Mechanical Engineering Expert

About this role

**Join a growing network of industry experts supporting AI research and development.** # Overview We're building a select group of experienced mechanical engineers to help evaluate and improve how AI systems understand and reason about mechanical engineering topics. You'll bring your real-world expertise to review content for accuracy, answer domain-specific questions, and share feedback that helps make AI tools more reliable and useful in mechanical engineering contexts. This is a flexible, part-time engagement — approximately **10 hours per week**, fully remote, with the opportunity to continue and grow over time. # What You'll Do - Review and evaluate written content and AI-generated responses in your area of mechanical engineering expertise for accuracy and quality. - Answer questions and provide clear, well-reasoned feedback based on your professional experience. - Help identify useful reference material relevant to your field. - Share insight into how mechanical engineers actually work — the tools, workflows, and standards you rely on day to day. - Collaborate with a small group of other subject-matter experts across different fields. # What We're Looking For - Degree-qualified mechanical engineer holding a Professional Engineer (PE) license in the US. - 2+ years of professional mechanical engineering experience, ideally across more than one area (thermodynamics/HVAC, structural/mechanical design, manufacturing). - Familiarity with relevant codes and standards (e.g. ASME) and common engineering tools (SolidWorks, ANSYS, AutoCAD, or similar). - Some experience writing technical documentation, specs, or training material is a plus. - Comfortable using everyday AI tools (e.g. ChatGPT or similar). - Based in the United States. - Professional working English. - Able to commit reliably to about 10 hours per week. **About Cincinnatus LLC:** Cincinnatus LLC is an enterprise staffing company that partners with leading technology companies to source and employ highly skilled professionals for contingent and contract-based opportunities.
