AI Agent Evaluation Analyst (Freelance)
Mindrift · Barcelona, ES
Teletrabajo . QA
This opportunity is only for candidates currently residing in the specified country. Your location may affect eligibility and rates. Please submit your resume in English and indicate your level of English proficiency.
At Mindrift, innovation meets opportunity. We believe in using the power of collective human intelligence to ethically shape the future of AI.
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, 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, or consultants with strong critical thinking skills
- Students (senior undergrads / grad students) looking for an intellectually interesting gig
- People open to a part-time and non-permanent opportunity
We're on the hunt for QAs for autonomous AI agents for a new project focused on validating and improving complex task structures, policy logic, and agent evaluation frameworks. Throughout the project, you'll have to balance quality assurance, research, and logical problem-solving. This project opportunity is ideal for people who enjoy looking at systems holistically and thinking through scenarios, implications, and edge cases.
You do not need a coding background, but you must be curious, intellectually rigorous, and capable of evaluating the soundness and consistency of complex setups. If you've ever excelled in things like consulting, CHGK, Olympiads, case solving, or systems thinking — you might be a great fit.
What you'll be doing:
- Reviewing evaluation tasks and scenarios for logic, completeness, and realism
- Identifying inconsistencies, missing assumptions, or unclear decision points
- Helping define clear expected behaviors (gold standards) for AI agents
- Annotating cause-effect relationships, reasoning paths, and plausible alternatives
- Thinking through complex systems and policies as a human would to ensure agents are tested properly
- Working closely with QA, writers, or developers to suggest refinements or edge case coverage
Apply to this post, qualify, and get the chance to contribute to a project aligned with your skills, on your own schedule. Shape the future of AI while building tools that benefit everyone.
Requirements
- Excellent analytical thinking: Can reason about complex systems, scenarios, and logical implications
- Strong attention to detail: Can spot contradictions, ambiguities, and vague requirements
- Familiarity with structured data formats: Can read, not necessarily write JSON/YAML
- Ability to assess scenarios holistically: What's missing, what's unrealistic, what might break?
- Good communication and clear writing (in English) to document your findings.
- Experience with policy evaluation, logic puzzles, case studies, or structured scenario design
- Background in consulting, academia, olympiads (e.g. logic/math/informatics), or research
- Exposure to LLMs, prompt engineering, or AI-generated content
- Familiarity with QA or test-case thinking (edge cases, failure modes, "what could go wrong")
- Some understanding of how scoring or evaluation works in agent testing (precision, coverage, etc.)
- Get paid for your expertise, with rates that can go up to $30/hour depending on your skills, experience, and project needs
- Take part in a flexible, remote, freelance project that fits around your primary professional or academic commitments
- Participate in an advanced AI project and gain valuable experience to enhance your portfolio
- Influence how future AI models understand and communicate in your field of expertise

Requirements
- You hold a Bachelor's, Master's or PhD Degree in Statistics, Biostatistics, Econometrics and/or in a relevant area.
- You have professional experience in one of the following fields: Applied Statistics, Bayesian Statistics, Biostatistics, Econometrics, Economic Statistics, Experimental Design (DOE) & A/B Testing, Generalized Linear Models (GLMs), Hypothesis Testing, Machine Learning (e.g., Classification, Regression, Clustering), Probability Theory, Statistical Modeling, Time Series Analysis
- Your level of English is advanced (C1) or above.
- Expertise in statistical modeling and data analysis, including areas such as descriptive and inferential statistics, regression analysis, experimental design, and machine learning
- Proficiency in Python, with experience using libraries such as Pandas, NumPy, SciPy, Statsmodels, and Scikit-learn.
- Strong ability to design creative and diverse problems, particularly those that are computationally intensive and go beyond simple parameter modifications.
- 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
Why this freelance opportunity might be a great fit for you?
- Get paid for your expertise, with rates that can go up to $34/hour depending on your skills, experience, and project needs
