Job Type: Flexible Contract (Remote), Mexico

Job Summary: We are hiring Biology Subject Matter Experts for a paid project with an AI lab that tests whether frontier AI models can handle expert-level biology. You will create hard questions and tasks from your field that a leading AI model cannot answer correctly, then review where and why it fails.

What you will do

- Write challenging, realistic problems based on real work in your area of biology. Examples:
- Interpret experimental results, such as a gel, a sequencing readout, a flow cytometry plot, a growth curve or a figure from a paper.
- Design or critique an experiment, including controls, sample size and sources of error.
- Analyze a dataset and draw the correct conclusion, such as a differential expression table, a phylogenetic tree or a population study.
- Reason through a mechanism in molecular biology, cell biology, genetics, ecology or physiology.
- Evaluate a claim from a published paper and identify flaws in its methods or statistics.
- Write a detailed reference answer for every problem, with the reasoning behind it and the sources you used.
- Write clear grading criteria so that answers can be checked consistently.
- Review a leading AI model’s attempt, explain where and why it went wrong, and adjust the problem until the model fails because the problem is truly hard, not because the question is unclear.

Who we are looking for

- A PhD in biology or a related field, such as molecular biology, cell biology,



genetics, microbiology, ecology, neuroscience, biochemistry or bioinformatics. PhD candidates and students are welcome to apply.
- Research or industry experience in your area of biology.
- At least one publication, academic or professional, is preferred.
- Experience teaching, peer reviewing, or writing exam questions or technical assessments is an advantage.
- Experience with data analysis in Python or R is a plus.
- Strong written English and the ability to explain scientific reasoning clearly.
- Able to work independently in a remote setting.
- Based in Mexico.

Why Cobalt AI

- Advance frontier AI where it counts. Apply your expertise to the data frontier labs cannot get any other way, where your reasoning directly shapes how the next generation of models solves scientific problems.
- Grow professionally. Expand your influence through evaluation projects, advisory roles and research collaborations, while deepening your understanding of how frontier models are trained and assessed.
- Work with a top-tier network. Collaborate with researchers and scientists from leading institutions and labs on high-impact, flexible work.
- Set your own schedule. Fully remote and versátil, with hours that fit around your current role and your life.
- Competitive pay. Paid per accepted task, with higher rates for consistently strong work.
