Careers · Freelance

We're hiring freelance talent.

We're growing fast and looking for senior freelancers and small specialist teams to collaborate with on a project-by-project or hourly basis.

No full-time

We work with independent experts who love challenging AI, blockchain, and security projects — not full-time hires. You keep your flexibility; we bring the interesting work.
