Contract

Careerflow Human Data Labs partners with AI companies to bring real-world professional expertise into their products.

**About the work**

We build hard, realistic tasks used to test how well AI agents do real work on a computer. Each task is a small scenario running on a Linux desktop — real files, real applications, real documents — plus a program that automatically checks whatever the agent produced.

You create those tasks end to end. The bar: hard for a top AI agent, straightforward for a competent human.

## **Responsibilities**

- Design a realistic multi-step scenario across a few applications.

- Put together the files it needs — spreadsheets, documents, emails, data. Sometimes supplied to you, sometimes built by you.

- Write the instruction the AI agent receives: clear, complete, no giveaways.

- Write Python to set up the environment and to score the result automatically.

- Test it, run it, and hand over short documentation.

## **What we are looking for**

- **Python** — comfortable writing and debugging real scripts.

- **Heavy AI user** — you work with AI coding tools and models every day and get genuinely good output from them.

- **Some AI / ML background** — worked on AI projects, at an AI company, or with agents and evaluations.

- **Ubuntu and virtual machines** — basic comfort. Everything runs on hosted Linux VMs, so you should be fine on a terminal and inside a Linux desktop.

- **Careful and detailed** — an unclear instruction or a sloppy check breaks the task.

- Git basics.

## **A strong plus**

- You have built **RL environments** before — anything where an agent acts and a program scores the outcome.

- You have built **tasks or benchmarks for computer-use agents** (agents that control a real desktop, browser, or operating system).

- You know **OSWorld** or similar computer-use benchmarks. Not required, but it means you will be productive on day one.

## **Payment and availability**

- **$50 USD per task**, paid once the task is accepted and approved in review.

- One free revision round if a task needs fixes.

- No cap on how many tasks you deliver — throughput is up to you.

- Must be available to start **the next day** and stay through the **3–4 week** window.

- Flexible hours, fully async. We ask for a daily check-in and feedback turnaround within about a day.
