- Create scenario variations from different stakeholder perspectives such as finance manager, executive team, or auditor

In simple terms: You will assess and improve AI-generated content to ensure it reflects real-world finance and controlling standards, practices, and reasoning. Your work will help scale and advance the quality of AI systems in the finance domain.

Who this is for

You are:

- A finance professional, controller, accounting specialist, or similar
- Based in the EU or UK
- With several years of experience in finance, accounting, or business analysis
- Skilled with modern financial tools, IFRS/local GAAP, and best practices

- Available 8 to 20 hours per week
- Able to start in the coming weeks

This role is fully remote and flexible—perfect alongside your existing commitments.

- Clear project scope and structured onboarding
- Potential for long-term collaboration based on performance

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. -----------------------------------------

## NOTE

At 10x, there are two types of opportunities:

1. Traditional freelance missions These are regular project-based opportunities where the listed mission is the actual project you may work on.
2. 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.
