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—sometimes within hours, but it may also take months depending on project needs.

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