- A PhD (completed or in final stages) in one of the following fields: Machine Learning / AI, Computer Science, Engineering, Statistics, or a closely related quantitative subdomain such as Mathematics or Physics
- Strong analytical and critical-thinking skills, with the ability to spot subtle errors in technical reasoning
- Fluent written English and the ability to communicate complex ideas clearly
Nice to Have
- Research experience (academic or industry)
- Prior experience with data annotation or AI model evaluation
- Experience reviewing or publishing research papers
