# Freelance Agent Evaluation Engineer

> Mindrift · Ireland (Remote) · Part-time · Posted 2026-08-17

**Workplace:** remote

**Department:** English_HackerRank

## Description

_Please submit your CV in English and indicate your level of English proficiency._

  
Mindrift connects specialists with project-based AI opportunities for leading tech companies, focused on testing, evaluating, and improving AI systems. **Participation is project-based, not permanent employment.**

  
We're building a dataset to evaluate AI coding agents - how well a model handles real-world developer tasks.

You'll create challenging tasks and evaluation criteria within realistic simulated environments:

-   Build realistic developer environments - a virtual company with codebase, infrastructure, and context (tickets, docs, conversations) that forms a believable development history
-   Design tasks from intermediate states of these environments - craft the prompt, define what "solved" means, and ensure the task is solvable by an AI agent
-   Write tests that verify agent solutions - accept all valid approaches and reject incorrect ones, neither too strict nor too lenient
-   Iterate on tasks and tests based on QA feedback - review agent solutions, analyze failures, and refine until the evaluation is fair and robust

**What this is NOT:**

-   Not data labeling
-   Not prompt engineering
-   Not writing code from scratch - the agent writes most of the code; you guide and evaluate

**What we look for:**

-   5+ years in software development
-   Core stack: Python (FastAPI), JavaScript/TypeScript (React), Docker, Postgres, Kafka, Redis
-   Experience writing tests (functional, integration)
-   English proficiency - B2+

**Why this is hard:**  
Frontier models are already good at coding. Creating a task that genuinely challenges the best models is non-trivial. You need to deeply understand where models fail and what scenarios reveal the difference between a good and a bad solution. Tasks have many valid solutions - writing tests that accept all correct solutions and reject incorrect ones is harder than it sounds.

**Requirements and benefits**

_**Educational qualifications**_

-   A Master’s Degree in Computer Science, Software Engineering, Data Science / Data Analytics, Artificial Intelligence / Machine Learning, Computational Linguistics / Natural Language Processing (NLP), Information Systems or other related fields.
-   Bachelor’s degree is accepted if only candidate has 5 years of experience in the field.

_**Academic and/or Professional Experience**_

Candidates should have a minimum of 3 years of professional experience in related roles or domain - specifically for QA-automation/testing or cybersecurity roles

**How it works**  
Apply → Pass qualification(s) → Join a project → Complete tasks → Get paid

**Compensation:**  
Paid per accepted task. Your rate depends on the qualification tier you reach and how efficiently you complete tasks — up to the equivalent of **$50/hr**. Because payment is per task, a faster pace raises your effective hourly rate.

**Why this freelance opportunity might be a great fit for you?** 

-   Take part in a part-time, remote, freelance project that fits around your primary professional or academic commitments.
-   Work on advanced AI projects and gain valuable experience that enhances your portfolio. - Influence how future AI models understand and communicate in your field of expertise.
