Updated: 20 March 2026
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.
Who We’re Looking For
You are:
A software engineer, developer, architect, or senior technical contributor
Based in the EU or UK
Experienced in professional software development (several years)
Skilled in backend or frontend development, cloud infrastructure, distributed systems, DevOps, security, or system architecture
Comfortable spotting flawed logic, scalability concerns, and unrealistic technical assumptions
Available for 8 to 20 hours per week
Ready to start in the coming weeks
This is a fully remote and flexible engagement, ideal to balance with your existing commitments.
Why Join Us?
Flexible hours
100% remote
Opportunity to apply your engineering expertise to AI
Make a measurable impact on widely used AI systems
Structured onboarding and clear project scope
Potential for long-term collaboration, based on performance
Screening Process
Our process is efficient and fully guided:
Short AI-based interview
Brief technical evaluation focused on engineering reasoning
Compliance check to verify identity and professional background
After a successful selection and onboarding, you’ll be eligible to start on upcoming projects as they become available.
