Fractional Chief Technology Officer - AI Trainer
Department: Technology & Product
Location: The Netherlands
Compensation: €150 – €250 per hour
Employment Type: Contract
Updated: 12 March 2026
Freelance | 8–20 hrs/week | Remote (EU/UK)
Are you a Fractional CTO who wants to apply your technology leadership experience in a new way?
Do you have 8 to 20 hours per week available alongside your client portfolio, advisory roles or board commitments?
We are looking for experienced Fractional CTOs 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 improve large AI systems.
Your role is practical and high impact. You will:
Review and refine AI generated responses related to technology strategy, architecture and scaling
Evaluate outputs for technical soundness, feasibility and real world execution risk
Draft complex technical scenarios such as platform scaling, cloud architecture decisions, build versus buy trade offs, security architecture, technical debt management or digital transformation
Create variations of the same scenario from different stakeholder perspectives such as CTO, CEO, product leader, engineering manager or board member
Identify weaknesses in system design logic, architectural assumptions, roadmap prioritisation or delivery risk
In simple terms:
You will assess and improve AI generated content to ensure it reflects real world CTO level thinking, technical depth and execution awareness.
This is not hands on engineering work. Instead of building or managing one company’s technology stack, you will help improve how AI systems understand and reason about technology leadership at scale.
Your input directly improves how AI performs on technology strategy and architectural decision making topics.
Who this is for
You are:
A current or former Fractional CTO, CTO or senior technology leader
Based in the EU or UK
With significant experience leading engineering teams, defining technical strategy and scaling technology organisations
Experienced in areas such as cloud infrastructure, software architecture, DevOps, cybersecurity, platform design, product technology alignment or enterprise systems
Comfortable identifying unrealistic technical assumptions, architectural flaws and overlooked execution risks
Available 8 to 20 hours per week
Able to start in the coming weeks
This role is fully remote and flexible.
It works well alongside your existing client engagements.
