Requirements
• You are an experienced software engineer with a strong track record of building and shipping production systems. • Minimum profile: • 5+ years of professional software engineering experience • Based in an EU or UK jurisdiction • Strong expertise in at least one area (e.g., backend systems, distributed systems, frontend/UI engineering, cloud infrastructure, DevOps/SRE, data engineering, mobile development, embedded systems, security engineering) • Proficiency in at least two major languages (e.g., Python, TypeScript/JavaScript, Java, Go, Rust, C/C++, C#, Kotlin) • Exceptional ability to reason about code correctness, performance, and architectural trade-offs • Ability to identify bugs, anti-patterns, and logical flaws quickly • Experience with system design at scale (microservices, event-driven architecture, distributed databases) • Experience mentoring engineers or conducting technical interviews • Familiarity with ML/AI infrastructure, LLM tooling, or AI-assisted development workflows • Open-source contributions or technical writing • Interest in AI and how models reason about code • What matters most: you understand how software engineering works in practice — not just writing code, but designing systems, making trade-offs, debugging under pressure, and shipping reliably — and you can break it down with precision. • Commitment & Structure • Asynchronous work (flexible scheduling — work in your own time) • 10–20 hours per week • Estimated duration: 2–4+ months (extension possible) • Independent contractor agreement • High-quality contributors may be invited to longer-term AI training initiatives.
Responsibilities
• 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 software development and system design • Evaluate outputs for technical correctness, code quality and architectural soundness • Draft realistic engineering scenarios such as API design, distributed systems challenges, performance optimisation, refactoring strategies or debugging complex issues • Create variations of the same scenario from different perspectives such as backend engineer, frontend engineer, DevOps engineer, architect or engineering manager • Identify weaknesses in logic, edge case handling, scalability assumptions or security considerations • In simple terms: • You will assess and improve AI generated content to ensure it reflects real world engineering practice, clean code principles and robust system design. • This is not hands on product development. Instead of building a specific application, you will help improve how AI systems understand and reason about software engineering at scale. • Your input directly improves how AI performs on programming, architecture and technical problem solving topics. • Who this is for • A software engineer, developer, software architect or senior technical contributor • Based in the EU or UK • With several years of professional software development experience • Experienced in areas such as backend or frontend development, cloud infrastructure, distributed systems, DevOps, security or system architecture • Comfortable identifying flawed code logic, scalability issues and unrealistic technical assumptions • 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 professional commitments. • A short AI based interview • A brief technical evaluation focused on engineering reasoning • A compliance check to verify your identity and professional background • If approved, you will be onboarded and can start shortly after.
Benefits
• €60 – €110 per hour • Work on Frontier AI Systems | Via 10x.team | Major AI Lab Partner • Work on Frontier AI Systems | Via • 10x.team • | Major AI Lab Partner • Location Requirement: Europe (EU + UK) • Location Requirement: • Competitive hourly rate (market-aligned for senior European software engineers) • Paid weekly via secure payment infrastructure • Performance and quality-driven continuation • You won't be shipping features for a single product. You'll be shaping how AI systems understand and reason about software engineering — system design, debugging logic, architectural trade-offs, and production-grade code — at scale. • This is applied expertise with global impact. • 10x.team • 10x.team is the ultimate fractional and freelance platform for top-tier professionals who deliver 10x outcomes. • We partner with ambitious companies and leading AI labs to deploy elite execution talent into high-impact missions — strengthening frontier AI models with real-world human expertise, structured reasoning, and professional judgment. AI doesn't improve with more data. It improves with better expertise. • We curate excellence. We prioritize outcomes. We move fast. • Application Process • Application Process • Complete a short expertise profile AI intake • Complete a finetuning sample • Shortlisted candidates receive next steps within a few days • If you operate at the top of your field and want to contribute to frontier AI development: apply.
