Traditional freelance missions
These are regular project-based opportunities where the listed mission is the actual project you may work on.
For AI Lab roles, we scout, review, and approve profiles for access to future project opportunities.
AI Lab work is often highly confidential as this exposes information of what an AI Lab is working on, and project requests are unpredictable. 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.
