At Mindrift, innovation meets opportunity. We believe in using the power of collective intelligence to ethically shape the future of AI.

The Mindrift platform connects specialists with AI projects from major tech innovators. Our mission is to unlock the potential of Generative AI by tapping into real-world expertise from across the globe.

We’re looking for curious and intellectually proactive contributors, the kind of person who double-checks assumptions and plays devil’s advocate.
Are you comfortable with ambiguity and complexity? Does an async, remote, flexible opportunity sound exciting? Would you like to learn how modern AI systems are tested and evaluated?

This is a flexible, project-based opportunity well-suited for:

• Analysts, researchers, experienced professionals and consultants with strong critical thinking skills.
• People open to a part-time and non-permanent opportunity.

You will create complex, realistic tasks that push frontier AI agents to their limits. Think scattered data, conditional procedures, and genuine domain expertise required. You’ll build a detailed version with objective scoring, then write an ambiguous version intended to train the agent to succeed with less hand-holding. Real expert complexity only. You’re improving the AI tools you’ll eventually use yourself.

Apply to this post and get the chance to contribute to projects aligned with your skills, on your own schedule. To begin working in production, you’ll need to complete the qualification step and project onboarding, where you’ll get familiar with the guidelines interface and try your first real task with guidance from our quality team. From creating training prompts to refining model responses, you’ll be directly shaping how useful these models become for your own future work.

• Postgraduate or four-year bachelor's degree (BS, MSc, M, PhD) from reputable universities with a strong GPA (3.5-4).
• Professional industry experience in accounting with a minimum of 3 years in relevant economics fields (Economics Experts, Analysts, researchers, or consultants).

• Proven ability to use English fluently in professional settings, written and verbal (C1/C2 level).
• Access to a laptop, stable internet connection, and sufficient availability to engage with project tasks.
• Motivation to work with challenging, complex, but well-defined guidelines, learn new methods, and strengthen domain-specific skills.
