Job description

***This opportunity is intended for experienced Senior Python Engineers only****

Open to candidates in the North America, South America, Asia and Europe.
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.

What this opportunity involves

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 - You must meet all the requirements in order to be considered for this project:

5+ years of professional experience with Python.
Strong experience with FastAPI, pytest, and async/await.
Hands-on experience with Docker, PostgreSQL, and CI/CD pipelines.
Proven experience writing and maintaining automated tests (not just executing them).
Full-stack experience with React and TypeScript is a plus.
English proficiency at B2 level or higher.
Availability to work 30+ hours per week.

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.

How it works

Apply Pass qualification(s) Join a project Complete tasks Get paid

Hiring & Onboarding Process

The process is designed to move quickly and typically includes the following steps:

App review and invitation to a virtual project introduction session (approximately 30 minutes)
Platform registration and identity verification
Technical assessment (approximately 35 minutes)
Background check (completed at no cost to candidates)
Onboarding and project-specific training tasks
Begin production work!

Additional Requirements

Willingness to complete identity verification as part of the onboarding process.
Ability to complete a technical assessment.
Willingness to join and participate in Discord, which will be used for project communication and updates.
Successful completion of a background check is required prior to onboarding.
Reliable internet connection and ability to communicate effectively in a remote environment.
