Software Engineer - AI Trainer - Remote - 8-20hrs week - Freelance

Freelance | 8–20 hrs/week | Remote (EU/UK)

Are you a software engineer eager to apply your expertise in a fresh, impactful way? Do you have 8 to 20 hours per week available alongside your current role or freelance work?

10x.team is seeking experienced software engineers based in the EU or UK to help advance cutting-edge AI systems.

About Us

10x.team is a platform for fractional and freelance professionals partnering with leading AI labs to enhance large-scale AI systems.

What You’ll Do

In this role, you’ll make a tangible impact by:

* Reviewing and refining AI-generated responses related to software development and system design

* Evaluating outputs for technical accuracy, code quality, and architectural integrity

* Drafting realistic engineering scenarios (API design, distributed systems, performance optimization, refactoring, debugging, and more)

* Creating scenario variants from the perspectives of backend, frontend, DevOps engineers, architects, or engineering managers

* Identifying weaknesses in logic, edge case handling, scalability assumptions, and security practices

In simple terms: You’ll assess and improve AI-generated content to make sure it aligns with real-world engineering standards, robust system design, and clean code principles.

This is not a hands-on product development role. Rather than building a specific product, you’ll contribute to how AI understands and reasons about software engineering at scale. Your expertise will shape how AI excels at programming, architecture, and technical problem-solving.
