Software Developer — Build Your Own Project with an AI Coding Assistant

About the Role

What if you could get paid to work on the project you've been meaning to build — with a state-of-the-art AI coding assistant at your side, completely free of charge?

We're looking for software developers in Barcelona to bring their own projects and build them using an AI-powered coding assistant. You write real code on real projects you care about. We learn from your expert judgment on how the assistant performed. You keep full ownership of everything you build.

This is a fully remote, flexible contract role designed for developers who want to ship their own work — and get compensated for it.

Organization: Alignerr
Type: Hourly Contract
Location: Fully Remote
Commitment: Flexible

What You'll Do

Bring a software project you personally own — a side project, a tool, an open-source library, or something you've been meaning to finish
Build features, fix bugs, refactor code, write docs, or do whatever your project needs — using an AI coding assistant
At each step, compare two versions of the assistant's response, choose the better one, and write a brief explanation of your reasoning
Work in your own environment, on your own schedule, with your own tools

Who You Are

A developer with a software project you personally own, stored in a git repository
Comfortable working in the terminal and with git-based workflows
Running macOS, Linux, or Windows with WSL2
Able to write clear, honest evaluations — you'll explain your choices in a few sentences
Self-motivated and reliable when working independently
Open-source maintainers are especially welcome

What's Eligible

Software projects that you personally and solely own
Open-source projects with an approved license
If your project has other maintainers, mention it in your application — we'll confirm eligibility

What's Not Eligible

Work owned by an employer, client, university, company, or startup
Projects under NDA
AI model training or evaluation projects; ML infrastructure
Security exploit tooling
Projects that process other people's personal data

Good to Know

Before starting, you'll sign short contributor terms and we'll approve your project
Transcripts of your coding sessions are used to improve AI models and cannot be withdrawn after submission — this covers sessions only, not the rest of your codebase
Your ratings and written feedback become part of the project's deliverables
During sessions: no passwords, API keys, or other people's personal data — and you write your ratings yourself, without AI help

Why You'll Love This

Your project, your code — you keep full ownership of everything, including code the assistant writes for you
Free AI tokens — your AI usage during sessions is fully covered, no subscription or API bill needed
Paid to build what you'd build anyway — real compensation for real development work on your own project
Fully remote and flexible — work from your own computer, on your own schedule
Shape the future of AI-assisted coding — your expert judgment directly improves the next generation of developer tools
Spots are limited — the first cohort is small and starting soon
