typical rejection reason is a lack of in-house drug development experience or no history of taking a program through lead optimization or IND-enabling studies. A common miss is failing to show how your scientific judgment applies to messy, real-world datasets rather than just to controlled experiments.
Salary Insight
Pay is $60 to $100 per hour for this ongoing part-time contract. That range suits experienced preclinical scientists from individual contributor to director level, and it reflects the senior advisory nature of the work plus the flexibility of a remote, 10-hour weekly commitment.
