1. Role Overview Mercor is collaborating with a
leading AI lab on a large-scale AI training initiative focused on
improving transportation systems reasoning, infrastructure
analysis, and logistics planning capabilities in advanced language
models. We’re seeking experienced Transportation professionals to
contribute by creating and evaluating transportation-related
prompts and responses. This is a multilingual opportunity. We are
specifically seeking experts who are fluent and professionally

regulatory alignment, and clarity Write high-quality human-authored
“gold” responses for complex transportation planning or operational
scenarios Create controlled prompt variations that test subtle
differences in regulatory environments, geographic constraints,
demand patterns, safety requirements, or system design assumptions
Evaluate outputs across different tones (technical,
policy-oriented, operational, explanatory) and instruction




constraints Identify model failure cases involving unrealistic
system design, regulatory misinterpretation, flawed logistical
reasoning, or safety oversights 3. Adecuado Qualifications Degree in
Transportation Engineering, Civil Engineering, Urban Planning,
Logistics, Supply Chain Management, or a closely related field (or
equivalent professional experience) 2+ years of professional work
