ML Engineer - AI Trainer - Freelance - 8-20 hrs/week - Remote

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

Are you an experienced ML Engineer eager to apply your expertise in a new and impactful way? Do you have 8 to 20 hours per week available to contribute alongside your current projects or employment?

We are looking for top-tier machine learning professionals based in the EU or UK to help improve advanced AI systems.

What You’ll Be Doing

We are 10x.team, a platform for fractional and freelance professionals. We partner with leading AI labs to enhance large AI systems.

Your Role Is Hands-on And High Impact. You Will

• Review and refine AI generated outputs on a variety of machine learning and AI topics
• Evaluate responses for technical accuracy, ML best practices, and compliance with industry standards
• Draft realistic ML engineering scenarios, including model evaluation, deployment approaches, data pipeline design, scaling challenges, interpretability, and ethical considerations
• Create variations of the same scenario from different roles, such as ML engineer, data scientist, business stakeholder, or compliance advisor
• Identify gaps, misinterpretations, or oversimplified reasoning in AI generated content
• Assess and improve AI reasoning around structured problem solving, edge cases, and application of theoretical concepts
  
  

In Simple Terms

You will assess and improve AI generated content by ensuring it reflects the reality of ML engineering practices and challenges.

This is not a traditional engineering role. Instead of building models for individual use cases, your expertise will guide how AI systems understand and reason about ML topics at scale. Your feedback will directly improve how AI performs for technical users worldwide.
