Bilingual Spanish STEM Expert (PhD) — AI Safety
Company: Mercor · Pay: $58–$62/hr · Location: Remote — Western Europe · Type: contractor, part time · Languages: Spanish · Posted: 2026-09-14
Job Description Summary: We are hiring PhD-level scientists proficient in both English and Spanish to train and evaluate frontier AI models for safety, technical accuracy, and domain-specific robustness. No prior coding or machine learning background is required—your advanced scientific domain expertise is what matters most.
Unlocking the Future of AI: Why PhD Scientists Are Leading the Charge in AI Safety
Artificial Intelligence is no longer just a futuristic concept confined to research papers; it is actively reshaping science, education, industry, and daily life. However, as large language models (LLMs) and generative artificial intelligence systems become more powerful, the demand for rigorous safety measures, ethical guidelines, and domain-specific accuracy has skyrocketed. Technology laboratories and frontier AI companies face an unprecedented challenge: ensuring that models can navigate complex, sensitive scientific topics without hallucinating dangerous, inaccurate, or dual-use information.
This is where specialized intellectual talent steps in. Platforms like Mercor are bridging the gap between cutting-edge tech innovators and top-tier global academics. If you hold or are pursuing a PhD in fields such as chemistry, biology, molecular science, or related technical disciplines—and possess native or near-native fluency in both Spanish and English—an extraordinary remote career opportunity awaits you.
Detailed Breakdown of the Role and Responsibilities
The Bilingual Spanish STEM Expert (PhD) — AI Safety position is meticulously designed for high-level researchers who want to leverage their hard-earned academic credentials outside of traditional laboratory or tenure-track environments. Rather than performing bench research, your intellectual capital is deployed to audit, stress-test, and refine artificial intelligence systems.
Core responsibilities in this project include:
- Expert Prompt Generation: Crafting rigorous, advanced-level prompts in Spanish targeting specific, intricate scientific domains. These prompts challenge the model to process complex technical queries accurately.
- Response Evaluation & Annotation: Systematically reviewing and grading AI outputs for scientific validity, helpfulness, tone, and safe handling of sensitive dual-use material.
- Protocol Enforcement: Applying robust, structured classification guidelines to categorize user interactions and model behavior across specialized topics.
- Cross-Lingual Quality Assurance: Ensuring that complex technical concepts translate seamlessly between English research standards and Spanish linguistic nuances without losing technical integrity.
Ideal Candidate Profile and Qualifications
Mercor looks for specific, elite markers of competence when filling this role. Because the work directly influences the safety rails of next-generation models, candidates must demonstrate distinct subject-matter authority:
- Academic Background: A completed or ongoing PhD in chemistry, biology, microbiology, virology, genetics, or closely aligned scientific subfields.
- Linguistic Mastery: Native or near-native fluency in Spanish, paired with professional, business-level written English proficiency.
- Subfield Specialization: Deep familiarity with modern laboratory protocols, computational techniques, organic or inorganic synthesis, or specialized technical safety frameworks.
- Sound Judgment: Exceptional critical thinking and ethical awareness regarding dual-use research, biosafety, biosecurity, and hazardous material oversight.
Preferred Preference: While global applicants are welcome to apply, candidates based in Spain or the wider Western Europe region are given a logistical preference for operational alignment.
Understanding Compensation, Contracting, and Flexibility
One of the most compelling aspects of joining this initiative through Mercor is the transparency and competitiveness of the compensation package. Earning between $58 and $62 per hour as an independent contractor provides elite compensation that respects your advanced academic training.
Key highlights of the contracting structure include:
- Complete Autonomy: Enjoy fully remote work that you can structure around your personal schedule, research commitments, or other professional endeavors.
- Reliable Global Payouts: Weekly disbursements are processed seamlessly through reliable financial rails like Stripe and Wise.
- Zero Proprietary Conflict: Your project work remains cleanly separated from your primary employment, academic institution, or confidential client obligations.
The Broader Impact: Shaping Safe AI Standards
Participating in AI red-teaming and safety alignment offers a rare vantage point into the evolution of global technology. When you annotate and evaluate model responses, you are directly preventing the propagation of scientific misinformation and strengthening global safety frameworks. Tech labs rely heavily on human-in-the-loop expert feedback to ensure that future innovations remain ethical, robust, and aligned with human values.
Step-by-Step Guide to Completing Your Application
Securing a high-paying, flexible role requires moving through the application pipeline efficiently. Because positions with competitive rates like $58–$62/hr attract significant global attention, candidates are encouraged to complete their submissions promptly.
Follow these steps to maximize your application success:
- Prepare Your Documentation: Ensure your CV or resume clearly highlights your PhD status, specific scientific subfield, research history, and bilingual capabilities.
- Highlight Specialized Competence: Emphasize any experience you have with technical peer review, scientific grading, safety evaluations, or complex writing.
- Submit Promptly: Early applicants often secure priority evaluation as project capacity fills up rapidly.
