Job description

About the Company:

Our partner, an innovative early-stage start-up, is building the essential commercial layer between information owners and AI agents. They are dedicated to enabling content creators to effectively price, license, and securely deliver their valuable data to the burgeoning AI ecosystem. Their platform offers sophisticated features such as usage-based dynamic pricing, granular access rights per agent, and comprehensive usage visibility, ensuring fair compensation and controlled distribution. With a six-figure paid pilot already underway with a major content owner and a second enterprise customer secured, they are poised for rapid growth with a seed round planned. They are now seeking a visionary Founding Engineer to join their team in either San Francisco or New York.

• Strong expertise in designing and implementing data pipelines.
• Excellent technical fundamentals, backed by a rigorous degree in Computer Science, Engineering, Mathematics, or Physics.
• Demonstrable full-stack development capabilities and a hands-on approach.
• Comfortable navigating ambiguity and making critical decisions in a fast-paced environment.

Compensation and benefits:

• Highly competitive base salary of USD 250,000.
• Significant equity ownership ranging from 0.5% to 1%.
• Opportunity to be the first in-house engineer, shaping the technical direction.
• Direct impact on product and business strategy from day one.
• Exposure to cutting-edge AI commercialisation and marketplace dynamics.
