Biochemistry and Life Sciences Researcher for AI Model Evaluation

Help improve how frontier AI models reason about real-world life sciences research. In this senior, hands-on role, you will apply deep scientific judgment to evaluate research tasks and model outputs, define rigorous standards for correct answers, and build benchmarks that measure meaningful model improvement.

• Review life sciences knowledge-work tasks and model outputs, identifying missing behaviors, weak reasoning, mechanistic oversimplification, unsupported causal claims, and responses that would not withstand peer review.
• Write detailed instruction specifications, create gold-standard solutions to life sciences problems, and define tasks that reflect real research practice.
• Design challenging domain-specific evaluation sets and contribute to life sciences skills and tools with the research team.
• Partner with researchers and adjacent-domain specialists to calibrate consistent quality standards and translate expert scientific judgment into explicit, teachable criteria.

• PhD in biochemistry, molecular or cell biology, genetics, immunology, neuroscience, or a closely related life science field.
• At least 4 years of substantive research experience at a recognized research university, academic medical center, national laboratory, or industrial research organization. Graduate coursework alone does not qualify.
• Deep specialization in at least one area, such as molecular and cell biology, biochemistry and structural biology, immunology and immuno-oncology, genetics and genomics, neuroscience, or systems biology.
• Demonstrated senior-level progression, such as Senior Scientist, Staff Scientist, Research Scientist, Instructor, Principal Investigator, or faculty appointment, with ownership of research direction.
• Peer-reviewed publication record, preferably including first-author publications in strong journals.
• Practical experience using large language models in professional work and the ability to distinguish sound reasoning from plausible but incorrect responses.
• Excellent written communication skills and the ability to provide precise, well-structured feedback.

• Full-time W-2 employment, with placement on an AI lab''s extended workforce and close collaboration with its internal research teams.
• Initial commitment of 6 months at 40 hours per week.
• Hybrid role based in the Bay Area, California, with on-site work alongside the client team multiple days per week when required.
• This is not a remote role. Candidates who do not currently live in the Bay Area must relocate at their own expense before the engagement begins. Relocation assistance is not available.
• Client-issued accounts and equipment will be provided, and work will be performed in the client''s tools and workflows.

$65 to $105 per hour.
