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

Are you an experienced accountant who can spot errors in financial reasoning and understands the true complexities of real‑world accounting? Do you have 8 to 20 hours per week available alongside your primary role or freelance projects? Join us in shaping how AI learns from and applies authentic accounting expertise at scale.

About The Role

10x.team connects expert freelancers with leading AI labs building next‑generation models. We are looking for experienced accountants based in the EU or UK to help enhance the depth, accuracy, and practicality of AI‑powered financial and accounting systems.

What You Will Do

• Review and refine AI‑generated outputs covering accounting topics such as financial reporting, tax, audits, compliance, and bookkeeping
• Evaluate AI responses for accuracy, realism, and adherence to accounting standards
• Draft realistic accounting scenarios and case studies drawn from your experience
• Identify omissions, inaccuracies, or flaws in AI‑generated financial content
• Create alternative perspectives from roles such as auditor, financial controller, tax advisor, or business owner

In Simple Terms

You will assess and improve AI‑generated accounting content to ensure it demonstrates real best practices and a nuanced understanding of professional accounting. Rather than delivering traditional accounting services, you’ll apply your expertise to help AI systems truly understand accounting complexities in real use cases.

Who You Are

• A qualified accountant (e.g. ACA, ACCA, CIMA or equivalent), financial controller, or accounting advisor with significant hands‑on experience
• Based in and eligible to work in the EU or UK
• Several years of hands‑on experience in areas such as financial reporting, tax compliance, audit, or business accounting
• Strong ability to spot mistakes, unrealistic scenarios, or flawed logic in accounting and finance content
• Comfortable working independently and providing clear, actionable feedback
• Available for 8–20 hours per week, with near‑term start

Why Join?

• Flexible, fully remote work aligned with your current commitments
• Apply your accounting expertise in an innovative, high‑impact AI environment
• Directly shape the next generation of AI accounting tools and systems
• Access to clear briefs, supportive onboarding, and the chance for ongoing collaboration

How To Apply

After applying, you’ll receive an email detailing the steps to:

• Complete a short written assessment
• Participate in an AI‑powered interview

Important: Your application is only complete once you finish all steps via the email link.

Please note: these AI Lab missions are not traditional job openings with fixed start dates. Project demand is highly dynamic and matching depends on your expertise, availability, and current AI Lab needs. Some experts are matched within days, while others may wait longer for a suitable project.

Once onboarded, you’ll be eligible to start on upcoming projects as they become available.

Join us and help build the accounting expertise within the world’s most advanced AI models!

NOTE

At 10x, There Are Two Types Of Opportunities

• Traditional freelance missions. These are regular project‑based opportunities where the listed mission is the actual project you may work on.
• AI Lab roles. For AI Lab roles, we scout, review, and approve profiles for access to future project opportunities.

The missions listed for AI Lab roles are not traditional job openings. AI Lab work is often highly confidential as this exposes information of what an AI Lab is working on, and project requests are unpredictable. When an AI Lab request comes in, we often need to respond within 24 hours with suitable talent.

Matching depends on the specific needs of each AI Lab project and your niche expertise. Once your profile is reviewed and approved, you may be matched to relevant AI Lab projects when suitable opportunities arise.

This can happen within hours, but it may also take months, depending on the researchers at the AI labs and their project needs.
