About the role

Key responsibilities & impact

Serve as the scientific authority on ground truth for pathogen-countermeasure AI benchmarks
Build tasks covering antigen and immunogen comparison, epitope mapping, neutralization and cross-reactivity, antiviral susceptibility, and resistance interpretation
Write gold-standard answers from raw data with tolerances reflecting assay, replicate, and strain variability
Curate neutralization titers, binding and epitope maps, serology time courses, EC50 and dose-response curves, and viral sequences with resistance markers
Test whether AI agents distinguish real escape or resistance from assay artifacts
Evaluate whether agents separate binding from neutralization, immunogenicity from protection, and laboratory resistance from clinical relevance
Assess immune imprinting, waning, and cross-resistance when ranking candidates
Challenge conclusions that would not withstand a program review
Identify agent errors, expert alternatives, and evidence that would change the assessment
Reward explicit uncertainty over confident guesses
Collaborate with scientists and engineers to develop benchmark tasks and datasets
Participate in take-home, technical, culture, and background-check stages of the hiring process

Requirements

What you’ll need

3+ years of hands-on experience in either vaccine/antibody development or antiviral development, ideally in respiratory viruses (influenza, RSV, or coronaviruses)
Deep expertise in at least one of: vaccine antigen design, immunogen engineering, therapeutic antibody discovery, epitope mapping, neutralization, cross-reactivity, immune recognition, comparative candidate evaluation, antibody responses, immune imprinting, waning immunity, antiviral susceptibility and resistance, phenotypic drug-response and viral sequence data, antiviral discovery, mechanism-of-action studies, candidate evaluation, treatment-emergent resistance, cross-resistance, resistance-marker interpretation, assay development, validation, or dose-response analysis
PhD in immunology, virology, microbiology, or a related field, or equivalent industry experience
Personally analyzed data rather than only supervising it
Daily use of Claude, ChatGPT, or similar AI tools
Judgment to identify answers that are technically correct but scientifically wrong
Ability to overrule an AI agent and openness to update when shown wrong
For US employment, ability to work full-time as a W-2 employee; visa sponsorship is available for H-1B, O-1, and TN, with STEM OPT support
