Preferred Qualifications:

• Experience working on a two-sided marketplace or platform serving both consumer and enterprise customers.

• Impact: Work directly on building the future of hiring, contributing to an autonomous AI recruiter that has already conducted thousands of interviews across multiple industries.
• Compensation: Competitive salary ($150,000 - $250,000) and meaningful equity participation (0.01% - 0.25%).
