-----------------------------------------

NOTE

At 10x, there are two types of opportunities (inhouse-jobs at 10x excluded):

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 to get access to the 10x platform For AI Lab roles, we scout, review, and approve profiles for access to future project opportunities and once approved you will get access to the 10x platform.

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.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
