Marketing & Sales Specialist - Freelance AI Trainer Project
About the role
Are you a marketing and sales expert eager to shape the future of AI? Large‑scale language models are evolving from clever chatbots into powerful engines of business insight and customer engagement. With high‑quality training data, tomorrow’s AI can democratize world‑class marketing strategies, keep pace with emerging market trends, and streamline sales processes for professionals everywhere. That training data begins with you - we need your expertise to help power the next generation of AI.
We’re looking for marketing and sales specialists who live and breathe market research, brand strategy, customer segmentation, digital marketing, sales funnel optimization, lead generation, CRM management, competitive analysis, content marketing, and sales forecasting. You’ll challenge advanced language models on topics like campaign planning, buyer behavior analysis, product positioning, social media strategies, sales enablement, and pipeline management - documenting every failure mode so we can harden model reasoning.
On a typical day, you will converse with the model on marketing scenarios and sales strategy questions, verify factual accuracy and logical soundness, capture reproducible error traces, and suggest improvements to our prompt engineering and evaluation metrics.
A bachelor’s or master’s in marketing, business, communications, or a closely related field is ideal; proven track records in marketing campaigns, sales achievements, or hands‑on CRM projects signal fit. Clear, metacognitive communication - “showing your work” - is essential.
Ready to turn your marketing and sales expertise into the knowledge base for tomorrow’s AI? Apply today and start teaching the model that will teach the world.
We offer a pay range of $6-to- $65 per hour, with the exact rate determined after evaluating your experience, expertise, and geographic location. Final offer amounts may vary from the pay range listed above. As a contractor you’ll supply a secure computer and high‑speed internet; company‑sponsored benefits such as health insurance and PTO do not apply.
