What We Do
The Mindrift platform, launched and powered by Toloka, connects domain experts with cutting‐edge AI projects from innovative tech clients. Our mission is to unlock the potential of GenAI by tapping into real‐world expertise from across the globe.
Who we're looking for
We're looking for curious and intellectually proactive contributors who double‐check assumptions and play devil's advocate. Are you comfortable with ambiguity and complexity? Does an asynchronous, 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.
About the Project
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.
How to Get Started
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.
Requirements
You hold a Bachelor's or Master's Degree in Finance or related fields.
You have a professional experience in finance with a minimum of 3 years in relevant fields (e.g., investment firms, banks, consulting, financial institutions, ministries). Having CFA or any related globally recognized qualification is an advantage.

An experience in cross‐functional, applied, or international projects will be an advantage, especially if your expertise has been used in real‐world or consulting contexts.
Familiarity with tools such as Excel (advanced), R, Python, MATLAB, SQL.
Ability to write clearly and professionally, including explaining complex tasks in simple, structured language.
Ability to analyze and synthesize information from multiple sources and turn it into accurate, coherent outputs.
Creativity in designing realistic and engaging examples, cases, or workflows based on your domain knowledge.
Motivation to work with challenging, complex, but well‐defined guidelines, learn new methods, and strengthen domain‐specific skills.
You are ready to learn new methods, able to switch between tasks and topics quickly and sometimes work with challenging, complex guidelines.
Our freelance role is fully remote, so you just need a laptop, internet connection, time available and enthusiasm to take on a challenge.
