Senior Talent Acquisition Recruiter

Location: US based candidates are the preference / Would consider Europe if they have some overlap with EST

Compensation: $150K - $200K

We help enterprises transform fragmented data into governed, high-confidence intelligence without sacrificing control. By bringing compute to the data through a private data lakehouse and a secure contextual AI framework, we enable organizations to audit, verify, and monetize their most valuable assets.

As a Senior Technical Recruiter, you aren’t just "filling roles"—you are the architect of our human capital. We are building at the complex intersection of AI, blockchain, and enterprise infrastructure.
